Assessing and/or optimizing capacitive touch accuracy

Hi, I'm looking for help assessing & optimizing capacitive touch accuracy.  We will be measuring touch accuracy across various hardware/software combinations.  Specifically, we will working with the apple iPad Pro & Apple Pencil 2 (capacitive touch), the Surface Pro 3 (resitive touch), and the Wacom drawing tablet (Wacom).  

The job will be to help create a scientific system (e.g., miniature experiments) so that we can test these aspects.

The goal is for us to optimize the capacitive touch precision in the apple products (specifically within our software) as compared to the other hardware/software combinations.  We have laboratory equipment that can help us in this experimentation and are open to purchasing additional equipment if the pricing is reasonable. I will then conduct the experiments using my setup via zoom meetings.  We can make adjustments live, troubleshoot together, and determine how to achieve these scientific goals.

Also, please write the first 4 numbers of Pi in the job description so I can identify who actually read this job description.

Lastly, I have a software development group that will be working on the optimization process. Please specify if you are interested in working on the best way to assess capacitive touch accuracy, if you can help with the optimization of our software, or both.

Thank you,
David
