I'd like to build a handheld pendant controller. I have some ideas about how it should work. One thing I want is an LCD screen. This could evolve into a "smart pendant" that can do things like move along an arc, rather than just one axis at a time.
I think the best physical interface from a handheld device to the computer is USB. Is there a way to get data from USB to HAL? I could use a USB virtual serial port but then the question is getting serial port data to HAL. Maybe the best interface is wireless, so how to get data from a UNIX socket to HAL? Note that we don't need "hard" real-time to the computer. Latency of a few tens of milliseconds is acceptable for a human interface so this could be done in userspace. If so, then maybe all I need is a way to get data from an arbitrary Linux application to HAL. It just occurred to me that this "arbitrary Linux application" could be the Apache webserver. Then you run a browser on the tablet.
