How Manufacturers Can Fix Joystick Drift - Permanently!

[@silverywingsagain]

Just stopping by to remind everyone that Hall effect sensors are not new technology. They were used for the analog sticks for the SEGA Saturn in 1996 and the Dreamcast in 1999. Manufacturers don't use them today because they would rather your controller wear out so you have to buy a new one.

As an FPV hobbyist, THANK YOU for making a video (albeit a short one) about hall gimbals. There is literally no downside in using these over potentiometers besides the slight increase in complexity and tiny increase in price. It's so worth the added consistency and longevity and it baffles me that potentiometers are still the norm in expensive video game controllers.

[@placebomessiah]

one downside is that someone could wirelessly interfere with a hall effect transducer from a distance

this problem had already been solved in the 90s. the sega saturn analog pad, and the dreampad both used hall effect tracked joysticks, using 4 board mounted hall effect sensors, and a single magnet in the base of the joystick. the design was pretty ingenious, because the centering mechanism was practically impervious to mechanical wear too. even after thousands of hours of use, those sticks did not develop "center wiggle".

I wish they would release a replacement sticks for regular controllers just like they have done for steam deck. It will be a pain to replace them in newer harder to disassemble controller designs, but i think it would be worth it.

[@MentalEdge]

I think the reason they were able to do it for the Deck, is in it the sticks are fully modular, including the PCB they attach to. Meaning they could include the hall effect sensor on the small PCB that you replace alongside the stick. But in most controllers, replacing the thumbsticks means de-soldering the little stick module, but that doesn't include the hall effect sensor, which is on the PCB. Hence, hall effect replacement sticks for say the DS5, would mean replacing the PCB which the sticks are attached to, but in the DS5 that'd mean all the other guts of the controller, too.

It's just surprising that it's taking big companies this long to switch over to them. They are superior to potentiometers in every single way. And no, they're really not that much more expensive so cost of manufacturing is not an issue.

PS2 also has a giant deadzone in software, which hides the electromechanical issues somewhat, and much larger stickboxes than those used today, so they do fundamentally have more endurance.

[@lucianocarcagno9771]

Excellent video! The fact is that potentiometers are ultra cheap to manufacture and little is needed to make them work well enough. You could even add an offset value in the controller itself (added via software and editable) to correct drift but manufacturers won't let you change it. That could extend the life of your controller at the cost of accuracy. Eventually the compound used for the trace inside the potentiometer will wear out and no software fix will be able to solve drift. This is not the only (or better) solution though. Rotary encoders (optical ones for example) have been around for decades and those are almost wear free. No, those don't have an "infinite" amount of "steps" (not analog) but can have a really really good resolution. Along with some clever math and software you could make them work just as fine. Ahhh but the cost .... (sarcasm). Keep doing videos like this one!

[@pratikpramanik7782]

This. Also hall effect sensors CAN wear out as the magnets can demagnetize over time in extreme hot and cold situations. Also if using rare earth magnets, there are already shortages of the material required for making them. Opto/rotary encoders don’t have this issue if well sealed. Smoke alarms that use optoencoders all have useful life spans of over 10 years.

I've been going on about this issue with the antilog modules. I used to solder brand new ones in often to deal with the issue. I really like the solution of using hall effect sensors but I still feel like the little 3D gimball mechanisms need improving too. The are far too delicate and I found the mechanisms actually caused stick drift themselves as over time they don't center themselves very well and can cause that drift regardless of the condition of the alps resistor sensors. I really think other manufactures should go above and beyond and create something that is robust and maybe even ballraced or some type of mechanism with the hall sensors.

[@CBEnoddyy]

100% agree, Hall effect sensors do not remove the possibility of stick drift. The stick not returning too centre is the problem. I suspect the hall effect sensor has a lower resolution than a potentiometer and that's why it helps with drift, Which is something you don't want.

I've seen more than a few myself but usually in the opposite state where the computer thinks the lid is constantly open. This is an interesting concept for both applications!

​@@victortitov1740 Use sealed enclosure to mitigate the problem of foreign objects . Also hall effect sensors can easily get affected from the altering strong magnetic fields from the nearby devices such as built-in speakers in the controllers due to space constraint .This is the reason why phones and tablets do not use hall sensors to detect phone cover as they contain strong neodynium magnets but rather rely on the proximity sensor .It is easier to shield a device from light than than from magnetic fields . Capacitive is difficult to implement because you cannot induce charge from outside or conduct charge as you normally do with your fingers as the analog sticks are normally rubber coated and creating a capacitive array with high resolution in a small 3d space would not be economically feasible .Till now optics is the best practical approach

[@victortitov1740]

@@maxinventer static magnetic fields from nearby magnets can be canceled in firmware. Dynamic magnetic fields can be shielded by a steel enclosure. And i highly doubt these fields are strong enough to even matter - phones have magnetometers (compass) in them and detect the magnetic field of the earth without much trouble, which is way way wayy weaker than the field of a neo magnet in close proximity to a sensor. You don't need arrays of electrodes to make a capacitive sensor - just two pieces of metal will do, as long as they are close enough together that their mutual capacitance is vastly larger than that to surroundings. Then you just measure the capacitance in analog way. Pressure sensors commonly work in this manner.

[@maxinventer]

@@victortitov1740 Shielding will increase the size of the enclosure and dynamic magnetic field will always vary according to the audio signal and will require complex programming in firmware as even in 8 bit mode the ADC will have 256 steps . For capacitance based solution it will require a refresh circuit and since the minimum number of steps required is 256 in 8 bit mode it will require some serious shielding to prevent a drift in default capacitance values . I have made a dsp based on your approach in the past and the preset values tend to drift in real-time when used without shielding. Also the device will also need to pass emf and EMC test and will increase the pain of the designer . You are theoretically correct but the target of the design here is to accurately measure steps to avoid drifting and that can only be done by using higher bit resolution which will be very hard to maintain using varying charge capacitance . One typical example is when a laptop is run with an unclean power source the touchpad starts behaving erratically and goes out of calibration due to the use of a poorly shielded power supply.

[@janjohansson2567]

PS3 controllers used hall effect sensors as well according to Ben Heck. They also sometimes suffered from drift, but maybe to a much lesser degree than other consoles.

Doesn't matter how reliable the sensors are if the sticks themselves drift. The T-16000m especially already used Hall effect sensors and STILL experienced drift.

[@hashbrown777]

It's funny that the N64 had a clever LED-photosensor setup with no electrical contact points either. Their issue was that they buggered up the mechanical contact points though so the physical stick would wear down and not hold centre. Zero drift, but after a while it wouldn't pull itself to centre anymore, you had to hold the limp stick manually. If hall effects are expensive, I reckon repackaging the photoreceptor setup into this formfactor with the superior gimbal setup we have these days would be the best of both worlds and super cheap.

[@robinrai4973]

@@rafaelgsbr my potentiometers are busted after just 3 months of use on an xbox controller..

[@SianaGearz]

Indeed this also strikes me. The Dreamcast and flight sticks last forever because they ditch the XY splitter assembly and directly read the position of the magnet with 4 Hall sensors underneath, and do the axis transformation digitally. The lack of mechanical splitter allows them to put a large spring wrapping around the assembly which barely moves in use and thus doesn't degrade with time. Another problem in ALPS style sticks is wear in the joints of the XY splitter, again not a problem in prior existing Hall sticks. This assembly reintroduces problems of the ALPS style stick. Potentiometer lifetime is about as long as 3 mechanical assembly lifetimes on the Xbox360 pad, PS2 pad and several others. I only do old stuff but i know my way around it. I bet these guys invented a worse Hall stick in order to be able to patent it; the claimed usefulness would be drop-in compatibility (in a variant with trimmable opamps for example) against existing ALPS style sticks. Apropos interesting patents: Allegro has one which ditches the spring and uses a magnet instead, considering there is already a magnet dangling from the bottom of the stick. I'm looking at that and thinking: finally a patent that... while i dislike patents, this is specifically the kind of smart the patent system was invented for! Like you look at this and think wow, it's elegant and simple and nobody thought of this before?

[@freyalunar3633]

Although it may be because I'm a PC gamer first, I don't think I've ever had drift issues so much as the spring that centers the stick wearing down to the point that there's a large enough freely moveable space in the middle with no resistance. That is the only thing I've ever really had to adjust deadzones for for the most part.

[@batlin]

I appreciate how this good fellow pronounces his t's so clearly.

[@zensoredparagonbytes3985]

Sometimes you can mitigate a little bit of drift depending on which of the axis is affected, what action is required, and if the game or software supports it. 1. By adjusting the deadzones, or 2. for example when it affects running of the character, to map that action to another button if possible. I've had to do it in a few occasions. It's not a solution, just postponing the inevitable, but you can still keep using it until you can fix it properly.

[@rotor13]

Adjusting deadzones and re-mapping buttons delays or masks the problem. Hall-Effect or Optical sensors are better and longer lasting. The N64 controller uses an optical sensor and the thing that wears out is the analog stick itself grinding against itself, not the sensor. But because the stick and sensor are one unit, you just replace it. I had to replace it in my N64 very early on, just about 2 years after the n64 launched. Knowing what the actual failure is, using a little dab of lithium grease to prevent the plastic-on-plastic contact grinding itself into powder - that same controller still works to this day for my kids.

[@RealCelticGamer]

I'm looking forward to getting the Gulikit thumbsticks for my Steam Deck as they're using magnets too. Though even hall effect sensors drift eventually.

[@TheRealDJSigma]

A very similar thing happened in the DJ world. Originally, all DJ mixers used contact faders where a couple of brushes would move over two carbon tracks as the fader was moved. The carbon tracks could wear out, and dust/grime getting inside a fader could affect the contact between the brushes and tracks. That would lead to the sound bleeding or crackling - not good. Now many DJ mixers use non-contact faders that use optical or magnetic technology, eliminating the issues that contact faders had. I think whether companies use these new stick modules will come down to cost more than anything. I don't really buy into the "they want them to break so you have to buy new ones" argument, even though there is some merit to that, cos I think ultimately, they would prefer the consumer to have a better time with their products, have fewer customer service contacts regarding broken controllers, and create less waste. I would like them to use higher quality components all round tbh, cos I love the feel and features of MS's Elite controllers, for example, but I have had a bunch of technical issues with both the OG and Series 2 versions.

The worst thing is that Microsoft (and I guess Sony etc) uses Hall sensors in the Xbox One controllers, but only in the triggers. This is because the other benefit of Hall-effect sensors is that they have virtually no dead zones. They react immediately and predictably to inputs unlike traditional potentiometers, which makes them great for trigger actions like snappy shooting and progressive acceleration.

[@N_0_I_Z_E]

The Xbox controllers triggers use the same technology I would expect the next version of the elite controller to use these for the joysticks as well I'm tired of soldering on new potentiometers every 3 months for my controller

[@Klefth]

Hall effect sensors were in controllers ages ago. Sega used them on the Saturn and Dreamcast, and Sony actually used them in some early Sixaxis models, as in the very first PS3 controllers that had no rumble. I honestly think they simply didn't catch on because there is more money in selling controllers that will definitely break much easier, and the issue would've kept going mostly ignored if Nintendo hadn't pushed it as far as they did with the switch, making one of the most expensive 1st party controllers ever and also one of the most shoddily put together.

This is an interesting question and as others have guessed it may simply come down to cost but it's difficult to know without further investigation.

A simple solution without having to change hardware for the current existing hardware would be just to simply allow dead zone adjustments on every console on a per controller basis. Calibration for full motion and then a fully adjustable middle dead zone would help immensely. A large middle dead zone would eventually become a problem, but for minor to even somewhat drastic drift, it could cancel it out. It's amazing that dead zone settings aren't already a thing on all consoles by now.

The steam deck uses Hall effect sensor in the analog sticks. A way to make Hall effect analog stick cheap to manufacture is to take the design from the Sega dreamcast integrate the Hall effect ADC into the main I/O chip, integrate the top housing of the joysticks in to the top body of the controller, and use a smaller spring to further shave down costs.

[@amarokorama]

No, the Steam Deck does not use Hall effect analog sticks by default. But GuliKit, the manufacturer of the gamepad shown in this video, sells Hall effect analog sticks for the Steam Deck as replacements.

I'm not a gamer so hadn't come across this until someone brought a controller to a Repair Café I was fixing at with this issue - I gave it a clean but not sure if that helped or not in the end as he didn't have the console - this was a useful insight into the solution - kind of reminds me of why old fashioned 'ball' mice were replaced with optical mice over time!

[@placebomessiah]

I've always wondered why optical encoders haven't been adopted. So much professional music hardware is covered in optical knobs. Hell it's how pretty much every mouse works now, so it's not like we're lacking the tiny precision power efficient integration.

[@Aikano9]

They simply cost more.

[@SianaGearz]

Optical encoder happened, that's how the N64 stick worked! Honestly it's terrible, the splitter to translate the XY movement into separate X and Y wasn't well made due to unsuitable material choice (ABS - not enough abrasion resistance due to flake grafting), there was an attempt at gearing which wasn't that well conceived either, and there were only like a couple dozen steps of precision across the movement range, like maybe 64 tops. Which pro music hardware has optical knobs? I don't deal with stuff that costs above a grand, but i haven't seen anything, all purely electrical contact based so far, sealed oil type though, nice enough to last a lifetime. Except DJ controller platters, those are always optical.

[@placebomessiah]

@@SianaGearz literally hundreds of devices and it's not just limited to audio hardware. pretty much anything with a precision knob that spins forever. thanks to optical mouse technology, modern optical encoders have evolved to be incredibly accurate and cheap.

[@SianaGearz]

@@placebomessiah Not "literally anything", lots of indent-free contact rotary incremental encoders, they're the standard solution really. Feel and work fine, when well made, and even in middling music gear, they've got some quality behind them. Naturally not forever unlike optical. Optical devices have a flaw, they need to not accumulate dust, and at small sizes they need to be fully shielded, which is way more difficult than it seems; this isn't the case with mechanical ones, the oil pressure just doesn't let any dust come in so the seal can be fairly loose and they'll still run for a couple decades. Making a tight seal is a near impossibility since you want that shaft to rotate easily. Or like DJ turntables there there is often just the bare minimum of shielding but the optical gaps for rim sensing are so generous that they just won't get clogged up in a reasonable time. I mean obviously people still manage to clog them up sometimes. Another interesting issue is in the optical absolute encoder crossfader Behringer made for some of their higher end DJ mixers, which is nice enough, should last an eternity... unless it happens to be used near a fog machine, where it will temporarily glitch out. Not great for the intended usecase. Also nothing to do with optical mice necessarily. You remember ball mice? They split the ball motion onto two shafts which were read by optical incremental encoders. That's still how incremental optical encoders work, not with array imagers and DSPs that optical mice use. They didn't reach very high step counts, unlike possible with sealed optical encoders, though those have a considerable cost to them.

[@TechGamesAU]

It’s not just up to manufacturers to adopt this, it’s up to us as consumers.

[@DragRedSim]

I can think of a few reasons why the analog potentiometer is still the standard in gaming. Apart from the cost and availability of components, one thing that springs to mind as an issue is the effect of rumble motors. These operate by generating a magnetic field, and the controller would need to be designed from the ground up such that the effects of having the rumble motor running would not be detrimental to the accuracy of the stick. Whether that’s through greater physical distance between the sensor and the motor, such that it’s not affected, or by compensating in software, it’s an extra design consideration that the analog devices just don’t have. Another issue, specific to the Joy-Con at this point, is the physical throw distance. Joy-Cons use very low sticks, by which I mean the point on which they pivot in both the X and Y directions is a lot closer to the thumb than it is on other joystick designs. This means it’s harder to package the sensor in the joystick unit, and to have enough physical movement of the magnet mounted to the joystick to be able to affect the Hall sensor enough to get the accuracy wanted in the output voltage. Even with all these things taken into account, the centering effect of the stick is only as good as the physical mechanism on which it relies. If the spring on which the joystick rides fails, it’s the same problem whether your stick is using magnets or resistors to read its value. This is also another argument towards the potentiometer-based device; it’s available as a single unit which incorporates a standardised upright. A Hall-based solution requires engineering the physical action of the stick separately from the sensor mechanism, raising the design complexity. I do find it worth noting that certain current-gen controllers do use Hall effect as a matter of course, specifically in the analog triggers on the Xbox controller; and these have their own vibration motors in close proximity. I suspect they are using software compensation.

[@iFixitYourself]

This is interesting! I'll certainly read up on this and see how Gulikit approached the problem. Do you have any references for this information?

[@DragRedSim]

@@iFixitYourself In terms of references, I don’t have any documents; this is speculation on my part regarding reasons why Hall effect isn’t the standard. Most of this actually comes from my experience in sim-racing hardware. I have a Thrustmaster T-LCM set of pedals, which use a load cell to detect braking force, and Hall effect sensors to monitor the acceleration and clutch pedals; the arms of the pedals are made of ferrous metal. However, when I tried to mount vibration motors (the same type as used in 360 controllers) which were connected to a separate device for control, I found that the interference from the motors being activated would cause the accelerator pedal to stop responding. Since they’re separate devices, and the pedals are effectively a “black box” in that I can’t alter the firmware of them, it’s not possible to apply the software compensation I mentioned. However, I believe that other pedal sets which do have motors integrated as an option are not affected in the same way; whether that is through software (ignoring readings when the motor is known to be active, for example; if the motor is being driven by PWM, it may also be possible to take readings when the motor is off) or physical separation; I haven’t used these, so I can’t tell either way. It may be worth repeating the experiment shown on the Gulikit controller while holding a small motor (driven from another device, such as an Arduino) nearby, and see how it reacts when the motor is both on and off. The rest of the effects I mentioned are speculation on my part; the physical design of the joysticks on the Joy-Cons are known to be small packages, as can be seen from replacement parts, while the spring argument is basically saying that it’s easier to design the whole controller if the functionality of center return is already provided by the joystick module, rather than adding it in separately. I have no experience in industrial electronic design, these are all speculation on my part as to reasons why, partially based on my own experience. I also want to note that the PS5 adapter triggers still use potentiometers to determine their position; since they have motors in very close proximity, it may not be possible for them to be substituted with Hall sensors in the manner that the Xbox triggers use.

[@SianaGearz]

Dreamcast had an interesting quirk that a number of screws in the controller anywhere around the Hall stick had to be out of NF metal, something bronze like. I think they puzzled around with screw placement and overall construction a little to make it work, it sure makes that impression. Indeed the rumble motor was VERY far from any Hall hardware but i don't know whether that has anything to do with that or whether it just worked out like that. I could certainly create some interference nearby and check next time i break out the Dreamcast. Besides Hall stick the triggers are also Hall.

[@luigimaster111]

So, the issue outlined here can also be caused in part by the by the joystick's centering mechanism wearing down, there is a lot of plastic on plastic contact in there, and over time that will cause the stick to not center and feeling rather loose. You can currently buy joystick components that function and fit the same as the plastic ones, but they are all metal, which lasts a lot longer and feels a tad snappier. I've refurbished a lot of xbox 360 wireless controllers with these parts. I started doing this when I noticedy twenty year old well loved Saitek controller had almost no joystick wear, while my significantly newer 360 controllers had so much wear it was unusable, then I popped them open and noticed the difference.

[@hellandbackhoe]

If you remove the circuit board that contains the hall effects sensors and then demagnetize it. It will fix the problem of the sensors becoming magnetized over time due to their proximity to the magnets.

So far I’ve not had a single controller having drift. However, one thing I never do is never add pressure to the stick while turning. And I have my thumb on the outer edges, not laying flat in the middle Center of the stick like many people do.

After watching the video, I have two questions. 1. This problem hasn't arisen until recently; how did past controllers have far better potentiometer quality when compared to today's controllers? 2. Wouldn't Hall Effect Sensors add latency as they output an analog signal that needs conversion to a digital signal?

[@Berengal]

1. They didn't. Potentiometer based sensors have always had the same drift issues, for example as someone who only played Playstation at friends' house I don't think I've ever used a PS1 or PS2 dualshock controller that didn't have really bad drift. There are multiple reasons why it's perceived to be more of a problem now than before: You might not have run into the problem yourself on older controllers; that's just random chance. The volume of failure has gone up because there are way controllers out there being used, the failures show up sooner because spend more time gaming and modern games rely more on thumbstick controls than old games; it doesn't mean the quality of the sensors have gotten worse. It's much easier to come across stories of failed sticks now than before because of modern social media. Older games often had low precision input (e.g. only two fixed walking and running speeds) and large deadzones which hid the drift. Finally, joysticks other than thumbsticks, with other types of sensors, were more popular, so drift wasn't something people were that aware of as a problem. 2. Pots also output an analog signal. There's no difference.

[@TheRacingDevon]

@@Berengal Thanks! Your points gave me a new perspective and helped me learn a few things today. However, I still can't help but wonder if the quality of potentiometers in controllers truly hasn't changed for the worse, especially when compared to the Nintendo Switch Joy-Cons. Otherwise, when I think about it, yeah, I didn't have as much time to play video games in the past compared to now (let alone even afford it), so maybe you're right. I quickly read that there were analog and digital potentiometers without actually understanding what they were; it makes sense now.

Inconsistent field strength of production magnets that might necessitate more calibration which is highly labour intensive.

[@nerdstrangler4804]

Definitely not cost. Hall sensors are not expensive. Microsoft switched the triggers from potentiometers to hall sensors when going from 360 => xbox one. I suspect the reason is probably tied to why all the manufacturers making "crappy" thumbsticks have no problem giving you durability testing results, while the guys making the ones that supposedly never go bad won't. There is probably some engineering reason why potentiometers are favored over hall sensors in thumbstick applications. I suspect once these have been out in the wild and start accumulating some wear and tear we will get a better sense of why that is.

[@SianaGearz]

@@nerdstrangler4804 I can see two issues in this Hall design. That it retains the deformation prone tiny return spring and the wear-prone splitter assembly, both of which are not a problem in other Hall sticks but are problems in potentiometer based sticks. I don't think it will last. Dreamcast used Hall but it looks like they puzzled around a bit with suppressing interference, such as with screw placement and choice, and relative placement of different Hall controls such that they don't interfere with each other. It might be one of several reasons why it's kind of an oddball controller by look and feel. On the flip side that Hall hardware in that one actually lasts forever; great application of force management, minimal spring deformation, correct lubrication, no abrasion whatsoever. The lubricant will decay but you just replace it and you're good again for the next 10+ years.

[@madmax2069]

Hall effect won't really eliminate stick drift, because a lot of the times stick drift is due to the centering mechanism getting sloppy/worn out over time (too much plastic in the mechanism, and quite often the spring used to create tension to return the thumbstick to center loses it's strength to be able to return the thumbstick back to center). Hall effect will eliminate dirty potentiometer issues like erratic movement in game during when you're moving the thumbstick (see Atari 2600 paddle controller dirty potentiometer issue), but HE won't really cure stick drift as the thumbstick usually still has a tight connection to the potentiometer. The plastics used in the centering mechanism will get worn down, and when wearing down it'll also produce a fine plastic powder that coats everything inside the centering mechanism, not only will it cause the drift issue as well it can also make the thumbstick is harder to move smoothly.

[@wedgie502]

As a radio control enthusiast and flight sim pilot, I can say that you are wrong. the plastics used in most game controllers as well as R/C and flight sticks are very durable and springs can typically be replaced, so long as the items are well cared for and not dropped a lot. For my R/C helicopters, I used the same radio for ten years (Spektrum DX7) and didn't bother with an upgrade (Spektrum DX8e) until I got my first drone and found out that my software wouldn't work with it. My sim controllers had other components fail (external wiring) LONG before the axis sensors did (Logitech X56). As of this comment, I currently have over 2200 hours on MSFS 2020 and DCS with my Thrustmaster T16000 flight controls. I will say that I need to get some powdered graphite to lube the throttle and rudder pedals as they suffer from way too much friction. In the game controller (D-pad type) arena, when the pots start to wear down, the signal gets erratic and true center can be harder to define without adjusting deadzones. Yes, the axis still has a tight connection to the pot but the pot is too worn to be accurate. This is where Hall effect is superior. Hall effect does not need deadzones as it doesn't wear out like pots. you instead adjust the sensitivity with expo curves and you get 100% control for a VERY long time. In closing, don't sell hall effect short, you'd be surprised at the performance gains that you can achieve with it.
