Dáskalos - an interactive science teacher for augmented reality

Dáskalos is an application for Augmented Reality, especially the Epson Moverio BT-200 smart glasses. The app will be available on the Moverio App Store shortly.
Teaching nature sciences can be hard, especially for more abstract themes. Dáskalos makes learning fun and explorative again. Usable both for beginners and as an interactive reference book, it shows information about such diverse topics as platonic solids, optical lens systems, momentum conservation for pendulums, atom models with fusion, vector analysis and many more. The content is fully interactive and the interactions playful - and not boring and grey. The topics immediately become more tangible and easier to grasp, as they deal with spatial phenomenons that are hard to explain in books or static graphics. Knowledge can be transferred in a more direct way and is embedded in beautiful interactive models and systems which is one point badly missing from many AR applications today.
This is a preview of Dáskalos Chemistry, which shows the chemistry part of Dáskalos in action. Atoms and molecules can be observed in augmented reality together with the accompanying print/screen learning materials.
Dáskalos works both with tracking markers and without. The markers are provided with Teaching Materials, a sample is available here: prefrontalcortex.de/labs/daska.... The Teaching Materials explain how the content can be used, what is shown, and provide additional textual information for the interactive models.
Hold the markers in front of the camera to interact with the atoms and molecules. If you remove a marker, the molecule will stay, allowing you to build your very own AR learning space in front of you. Also, you can drag the atoms around using the Moverio touchpad.

Amazing. Imagine teaching chemistry at this level of interactiveness

This is really Awesome !!

Cool

I need the documents that I print in a format. Thank you

[@toufiktb401]

Canal anyone help me to réalise that thnx

How did you make those glasses, what's their name?

[@prefrontalcortex1130]

Hi! The smart glasses you can see in the video are the Epson Moverio BT-200 www.epson.de/en/products/see-through-mobile-viewer/moverio-bt-200 - This was state of the art in 2015 and has since been discontinued. Today, you would certainly use a Microsoft Hololens or similar.

All models are wrong. Didn't anyone who actually knows chemistry point that out? These models are supposed to be showing in 3D the simplified version (compared to quantum mechanics) of the electronic configuration of 2 atoms and a molecule. Hydrogen atom. One electron should have been moving aroung a single proton on a spherical surface with a radius R1 instead of a circle on a single plain. So probably the animation should start as a whole and then show a cross-section. Oxygen atom. The same mistake is seen and also all electrons that are shown are shown as single electrons, while in reality there are some electrons that form lone pairs that each acts as a single entity. There should have been 2 spherical surfaces with different radii. The first one should have 2 single electrons, the second (outermost) should have 2 single electrons and 2 lone pairs of electrons. Water molecule. The circular paths of the electrons of the outer shell of O and H atoms intersect to form a bonding pair of electrons. This implies that the distance of the O and H nuclei is smaller than the sum of the radii of the atoms. This is wrong because when bonding occurs energy is at the minimum level and has a negative value and when the internuclei distance becomes smaller than the sum of the radii, energy sky-rockets and tends towards plus infinite. Thus the paths shouldn't be intersecting but just touching at a single point, where the bonding electron pair is formed. In the video, these pairs and the H nuclei remain still, while 4 single electrons (for the outmost shell) are moving around the oxygen nucleus, forming all types of angles with the O-H bonds. Again this is wrong. There should be 2 lone pairs and if the 2 bonding pairs remain still, so should the lone pairs, because the geometry of all electron pairs on the outer shell of the oxygen atom within the water molecule is fixed; it is an irregular tetrahedron (2 vertices/corners for the 2 lone pairs and 2 vertices for the 2 bonding pairs) with the value of the angles being: lone pair-lone pair>lone pair-bonding pair>bonding pair-bonding pair because that is the order corresponding to the strength of repulsion between different electron pairs. So either the entire tetrahedron remains still, or the entire tetrahedron (which will by necessity include the H atom nuclei) rotates as a single unit around the O atom nucleus.

Thanks for the detailed explanation! Please note that this video was done as a proof-of-concept in a couple days, it's not a finished application in the form shown in this video. Different atomic models are teached in different grades; all of them are simplifications on different levels. That being said - if you're interested in shaping the future of AR education, please drop us a mail! Well appreciated.

Hi, let me know if you are interested in collaborating on something like this. Thanks
