parts: hardware and software. Hardware serves to
complete the information collection and software to

converted into specific user command [3]. It is believed
that the Multi-touch key technology should include the
following major components: Multi-touch Hardware
Platform: These platforms have their own advantages
and disadvantages. Study of these platforms helps to
understand how to build interaction platforms of lower
cost, more convenient installation and more precise
target selection and to study a number of other
interactive technology unrelated to the platforms. The
Accuracy of Selection for Multi-touch Device Precision
choice technology, in fact is the detection of contact
tracing, and it has great significance on how to
accurately track and locate contacts to achieve the
freedom of gesture interaction. In particular, when the
target size is very small, how our fingers could
accurately locate the goal we want, is the content worth
deep study.
