Digitizer Requirements

The correct operation of FitalyStamp depends highly on the precision of the digitizer.

If your device has been used extensively with Graffiti and the Graffiti area is worn out by this usage, you may experience mis-taps with FitalyStamp as the digitizer will produce incorrect tap coordinates. Note that the single taps required by FitalyStamp are different in nature from the moves required by Graffiti: More precision is required for single taps as the averaging effect of moving across several points is not available.

Consequently, the use of FitalyStamp may reveal preexisting digitizer problems that were previously unnoticed in Graffiti usage. In particular heavy usage of Graffiti may have damaged the center left area, causing problems around the letters d and i, where most Graffiti gestures start.

You can use tools such as TealEcho or the freeware Graffiti Aid by Chris Crawford to check the condition of the digitizer. (If a digitizer is faulty, these tools may show an irregular or spotty line when drawing a straight line.) Check also for the absence of the so-called tap bug and for possible cures. If these fail, the only way to fix this problem is to have the screen repaired.

If you are experiencing digitizer problems, try to use the Sure Mode which you can select in the Operation Mode panel of FitalySetup. While slightly slower, the sure mode is often able to compensate for mild digitizer defects and deliver a better precision. (On the other hand, if your digitizer is in perfect condition, the normal mode allows faster entry.)

On this subject, see also the article by Hannes Frischat "What to to about the tap bug" in the Fitaly FAQ.


Using Half-Cells

The Half-Cell Usage panel of FitalySetup contains options allowing the uses of half-cells instead of sliding for digits and punctuation marks, and also for arrows and accents. If you are use these options and have one of the older models, you should adopt a higher placement of the FitalyStamp, immediately below the application screen. Below is an explanation of what happens.

Consider first how the Palm screen is normally divided. Vertically, there are 220 pixel positions numbered 0 to 219:

 HeightPixels Usage
 1600 - 159Application Screen
 4160 - 163Unused
 56164 - 219Graffiti Area

The FitalyStamp height is also 56 pixels (five rows of 10 pixels and six separators) so it is quite natural to position FitalyStamp at the bottom, just on top of the Graffiti Area. This position will work for all but those who opt for the half-cell advanced option.

The reason is that, for older models, the Palm digitizer does not really distinguish between screen positions 215, 216, 217, 218, 219 and returns the value 215 for any of these positions. (This is true for older Palm models but has been corrected on newer models such as the Vx, m500, m505, IIIc, and the Sony Clié.)

Here is what happens:

You tap on the red dot to get a 9. With a correct digitizer, the distances to the corner would be delta X = 2 and delta Y = 1, and this would be interpreted correctly as a 9. But with the digitizer error, everything happens as if you had tapped on the blue dot: the Y coordinate becomes 215 and the delta Y = 4 is now greater than the delta X so that you get the "/".

If you are using half-cells, you can circumvent the digitizer error by placing FitalyStamp higher, taking advantage of some or all of the four unused pixels 160-163. For those who dislike having a higher position, one solution is not to use half-cells.

Another solution is to use taps on the right part of the cell to get the lower triangle. For example, if you tap well on the 9 or even to the right of the 9, the delta X will be larger than the delta Y, in spite of the digitizer error. However, this will not work to distinguish arrows from accents.


Notes on the Handspring Visor

When installing FitlyStamp on a Handspring Visor, it is recommended that you place FitalyStamp slightly higher than the top of the Graffiti area. You can go half-way into the unused area between the application screen and the Graffiti area. (You can even cover the full unused area.)

Note also that FitalyStamp's keyboard toggle covers the Visor's contrast adjustment spot. But you can adjust contrast form the FitalyStamp menu.



The current release of FitalyStamp3.prc, dated 2004-07-20, works with Palm OS versions 3 and 4; the FitalyStamp3Os5.prc release, also dated 2004-07-20, works with Palm OS version 5.

FitalyStamp works with essentially all applications. Known incompatibilities exist with the following applications:

Partial incompatibilities exist with the following applications:

  • TealEcho
— incompatibility with sliding
  • EVEdit
— incompatibility with the Graffiti echo feature
  • TextPlus
— incompatibility with the Graffiti echo feature

This list is based on the releases dated 2004-07-20 and may or may not apply to later releases.


Instruction for the Demo version

The demo version includes Adobe Acrobat pdf files with gray-scale versions of the FitalyStamp overlays. The available FitalyStamp models are shown below:

The corresponding pdf files are as follows:
TungstenFitalyStamp.pdf Clie188FitalyStamp.pdf
PalmVFitalyStamp.pdf Clie198FitalyStamp.pdf
m100FitalyStamp.pdf Palm3FitalyStamp.pdf
Samsung500FitalyStamp.pdf Kyocera7135FitalyStamp.pdf

You will need to open the pdf file that applies to your Palm handheld and print FitalyStamp. Before you print from Acrobat, make sure that you select Actual Size (100%) and deselect "Fit to page" and "Annotations" in the print dialog.

Then place the overlay on the Graffiti area with the top aligned on the top of the area and secure it by some method of your choice: For example, use scotch tape, print it on a mailing stamp, put a transparent foil on top, print on HP's restickable stickers or some equivalent. (One way to position a label is to print first on a full page and then affix your sticker to the page and print again.) You can also cut a larger frame and tuck some of it under the sides of the Palm organizer.

The vertical position of the FitalyStamp overlay is not too critical as you can adjust it from the Adjust Position dialog of FitalyStamp. Actually, you can go as high as the bottom of the application screen and some of you may want to use it that way. You will also be able to adjust for horizontal position (but not for a rotation).
