Perhaps a row of iPads (thinking of the way Cerebral Mechanics made a virtual optokinetic grating cylinder from a box of 4 monitors (OptoMotry).

Thanks, Yury.

Most of our tests are at arm's length, so an iPad is too small to allow the
necessary eccentricity range, unfortunately.

Best, Gislin

Apple has nice touch screens. Did you try iPad? I use them for eye-hand
coordination test.

Dear colleagues,

For some of the eye-hand coordination tests and phosphene mapping tests
in my lab we have been using touchscreens for a number of years, but we've
not always been happy with their reliability.

With some, it appears that proximity of the finger is enough to register a
response, whereas with others a finger press goes unnoticed if the area
touched is too wide or the pressure too low.

Has anyone found a type/brand/model that they worked reliably for many
subjects?

If you have given upon touchscreens, what alternative (e.g., a 3-D tracker)
have you used instead?

Please feel free to respond in private or to the list.  I'll compile the responses
I get by this weekend.

Best regards,

Gislin Dagnelie
