Gesture control & other tablet accessibility tweaks, media renderer
 

I've dug out an old cr@ppy x86 tablet (Dell Venue Pro 11) and loaded KDE neon to serve as a Jukebox/presenter on my porch when having friends over.

I was using a RasPi before, but this is marginally better.

I'm really not expecting much from this device, and it certainly delivers.

The integrated touch screen was probably the biggest reason, but other issues occurred to me that I've not found good/great solutions for.

I'd like to minimise the need to actually get up touch the device to interact, so these seem to be mostly Accessibility functions I would expect to be easily available to the disabled community - something I'm heading towards with age myself.

Questions such as:

• are there other means of input or interface-control?
  • i.e. can I use the webcam to read simple gestures, such as (MPRIS/DBUS) play/pause, stop, next, volume up/down, etc. define $arbitrary action
  • voice control?
• I've (kinda) managed to get it the act as a bluetooth speaker/a2dp-sink, but controlling playback does not work as well as expected
• Are there any other stable ways I can use it as other media renderers, so that guest on my guest wifi can simply send to it - I've not found any myself
  • chromecast
  • miracast
  • airplay
  • (DLNA is OK)

I recognise these seem like 2 different topics, but they're not as widely separated as one might think, as it speaks to a more intuitive, human-friendly ways of interacting with tech-ubiquity rather than needing deep expertise for simple tasks.

Interesting questions there.
What answers did you find? I expect putting something like "linux accessibility input or interface control" into a search engine should give some meaningful results?
Same for the other questions, e.g. "linux screencast" etc.
