Welcome & Announcement

Dom: TPAC registration has opened https://lists.w3.org/Archives/Public/public-device-apis/2016May/0027.html
... DAP will be meeting on Monday/Tuesday
... We have requested transition of Media Capture and Streams to CR; hopefully that will happen soon

Minutes approval

RESOLUTION: Minutes from 14 April 2016 are approved, https://lists.w3.org/Archives/Public/public-device-apis/2016Apr/att-0032/minutes-2016-04-14.html

Wake Lock API

Andrey: I still need to address the privacy/security aspects in the doc; not sure what next step should be

Dom: once we have the privacy stuff in, I suggest we start the wide review process
... this might give up more feedback, and if not, we shall move to CR

Andrey: sounds good

Sensors API

tobie: not much news since last time
... two specs: Generic Sensor and Ambient Light
... I'm waiting for feedback from the TAG on interactions between ambient light and sensor
... I should ping them
... I got very good feedback during the TAG meeting, with plenty good of comments (more examples, more upfront content on sensor polling)
... I'm planning to work these into the spec
... I've split up the generic sensor issue tracker into level 1 / level 2 / future work to give a better understanding on where we're going
... Intel is implementing it in Blink, which has generated feedback and spec issues that we're discussing
... mainly around timestamps (do we need them? are they costly? what do they really mean?)
... I'm waiting for some of the privacy & security issues in the paper that Lukasz shared
... I would like to get specific issues raised, both on generic sensor and ambient light
... I'm not too concerned on these issues at this moment; it's the usual trade-off between new features and privacy

dom: wide review schedule? device orientation?

tobie: wide review - we might as well start now; mostly minor editorial changes to the spec
... the implementation is pretty much working - not shipped yet, but no specific issues encountered
... I understand that both Mozilla and Microsoft are interested to follow through
... on my end, I think it's in good enough shape for wider review
... the TAG has mentioned specific things they'd like to see, e.g. exposing sensors in workers

dom: generic sensor & ambient light?

tobie: yes; ambient light is a really small spec
... there are some specifics (e.g. privacy concerns); but otherwise, its content is mostly based on generic sensor
... the main concern is how the two specs work together, and if this is the right split up
... people need to read both specs together

dom: earlier you had mentioned concerns about getting validation on the poll-type of sensors; where do we stand on this?

tobie: I feel confident enough on this now, thanks to some polyfilling work I did which highlighted a whole bunch of issues

dom: what about device orientation?

tobie: the Android and iOS implementations of the Device Orientation spec are built on gyroscope, magnometer, and accelerometer
... the way these are combined can vary a lot
... the device orientation only provides a high level view, while the underneath platforms have the lower level sensors
... so I want to work first on exposing the lower level sensors (magnometer, gyroscope, accelerometer)
... I don't really have a timeline on this
... will let the group know when I can move forward with this

<scribe> ACTION: Dom to start discussion on wide review of generic sensor & ambient lights [recorded in http://www.w3.org/2016/05/12-dap-minutes.html#action01]

<trackbot> Created ACTION-756 - Start discussion on wide review of generic sensor & ambient lights [on Dominique Hazaƫl-Massieux - due 2016-05-19].

Next meeting

Dom: on June 2nd; will try to get an ICS set up by then :)
