I am new to the forum. I am currently working on a project in the field of Tangible User Interface. I am developing a game with input from a squeezable pressure sensor ball. I am done with the software part of the game. Now I need to design & implement the best possible pressure sensor squeezable ball.
Currently for the testing purpose, I have placed the sensor at the center of a foam ball. My next aim is to find out the best possible location & combination of sensors so that the user’s fingers are utilized to the maximum.
I am using Flexiforce pressure sensors interfaced with PC using phidget interface kit & adapters. I did a small research on this topic. All I could get was that the sensors could be placed on a core cuboid & then place it at the center of a squeeze ball. I am on the look out for new ideas.
Any advise regarding this will be highly appreciated. Thanks in advance.
Since force can be exerted anywhere on the ball, a pressure sensor is likely your best bet. This means however that the sensor will need to be enclosed in a ball so that air does not escape.
The alternative is really what you are doing by using multiple sensors around a core.
A 3D force sensor is ideal, but it’s a hemisphere as opposed to a complete sphere.
@CBenson… Thanks a lot for the reply. I am not going forward with that cuboid core concept. I believe if I place the sensor at the center, the squeeze sensitivity will be minimum. So I am planning to place sensors close to the surface of the ball. I am confused about the position as well as the number of sensors to be used. Appreciate if you could throw some light on these issues.
@KM6VV… thanks for the tip. I am advised to go ahead with flexiforce sensors.
