Android phone Touchscreen Sampling rate - signature capture
Posted on 2011-03-10
we have a call centre application that has a remote access service that I can update calls from a mobile device. As part of our call update we can also capture signatures, we would like to use something like a Samsung Galaxy S to do so (reasonable compromise in terms of price vs performance) but have an issue with the quality of the signature in that they are not smooth, they have lines instead of curves - picture trying to draw an S but ending up with a 5 etc.
This issue is not apparent on iPhone 3Gs or 4 (and as the 3Gs only has a 600Mhz CPU doesnt seem performance related) but we can't justify the additional cost of these devices (will make the project cost £1000's more).
I wonder if there is any way of increasing the sampling rate on the Android device so that it collects more x/y co-ordinates and therefore produces smoother signatures?
The call centre signature app is developed in Java and the developer is unable to assist, having got to the point of testing that the iPhone works but any Android devices I've tried (HTC Desire HD, Motorola Milestone & Envy as well as the Samsung). So I think the only option I can now pursue is if there is any way to make the Android phones sample for touch screen inputs more often. I'm hoping somebody knows of a tweak app or hidden setting that will allow me to change the sample rate.
I have searched for how to achieve this but aside from another couple of people asking a simliar question can't find any resources for this.
Any pointers greatly apprectiated - either to a way of setting the sampling rate or perhaps a way of putting the question to a more suitable Google / Android development group.
Thanks in advance!
