I've prepared draft for publication Tue 2 July dom: I can make the publication request fjh: thanks ... TPAC breakout sounds good, thanks ### Minutes approval fjh: Approve minutes from 11 June 2015 **RESOLUTION: Minutes from 11June 2015 are approved, [https://lists.w3.org/Archives/Public/public-device- apis/2015Jun/att-0104/minutes-2015-06-11.html][18]** ### Battery [https://lists.w3.org/Archives/Public/public-device- apis/2015Jun/0156.html][19] [https://lists.w3.org/Archives/Public/public-device- apis/2015Jun/0163.html][20] fjh: battery testing still in progress thanks to Intel, need work on Mozilla to progress anssik: person working on it in private branch ### HTML Media Capture [https://lists.w3.org/Archives/Public/public-device- apis/2015Jun/0157.html][21] fjh: do we know which browsers based on webkit are offering this HTML Media Capture and can provide test results anssik: code is in webkit, but work required for browser to use it ... we had blackberry browser, but that status of Blackberry OS is now unknown ... there are some forks fjh: so we have an issue related to two implementations anssik: is on chrome in android ... webkit places - apple, mozilla ok with accept attributes, similar but not exact, microsoft not clear ... maybe we should check with microsoft ... small amount of work with WebIDL to tie into platform dom: should we stop having only one implementation or try to get others; question of whether to continue with this ... is it useful anssik: can review use cases that are not addressed by accept attribute dom: if using instagram don't want to use photo gallery, part of rationale **ACTION:** anssik to contact Mozilla and Microsoft re interest in implementing HTML Media Capture vs shelving [recorded in [http://www.w3.org/2015/06/25-dap-minutes.html#action01][22]] Created ACTION-734 - Contact mozilla and microsoft re interest in implementing html media capture vs shelving [on Anssi Kostiainen - due 2015-07-02]. anssik: taking photo still hard on web platform if you need to use getUserMedia, so HTML Media Capture should be relevant [https://bugzilla.mozilla.org/show_bug.cgi?id=741393][23] fjh: if we do not have interest then I will send a CfC to shelve, resulting in it being published as a Note and work stopped ### Wake Lock API [https://lists.w3.org/Archives/Public/public-device- apis/2015Jun/0158.html][24] fjh: looks like this work is progress response, [https://lists.w3.org/Archives/Public/public-device- apis/2015Jun/att-0168/00-part][25] [https://lists.w3.org/Archives/Public/public-device- apis/2015Jun/0169.html][26] ### Way forward on Proximity Events and Ambient Light APIs [https://lists.w3.org/Archives/Public/public-device- apis/2015Jun/0159.html][27] fjh: we have choice, I think a lot depends on timing ... have not gotten much response to my question on the list anssik: we need better idea by having generic api better developed and then seeing fit dom: not sure if either in high demand, so can wait for a few months to decide ... most logical might be to build on generic sensor API ... I haven't heard concern about these two APIs being delayed or strong desire for them to move forward ... what is status of microsoft on these anssik: ambient light under development accroding to microsoft web page, shared this with Adrian and Travis ... they are aware that we are working on the generic sensor API fjh: summary - continue on generic sensor api path, with view toward moving Proximity and Ambient toward Generic Sensor API dom: know no strong interest in current APIs, concerns from Mozilla, possibility of confusion ... suggest we make clear that we don't expect to continue these in the current approach ... current consensus of group is toward generic sensor fjh: have only seen one response to my message, from Tobie proposed RESOLUTION: CfC to return Proximity and Ambient light to WD noting that approach will be generic sensor API based dom: suggest we publish with strong note that being based on Generic Sensor API ... not sure we should remove technical content anssik: add notes to editors draft, not sure we need to publish dom: it is important, some people are confused if TR does not match what is on our roadmap ... don't want announcement ... can publish using echidna (the new pub system) anssik: moved ambient light, will do for proximity **ACTION:** anssik to create editor drafts for Ambient LIght and Proximity indicating new approach toward generic sensor API, also drafts for publication to TR space [recorded in [http://www.w3.org/2015/06/25-dap- minutes.html#action02][28]] Created ACTION-735 - Create editor drafts for ambient light and proximity indicating new approach toward generic sensor api, also drafts for publication to tr space [on Anssi Kostiainen - due 2015-07-02]. **ACTION:** fjh to send CfC for WD publication for Ambient Light and Proximity once drafts available [recorded in [http://www.w3.org/2015/06/25 -dap-minutes.html#action03][29]] Created ACTION-736 - Send cfc for wd publication for ambient light and proximity once drafts available [on Frederick Hirsch - due 2015-07-02]. ### Device Orientation API (and Generic Sensor API) anssi: what is up with device orientation spec, no progress in 15 months dom: in May AC meeting disussed with Giri, unclear whether work will progress [http://w3c.github.io/deviceorientation/spec-source- orientation.html][30] dom: we need to decide whether to continue or not, Giri will bring back to group [https://github.com/w3c/deviceorientation][31] dom: also checking with staff contact for that group, have not heard DeviceOrientation Event Specification Editor's Draft 12 March 2014 dom: need to bring this up on geolocation mailing list anssik: concern over use of DOM Events ... do we need a task force for sensor related specifications dom: difference ambient light/proximity and device orientation is that device orientation is widely deployed and implemented ... should ask geolocation to finish standardization of current API ... then how and why to develop API on top of sensor API ... could do in DAP if agreed with geolocation wg +1 dom: reason is that not much interest in that group, and also developing generic sensor API, also rechartering **ACTION:** Dom to chat with Geo Chair and Staff contact on future of device orientaiton [recorded in [http://www.w3.org/2015/06/25-dap- minutes.html#action04][32]] Created ACTION-737 -
