The user can activate the system with a gesture and then choose a command from a menu with another one; repeating the activation gesture carries out the command.
They can activate that gesture by attempting to do it, and the latent muscle signals created as their limb attempts to do so are detected and passed on to the prosthetic, which will itself recreate that motion.
It also required something of a lighter touch than I'm used to; I tend to rest most of the weight of my hand on my mouse, apparently favoring the left side, since the Lexip tended to activate the "left" gesture now and then (certainly my fault and not a bug, just saying).
The application describes how the Siri app could reside in the dock or in the background, and be activated either by gesture or by voice activation – a good candidate would be the "Hey, Siri" voice prompt that Apple introduced with iOS 8, which will allow phones running that OS to respond to the command when connected to power.
The gestures can also activate an activity menu to jump to particular places within an app.
Our results suggest that for normally functioning adults, imitating a gesture activates neural processing of the intention (or goal) underlying the observed action.
Similarly, observation of meaningless manual gesture activates posterior superior temporal regions in observers who do not sign (Hermsdorfer et al., 2001; MacSweeney et al., 2004; Thompson et al., 2007).
Presumably overactive gesture activations could also feed forward to activate other aspects of the person identification/representation system.
It would need some kind of UI cue to let people know it was there, a gesture to activate it and deactivate it, and some basic parameters to make it play well with other elements.
This automatic processing might explain activity in the FFA bilaterally and in the right LFA normally activated by human gestures in response to robot stimuli.
