Recordings will be made using:
o Wacom Intuos3 9"x12" digitizer USB
o Wacom digitizer driver 4.96-7 or later (DRIVER ATTACHED)
o Any PC running MS Windows XP
o MovAlyzeR 3.94 (or later).
To prevent trouble shooting the digitizer tablet settings and display mapping, use the following setup strategy:
1. Check Wacom driver version:
o Start >Control Panel >Wacom Tablet preoperties >About
o Verify you have 4.96-7 (27 June 06) (or later)
1a. If your Wacom driver is older, do a clean re-install
o Start >Control Panel >Add/Remove programs >Locate Tablet (click Support Information that it is Wacom's tablet dirver) >Remove
o Download driver from this posting or go to www.wacom.com >Support >Select your tablet and your system >Download and run install.
2. SETTINGS of Digitizer in MovAlyzeR
2a. Computer-wide settings
o Start MovAlyzeR
o Settings >Select input device >Select: Tablet
TROUBLE SHOOT: If Tablet is not an option you need to (re)install the driver.
o Click Acquire <==This wil update the sizes of the digitizer only.
o Measure and enter the sizes (in cm) of the visible display and enter the sizes
o Select Entire Desktop
WIDE SCREEN DISPLAYS. If your screen is a wide screen, map the (left) bottom part of the digitizer on the entire screen
o The Wacom Intuos3 12x9 digitizer's size is 30.48 cm x 22.86 cm (using 2.54 cm/inch. It is actually 0.0005 cm less). It has a normal aspect ratio of 4:3.
o Minnesota has a wide screen display of 30.5 cm x 18.3 cm (5:3 aspect ratio) ==> TWEAK the digitizer size to be 30.5 cm x 18.3 cm (thus the top 4.5 cm of the digitizer is not used). This makes the visual feedback REAL SIZE.
o Indianapolis: Dell Inspiron 1100 laptop display size has a normal (30.48 cm x 22.86 cm or 15" display with normal 4:3 aspect ratio). So you can leave the digitizer size as is. This makes the visual feedback REAL SIZE.
o San Diego: Sony VAIO laptop display size is 28.5 cm x 21 cm or 13.75" display with normal 4:3 aspect ratio). You can leave the size as is but thre will be a 7.5% size reduction. TO prevent this you could TWEAK the digitizer size as being 28.5 cm x 21 cm (thus the top 2 cm and the right 1.8 cm of the digitizer are not used). This makes the visual feedback REAL SIZE.
2b. Experiment settings
o Rightclick your experiment (PH2) >Experiment settings >Running Experiment >Trials
o Check Maximize recording window
o Click >Recording >Input Device
o Click Acquire <==This will update the sampling rate, min. pen pressure, resolution
CHECK: The sampling rate is 100 Hz. The resolution is 0.0005 cm. If not, you have the wrong driver or digitizer.
ALTERNATIVE SIZE SETTINGS THAT WE WILL NOT USE:
OPTION 2: Mapping of the left bottom part in real size.
o Settings >Select input device >Select Map Tablet to Recording Window
o Rightclick your experiment >Recording >Input Device >Acquire device settings
o To map the bottom left part of the digitizer INSIDE the recording window so the subject cannot move the pen towards the controls on the left and bottom:
o To set REAL SIZE visual feedback we can specify that the digitizer is 2.5 cm narrower and 6.5 cm less high than the previous display sizes. So what we win at the left and bottom margins, we loose at the right and top margins.
OPTION 3: Mapping of entire digitizer at reduced size.
o Settings >Select input device >Select Map Tablet to Recording Window
o Rightclick your experiment >Recording >Input Device >Acquire device settings
o To map the entire display within the recording window we have nto other option than to reduce the feedback because the displays are not much larger than the digitizer
o To map the ENTIRE DIGITIZER AT REDUCED REAL SIZE and have the entire digitizer mapped on the recording window inside the display. In that case, set the digitizer as is but ADD the extra sizes to the display size.
OPTION 4: Real Size Mapping of Entire Digitizer
o For the Wacom Intuos3 12x9 digitizer you will need a 20" display (which is >2.5 cm wider and >6.5 cm higher than the digitizer. For the Wacom Intuos 8x6 digitizer you will need a 14" display)
o Settings >Select input device >Select Map Tablet to Recording Window
o Rightclick your experiment >Recording >Input Device >Acquire device settings
3. QUICK TESTS to check the settings
3a. Range of data
o Start running a subject in the experiment
o Move pen so that the cursor on the screen goes from bottom left to top right of the specified digitizer area.
o Verify the cursor moves across the relevant part of the digitizer.
3b. Scaling of data and time
o Record the following trial
o Write a circle of 2 cm diameter (approximately) with a normal pen on paper.
o Make 5 overlapping circles with the pen at a rate of about 2 s per circle.
o Double-click on the trial just recorded.
o Verify the processed data chart in the y as a function of time graph that the amplitude is 2 cm and the duration of 5 circles is about 10 s. Repeat the same for the x as a funtion of time graph.
3c Accuracy of data and time
o Record the following trial
o Use a plastic ruler positioned at 45 degrees across the digitizer
o Lower pen, against the ruler, make a very fluent, middle fast movement without wobbling the pen and lift.
o Accept the trial
o Stop the experiment.
o Rightclick on the very trial >Test linearity >View all charts.
o Verify the Missing Sample Estimator graph as only points around 0 or 1 and no .5 or 2.
o Verify in the Results window (move the splitter) that the RMS sample error is around 0.005 cm.

TROUBLE SHOOTING
Why does the pen drawing on the tablet NOT fit the entire screen and how can I fix this?
ANSWER: When you connect a new Wacom digitizer or update to the latest Wacom driver, the default tablet settings may not be correct. You can acquire the correct driver setting in MovAlyzeR using the following the steps:
