Tablet question

christinahaywood — Wed, 17 Feb 2016 13:09:36 GMT

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

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.

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?

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>
