I'm looking into what's required for Itinervate (as well as the head-worn input device and spacial audio idea I had) and this could be a project over 15x the workload that I could realistically manage. Here are some of the issues:

• There doesn't seem to be a convenient development board / sbc that is more powerful than a microcontroler but not as power intensive as a normal SBC like a Raspberry Pi Zero. I'm essentially looking for a low-end smartphone SBC most likely, but it seems most of them run chips intended for tv boxes.
• I'm still under the impression that visuals without a quick HCI has limited use. I've been mentally keeping a note of how many times my itinerary changes and let me just say "Wouw!" because anything I'd plan would be out of date within the hour.
  • I've recently found out that the Rayneo X2's only support 1-axis swipes and taps, unlike INMO Air2's 2-axis trackpads, and it already sounds quite limited. At least with things like trackpads or square optical sensors (as seen on UMPCs) would allow for great use of the 8vim layout with the added benefit that the user doesn't have to become Danny Phantom.
  • What I'm trying to say is that until otherwise mentioned, I'm merging the visuals with Tetrinsics and audio. I mean I'd have to have audio anyway, so that I can hear #Interval Provisional [gd0097] chimes.
