a key feature in providing a good user
experience for touch enabled devices is
the performance of the touch sensor
itself
if the touch sensor performs poorly
using the product will not feel right no
matter how well the rest of it works
with a well-performing touch interface
the user will have a much more enjoyable
first hand experience in using the
product
opto fidelity touch panel performance
test system is a turnkey solution for
automatic measurement of key performance
metrics from a touch panel
test system consists of accurate robotic
movements combined with touch sensor
actuation for one two and multiple
fingers
a key feature of the system is the
software package
that executes the testing process
accurately and consistently
all touch sensor activation is done
automatically including taps swipes
zooms and other gestures
system changes activation methods
automatically so the complete test
process can be executed without operator
interaction
optofidelity touch panel performance
test system can be used to test both
pair touch sensors or touch performance
of touch-enabled devices such as
smartphones and tablets
for convenience test process is divided
into separate sections for all the
features that are tested
different sections exist for single
finger and multi-finger testing as well
as testing for coordinate accuracy touch
latency and gestures
test software is highly configurable via
test parameters or with optional test
application development tools
it is easy to perform a quick test with
a small number of test points as well as
an extremely thorough test process with
high test point count
the system features an interactive
report that shows the measured values as
well as the requirement limits and
provides pass fail criteria for each
test
report is html based and can also be
accessed over the network
test system includes optofidelity pid
for high accuracy measurements of touch
latency directly from the touch
controller chip interrupt
i squared c or sbi communication with
the controller chip can be freely
customized via driver software that can
be changed on the fly
so testing panels with virtually any
controller chip can be supported
