13:03:35 <Zakim> agendum 1. "Accessibility of Virtual Reality - research synopsis" taken up [from jasonjgw]
13:03:40 <janina> scribe: janina
13:04:09 <scott_h> present+
13:04:48 <janina> jgw: Added a para re physical movement as per our call last week
13:05:44 <janina> jgw: i.e. some users may be unable to make certain movements
13:06:14 <janina> sh: Looks great!
13:07:09 <janina> sh: Found some lit re movement in gaming, but not vr specifically
13:07:28 <janina> sh: Can followup by next call
13:08:18 <janina> jgw: Seems we're generally OK with this draft, so can move forward
13:08:40 <janina> jgw: We need to think how our findings can inform authoring as that's the Workshop focus
13:09:18 <janina> jgw: We believe tooling may be unavailable for a11y support, so too much coding required
13:09:47 <janina> jgw: Asking how we should address authoring?
13:10:15 <janina> sh: Perhaps first get Shadi's feedback?
13:10:38 <janina> jb: He'll be in Cambridge next week, so I can prepare him
13:11:52 <janina> jgw: tooling -- libraries, etc
13:13:51 <jasonjgw> Janina queries whether it's generally true that VR needs specialist tooling than other applications do for development. If this is the case, there are probably efforts in this direction and we need to inject accessibility support into those discussions.
13:14:47 <janina> jgw: Recalls APA meeting wanted to focus on supporting hw
13:16:28 <jasonjgw> Janina: there's less customization and greater out of the box support for accessibility if it's introduced into the tooling/infrastructure. Some author knowledge is still required, but it's reduced.
13:17:28 <jasonjgw> Janina: if the focus of the workshop is on authoring, waht appraoches and cobminations thereof will be the focus?
13:18:33 <janina> jb: Still trying to reconnect the person met at a conference who's already focussed on a11y in vr
13:18:52 <janina> jb: Seemed his company may have their own
13:19:07 <janina> jb: Believe Dom most interested in meeting with developers
13:20:06 <janina> jb: Seems it's platform by platform
13:20:13 <janina> jgw: Which would make it more difficult
13:20:43 <janina> sh: Any work on how a screen reader would work in a vr environment
13:22:47 <janina> sh: Wondering about any work for consistent AT implementation in VR
13:24:29 <jasonjgw> Janina notes systems whereby metadata are preserved about the location of a sound (e.g., for up to 128 objects). With sufficiently many speakers, objects can be moved around the listener in 3D space.
13:27:55 <Judy> Judy has joined #rqtf
13:28:30 <jasonjgw> Janina notes a VR status report in the current issue of Sound and Vision Magazine, which is also addressing the 3D audio technologies.
13:30:08 <jasonjgw> Judy is generally satisfied with the VR research synopsis, noting formatting issues in the References section.
13:32:22 <jasonjgw> Janina: implementations of 3D audio are now widely available, greatly increasing the number of speakers used in the hardware configuration.
13:34:00 <jasonjgw> Janina: the Sound and Vision review identifies issues with lag in VR systems and recent improvements in this regard.
13:35:55 <janina> jgw: Recalls reach constraint discussion from APA VR call
13:37:51 <janina> sh: Notes great work on the VR writeup

13:38:34 <Zakim> agendum 2. "Task Force updates - TPAC meetings, Web authentication specification, etc." taken up [from jasonjgw]
13:39:08 <janina> jgw: Reviewed authentication spec
13:39:32 <janina> jgw: provides an api supporting creation of new identities
13:40:11 <janina> jgw: So web app need not concern about authentication, it's all client side using pub key crypto
13:41:21 <janina> jgw: Notes it's a complex api with considerable change since earlier review
13:42:28 <janina> jgw: Requires unique identifier for authentication module/device, server can identify device type, hw, etc
13:43:16 <janina> jgw: May be specific scenarios requiring certain kinds of devices that could impede a11y
13:45:41 <janina> jgw: Might this require a W3C note? WCAG coverage?
13:46:41 <jasonjgw> Janina: the outcome of APA discussions last year suggested that the accessibility issues are most pertinent at the next layer - where devices and their characteristics are discussed.
13:51:22 <janina> sh: Offering to look for lit
13:52:24 <janina> sh: re WoT ...
13:53:09 <janina> sh: Progress--MAY, emphasis, MAY have late week
13:53:42 <janina> sh: Possibly could do update for the group soon
13:54:26 <janina> jgw: If you ping, I can add to agenda
13:56:52 <jasonjgw> zakim, bye
