My project involves tangible user interfaces. I have developed a game in which the input will be any squeezable object. The input will have force sensors in it & the user's squeeze will be converted to electrical signal & characters in the game will move accordingly. Mode of squeeze is by...

Thanks for the reply. My explanation for stating that maximum stress is near the surface goes like this. The pressure is a function of the force applied divided by the area it is spread over. And if you think about it, any cross section of the ball between the two points must have the same...

Hi, I have two squeeze balls with pressure sensors inside them. One squeeze ball(Ball A) has a sensor placed at the center while the other one(Ball B) has two sensors, placed very close to the two opposite surfaces. These squeeze balls act as an input to a game developed. Depending upon the...

Hi, After reading your post, I read few other articles. Now I have a better idea about the topic. Thanks a lot for patiently replying to my posts. The only part I am unclear now is regarding the forces acting. I know, as u said, I need to think about the stress & not force. But still I would...

It's a small left to right obstacle avoiding game( we will be improving the game in the future). Our main focus is its application which is to help people by making their rehabilitation from hand injuries much more entertaining. Patient's hand must be utilized to the maximum while playing the...

Hi, Thanks a ton for the reply. Now I have got some idea to start.

Hi, Is there a way to prove that the maximum force is felt under the finger tips(which I believe is correct) while squeezing a foam ball? I would like to write equations to support my point. As mentioned before, the ball will be squeezed using the fingers & palm of the hand.

it could be under the fingers or may be at the center. But I am thinking about how to theoretically prove by writing equations of force & displacement & get the locations of maximum force.

Hi, Thanks a lot. Let me go through it.

Hi, Thanks a lot for the advise. I am planning to do such testings in future. But right now I am looking for some equations & theoretical knowledge regarding the force distribution when a ball is pressed. Once I can figure out theoretically the locations, I will test it by placing sensors &...

Hi, Sorry. I missed it. Thanks. We are mainly interested in the above mentioned first method of squeezing i.e. squeezing the ball between the fingers & palm of the hand. So in this method, where could be the pressure area?

Hi Astronuc, Thanks for the reply. I would like to know how to find out the areas where maximum force/pressure is felt while squeezing. Let's take an example of a stress ball. So for a spherical ball, when we squeeze, which are the areas where maximum force is felt? How do i theoretically find...

Hi, I am new to this forum. I am currently working on a project in the field of tangible user interface. I am developing a game in which a pressure sensor squeezable ball is the input controller. I am done with the game. Now I need to design a squeeze ball. My next aim is to find out the...
