A limb action detector enabling people with multiple disabilities to control environmental stimulation through limb action with a Nintendo Wii Remote Controller.
A $20 Wii Remote plus free software turns the smallest limb twitch into a reliable switch for toys, music, or lights.
01Research in Context
What this study did
Two adults with severe motor limits tried a $20 Wii Remote as a limb switch.
The Limb Action Detection Program read tiny arm or leg movements.
Each wiggle turned on music, lights, or a fan for a few seconds.
An ABAB design showed the tech worked when it was on and stopped when it was off.
What they found
Both people quickly learned to wave the limb that held the remote.
Their limb actions jumped only during intervention phases.
The Wii setup gave reliable on-off control of fun stimuli.
How this fits with other research
Shih et al. (2012) kept the Wii Remote but tied the same movement to work tasks, not free play.
Lancioni et al. (2011) swapped the Wii for a microswitch yet got the same lift in independent control.
Carr et al. (2002) ran an earlier microswitch study and saw equal happiness gains, proving the good feeling is not about the brand of switch.
Together the four papers show any cheap switch can turn tiny motion into big environmental power.
Why it matters
If a client can twitch a finger or lift an arm, you can strap on a Wii Remote and give instant reinforcement.
No soldering, no grant, no wait for DME approval.
Try it next session: pick a favorite song, set the LADP to play it for three seconds, and watch the limb move rise.

03Original abstract
This study assessed whether two persons with multiple disabilities would be able to control environmental stimulation using limb action with a Nintendo Wii Remote Controller and a newly developed limb action detection program (LADP, i.e., a new software program that turns a Wii Remote Controller into a precise limb action detector). This study was carried out according to an ABAB sequence in which A represented baseline and B represented intervention phases. Data showed that both participants significantly increased their target response, thus increasing the level of environmental stimulation by activating the control system through limb action, during the intervention phases. Practical and developmental implications of the findings are discussed.
