Thanks alot Catherine and Arend, I am using MovAlyzeR now, Which is the best solution for one how have no time for programming.
Hi, I'm not sure how you present your stimuli at present so can't be more specific, but the WACOM input tablets essentially act the same way as a mouse when you have the drivers installed. So you should be able to treat it as mouse input (with disabled mouse pointer), same as a touchscreen really.
Yes, we use the WACOM tablet with Matlab and the Psychophysics Toolbox. The input commands of the mouse work fine.
I developped my own scripts with Matlab and Psychtoolbox3. The tablets Intuos3 and 4 works at a stable sampling rate of 200 hz and recordings are fine to study writing and drawing. I don't know any commercial software, sorry.
We have been using MovAlyzer software to record kinematic data (e.g., duration, normalized jerk, velocity, etc.) on a WACOM tablet. The technical/sales/service support is pretty good too.
Peter de Jong can write bespoke software for the WACOM using OASIS software (additional fees are attached even if you by the kit simultaneously). There is some help available online to generate your own scripts but it is quite difficult. An alternative method is to use a touch screen monitor and DMDX software to record reaction times. Mouse movement on the touch screen can be captured and this data can be differentiated to infer kinematics of the hand. The downside to this set up is that there is some variability is sampling time. That said, DMDX is free, relatively simple to use in less complex tasks.
PsychoPy should also be able to take inputs from a tablet - see this thread here:

We used WACOM tablets with Presentation (www.neurobs.com) which also worked fine.
Like the first post, the digitizer acts basically like a mouse. Therefore, there are several options, it really depends on what kind of experiment you want to do with the digitizer and how well you can program or if you have technical support. You have programs available, like MovAlyzeR, which I would recommend (I am using it in my Lab) if you want to setup experiments relatively fast and your stimuli are not too complicated, however, you can make the stimuli more complicated by using MatLab to make the stimuli and than add an app to MovAlyzeR. Another program I use in my lab is OASIS, this software is a little bit more complicated because you need to be able to program a little bit, but a lot of functions are geared towards the use of Wacom digitizers, however, the program is MS-DOS based and works only on machines which run Windows 98 or lower (or you need to buy a box from KIKO software, which essentially is a MS-DOS machine), while MovAlyzeR works with all Windows based platforms (I am using it on Windows XP machines). The last option is to program yourself or using some MatLab toolboxes, which often takes much longer to get an experiment running, however, you will know exactly what is happening when collecting, processing, and analyzing data. In summary, it all depends on your time line, your capabilities to program, and your budget. Hope this all answers some of your questions.
Hi, Catherine , I have the same problem ,I want to record information from tablet ,but MatLab give only x and y, no information about pressure or pen tilt , I hop you found a solution that can be helpful to me .
I think that Wacom graphic tablet is provided with the necessary software. anyway, you may find several usefull answers in the web
Sorry za ha but we only collected x and y as well as reaction times. I cannot help you with pressure or pen tilt and I do not even know if it is possible to gather such information.
Just a quick answer for Za Ha; MovAlyzeR and OASIS (see my post above Dec 5, 2012) both can give you tilt and pen pressure data (if the tablet does record them). Also in MatLab you should be able to access these data and thus be able to record them (again assuming that your digitizer does record them; just a warning, some tablets do not record pressure levels, some digitizers only record if the pen is on or of the digitizer, and many tablets do not record tilt). Furthermore, if you use pen pressure data, be sure to calibrate and to look at the driver properties; The default relationship between pen pressure and level number is not always linear or even the same between digitizers. You can find this relationship in the driver properties and often you can change it (e.g., in all Wacom Intuos digitizer models). I hope this helps.
Thanks alot Catherine and Arend, I am using MovAlyzeR now, Which is the best solution for one how have no time for programming.
