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

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

Dear colleagues,<br>
<br>
For some of the eye-hand coordination tests and phosphene mapping tests<br>
in my lab we have been using touchscreens for a number of years, but we've<br>
not always been happy with their reliability.<br>
<br>
With some, it appears that proximity of the finger is enough to register a<br>
response, whereas with others a finger press goes unnoticed if the area<br>
touched is too wide or the pressure too low.<br>
<br>
Has anyone found a type/brand/model that they worked reliably for many<br>
subjects?<br>
<br>
If you have given upon touchscreens, what alternative (e.g., a 3-D tracker)<br>
have you used instead?<br>
<br>
Please feel free to respond in private or to the list. I'll compile the responses<br>
I get by this weekend.<br>
<br>
Best regards,<br>
<br>
Gislin Dagnelie<br>
