Hi,

I am trying to extract X Y drawing coordinates from a tablet (sort of touchscreen) that is connected to my computer using a USB connection. It is not a wacom tablet (so I can't use the great wintabmex functions). Does anyone have an idea on how to extract this data to matlab?

Thanks! Naama

What kind of tablet is it then?

I would hazard a guess that it creates a virtual serial port and communicates via serial -- that was a common design for non-USB tablets.

Hi Naama,

Try using Psychtoolbox PsychHID functions because it will help you read the raw data from the tablet, including the X Y coordinates of the drawing. For more information PsychHID function, please refer to
