Hello,
I am currently working in an Alzheimer's related researching where we are utilizing the force (pressure) data from the Apple Pencil.
While we are able to get a range of the force values (0 - 4.2), we do not know the actual unit of this pressure. I have gone through the documentation but I did not find any mention about the unit of the touch.force parameter.
What is the unit of this touch.force parameter?
I also wanted to ask about being able to capture other information from the apple pencil like accelerometer data, gyroscope data etc. The more data we are able to capture from the pencil the better, so that the data can be used for future studies about Alzheimer's Disease. Currently I am using the pencil to capture the following data: -
- Force
- Location (coordinates)
- Altitude angle
- Azimuth angle
- Azimuth Unit Vector
- Perpendicular Force (calculated as per documentation)
- Major Radius
- Tap Count
If there is anything more that I can capture via the apple pencil, it would be great for future studies.
Additionally, a little about the application, we are having users draw a clock on a canvas and collecting that data. I am using a PKCanvasView for the canvas, and if there is any data that I can collect via the canvas, I would love to know that as well. As of now, I am using the PKCanvasViewDelegate to get data, but if there is anything more that I can collect, that would be great.
Thank you for your time
