[round table introduction]
harry: welcome to haptics for accessibility session
… emails available for further discussion
<xiaoqian> slides
harry: go through ToC
harry: introduction of Tencent Game team
harry: background of haptics
… Haptics amend human machine interaction
harry: Haptics Taxonomy
Harry: here are some reasons worth mentioning to improve usability and accessibility
[show how to start designing a Haptic Effect]
Selen: Versatility and flexibility are the core design concepts throughout the entire solution
Selen: show how to implement haptics with their SDK
Selen: MTGPA Haptics .HE Format shows in picture
… data format is also compiled with IEEE standard
Selen: Sync to Audio and Video Design
… designed 2 solutions
… Vibration playback mechanism and Vibration Synchronization Scheme
Selen: Haptics has implemented in Games
Selen: background of users, and haptics can help visually impaired users to gain more information and understanding.
Selen: use cases include: chat, news, videos etc.,
Selen: Haptics solution for input method
Solution for maps
Selen: Promote Haptics as a Common Human Language
… Integration with Web contents, support by Web platform, adoption in Accessibility guideline
… harry will introduction standardized about haptics
harry: the fragmentation will cause a compatibility issues, there are several advantages to standard haptics, since we improve the usability
harry: haptics stack show in slide
… some standardization work has start in different org
… including: ISO MPEG-I, IETF Haptics Media, IEEE P2861.3/Haptics Industry Forum etc
harry: Haptic Data Model in MPEG
… 3 types format
… depend on situation
harry: Haptic File Format
… 3 types format
harry: introduction of encode and decode
… 2 types of input and 3 types of output
Harry: IEEE P2861.3 Haptic Enhancement for Mobile Game, for mobile haptics platform: interface, data, evaluation
angel: suggest to jump into your proposal
Harry: sure
harry: Some Thoughts on W3C Vibration API
… doesn't support sophisticated haptic wave forms
… doesn't support precision haptics
harry: Some Thoughts on W3C Gamepad Extension API
… show possible amendment for W3C standard
harry: examples
harry: some takeaway
… raise some questions
mattreynolds: I edit that API, and implement into Chromium
… I can give you more context here
… basically decided that is going to be delegated to legacy device support
… planning on adding new effects to interface
… still a lot of work to do
harry: are you consider a new API for that?
mattreynolds: yes, MS is working on an update to explainer
… can't tell you exactly last I heard
<xfq> https://
mattreynolds: also we want this work for service too, and with more devices
… I don't think we are going to tie specific to USB
cabanier: good to see this going
… we have an applications to create waveforms
Harry: I assume also support openXR APIs?
cabanier: yes
harry: there are also some XR work in W3C, how you promote those in two groups
cabanier: @@
chunming: does haptics consider feedback from user?
harry: no guidelines to say that, we also confused.
… now way to determine
… if we define haptics as human language, I think we should work on guidelines and rules
Matio: maybe could be possible to make some simplified font of device, to create feedback
… not only to accept some but by some movements to create
PHANTOM
<xfq> Phantom from 3D Systems
mattreynolds: last slide open questions
… 1 is the easy one to implement, we can cross the system API
… 2 yes, to across the device
… I think we have decided that it would be good to have active waveforms associated with haptic effects so that we could do the down sampling to support on plus or take full devices as well as the more modern devices.
… 3 Probably didn't able to have things to extensive use case, especially for accessibility. I don't really have a good sense of that.
… I think the rest of the room should provide feedback on that. And should there be a guideline for I think a guideline would be good, but probably should not be part of the specification.
… @@1
cabanier: earlier question, controller can provide feedback
… like 3 or 4 pressure sensitive sensors on there
… use that develop can decide how to interactive
Harry: in conclusion what is proper way to move this forward
mattreynolds: little frustrating for us, by now we have a venue to discuss, we need to encourage MS to ring that proposal to a CG
… no CG yet
angel_: what about incubate in WICG?
mattreynolds: not sure, sounds like a path
