MOTO's simple touchscreen stress test
Sunday, January 10, 2010 at 5:52AM MOTO labs has posted a good article discussing touchscreen accuracy. They describe a simple line-drawing test you can do on touchscreens: DIY Touchscreen analysis. The basic ideas is to slowly draw diagonal lines in a drawing program, and then watch how linear the result is. They also look at edge performance.
Of course this is just one part of the picture -- there are other measures of accuracy and responsiveness (this doesn't say much about touch-down/lift-off accuracy, for instance). And as MOTO points out, the touch sensor is just one factor among many that contributes to quality. They sum up with some dos and don'ts:
MOTO has worked with capacitive touch interfaces for more than 15
years, and here are some essential dos and don’ts for anyone entering
the field:
- Don’t skimp on materials. With touchscreen hardware, manufacturers
get what they pay for — and consumers will notice the difference.- Allow ample time to develop your algorithms. Don’t treat
touchscreen algorithms as an element of component sourcing; for best
results, create a distinct touch development track under your own roof
to make sure your products are both responsive and accurate.- Closely integrate touchscreen hardware, software, and user
interaction development, and do so as early as possible in the product
development process. Never treat them as separate tasks.

I clicked on the DIY touchscreen analyses link but it forwarded me to a broken page on Cisco?
