Hi, I'm looking for help assessing & optimizing capacitive touch accuracy across various hardware/software combinations. Specifically, we will work with the Apple iPad Pro & Apple Pencil 2, the Surface Pro 3, and the Wacom drawing tablet. 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 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 togeth...
