Hello,
I would like to perform a tapping manipulation in which the stimulus is presented on a computer screen (programmed using Inquisit) and the tapping response times are recorded using a tablet (Microsoft Surface 3). How might I go about doing this to ensure that Inquisit both presents the stimulus on a computer and receives response information from a tablet?
Thank you,
Christina

If I understood you correctly, you want a regular computer serve as the "display" and have a separate tablet (the Surface) serve as the "input device". Correct? If so, I'm afraid I don't see a way to do this.
Edit: I should add that -- if the tablet in question is a Surface Pro, i.e., if it has in Intel x86 processor and runs a full Windows version -- you should actually be able to install and run Inquisit 4 on the tablet. Stimuli would be displayed on the tablet's screen and input could be taken via the touchscreen by setting /inputdevice=touchscreen. Under Inquisit 4 (and below), touchscreen input essentially works the same as mouse input, i.e., you can define a tap on an on-screen object as response:
<trial mytrial>
/ stimulusframes = [1=a]
/ inputdevice = touchscreen
/ validresponse = (a)
</trial>
<shape a>
/ shape = rectangle
/ color = blue
/ size = (10%, 10%)
/ position = (50%, 75%)
</shape>

Thank you, Dave.
Just to be sure, there is no way that Inquisit running on a tablet can be synced with Inquisit running on a computer?

For syncing the two devices -- both executing Inquisit -- you would have to have them communicate them via their respective serial or parallel ports. To the best of my knowledge, getting a parallel port in a tablet should be difficult (if not impossible). What may be possible -- if the tablet has USB ports -- is to attach a USB-to-serial adapter to it and use that to send TTL signals from the tablet to the computer running Inquisit.
Hope this helps.
