<div dir="ltr">LOW POWER OUTPUTS
<div>Instead of human-size robot arms to do remotely what humans want, many devices now have their own low-power self-contained motors right-sized for each job.</div>
<div>Imagining stapling 2 pages together at the office, done from home. </div>
<div>a) high power way: steer an industrial robot to hammer a mechanical stapler</div>
<div>b) low power way: emit a bluetooth command to an electric stapler, which has a tiny motor just powerful enough to drive a staple.</div>
<div>Similarly for many tasks with equipment - just emit bluetooth commands.</div>
<div>Perhaps where VR can come in handy: by providing a simpler intuitive interface to a plethora of self-powered wireless devices.</div>
<div>For example, in VR you would use a virtual pointer to point at the stapler, as if you were going to pound a mechanical stapler. That would be translated into bluetooth commands the electric stapler can understand to drive a staple.<br>
</div>
<div><br>
</div>
<div>Similarly for pushing wheelchairs in a hospital to substitute for infected personnel: </div>
<div>a) high power way: command a large walking humanoid robot to push the wheel chair</div>
<div>b) low power way - emit blutooth commands to an electric wheelchair which has tiny motors on each wheel.</div>
<div>And VR could simplify the interface, by clicking on the wheel chair, then a chain of points on the floor -a path- and the wheelchair would drive itself.</div>

<div>Q. what's missing from VR - what's holding it back from solving all the world's problems?</div>
<div>H: weak on outputs:</div>
<div>- great for input devices and building a virtual world and entering the virtual world and perhaps even solving problems in the virtual world. </div>
<div>x but weak on getting the virtual world results back out to do work in the real world</div>
<div>If so then perhaps this is the next things to work on.</div>
<div>And I can think of a few problems:</div>
<div>1) the real world has a way of updating itself, so keeping virtual world version synced is one challenge</div>
<div>2) output devices - robot arms tend to be expensive, and the more power they have, the more dangerous they are, so safety precautions </div>
<div>I can think of some nodes for #1, but not used to thinking about #2, I draw a blank</div>

- the soccer players are wearing HMDs. The HMDs show the soccer field from above - that's all they see. That's like a 3rd person shooter.<br>
As they look down on the field from 3rd person, they have to figure out how to move from first-person.<br>

To avoid that 3rd-person problem while decoupling the viewpiont from UserBody ray-casting and collision, UserBody can still be coupled to the avatar travel/pose -like your arms are attached to your body- so move with the avatar / relative to the avatar. That
might not be a requirement of any UserBody nodes, but might be how they are easiest to use.</p>

- Amela’s team is working on optimizing the 3D model with a goal of improving usability. There are many factors (adoption procedure and policy, etc.) involved before a mask/a design got approval<br>
- Feng expressed her interest in inviting her summer students to participate in the effort.
<br>
- Don reminded us to align the working group's long term goals with the current effort of the involvement of fighting COVID-19. To identify Web3D + UX research opportunities with the involvements.
<br>
- Feng is going to looking for COVID-19 research<br>
funding opportunities regarding Web3D and UX areas. <br>
<br>
2. Update the report from the last meeting. No progress on the following items so far<br>
- Due to COVID-19 impact. The following item still needs to be done. <br>
- Review Publications on Three types of interactions <br>
-- Create a folder in one drive – share with you all to collect Literature Review Publications on Three types of interactions – Feng (Done)<br>
-- Develop a spreadsheet to categorize the subjects with the papers we review - Amela.
<br>
-- List an “other” category for other UX related topics <br>
-- Collecting papers and put them into different categories – Amela and Feng<br>
-- Collect data/currents publications/papers and authors to invite to the group for later<br>
