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.
