moment it is just a specific accessibility tool.
I think that this raises an important point about inclusion of accessibility features: they are often very innovative, and they enhance the experiences of average users. For example, the on-screen keyboard can be adapted for use on touch-screen devices (at least this is my understanding from discussions I had with Nohemi Fernandez while we were in Montreal) - as long as someone extends the code :)
Since the trends right now are moving away from mouse use, it might be helpful/interesting to ask ourselves whether or how cameras can be used to replace them. Are there situations in which a camera would be more useful than a touch screen or track pad? Certainly it can be for certain users with disabilities, but we might want to explore other use cases, as well.

please, read again the feature proposal name "Alternative input based

About performance, it is something that was always one of the priorities
for eViacam developers, and the reason that the configuration wizard
allows you to tweak so many parameters.
See my previous comment about performance.

I also think that performance and facial gesture support will most likely improve faster if this is included and available to more users and developers.
