Spencer Notes

From Spencer Featherstone.

Notes from Assistive Devices

Editor's note: It looked sort of messy. Couldn't make sense of it.

Cheap to do

Thinking about adding a summary something like:

• sensor & {motion data outputs / desired motions}
• gyro (accel??) rotational (ie an angle, or angle change/time) <<<<<< can hand or finger be used .... and map angle/change to onscreen movement???
• accel - g's in relative or absolute directions
• accel - tilt/orientation (v limited angles??)
• combinations of above???? - eg via kalman
• motion detect, tap, shake, gestures, more????
• everything in relative/absolute direction/strength
• ... plus min/max thresholds, scaling, ......
• " air‐mouse" - ie mimic standard x-y mouse movement, but "in the air"

User actions ...

• to control mouse (so just looking at x/y equiv inputs ... keys/switches discussed separately)
• entire finger hand shape/position/movement - eg leap motion system
• move this way
• eg move or wave finger/hand/....
• tilt hand(rotate wrist)/arm
• point at position
  • finger/hand
  • eyes (camera eye track, muscles signal, ...?)
  • head
• mouth - open/close, sip/puff
  • muscle action (eg via electrical impulse)
  • EEG brain control
  • gestures = each dif input method can have a host of gestures - shake, tap, swipe, flick

Intuitive ..

so movement in direction of desired mouse movement and amount of movement relative to size/speed/acceleration of movement
