Best possible shape for the input controller?

[Anuroop]

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 placing the object between 4 fingers & palm of the hand.

I am trying to place the sensors at maximum stress points in the input. Considering all these, what could be the best shapes(sphere or cylinder or anything) for the input? The user's squeeze must be efficiently translated to the game character's movement.

The expression "The user's squeeze must be efficiently translated to the game character's movement." doesn't make a lot of sense to me. You can have any efficiency you want just by changing the "gain" between the sensor and the movement of the character.

What other factors are important? For example how do you plan to compensate for the strength of the player (children vs adults)?

PS Why not use an input device that looks like a pair of nut crackers...

They use leverage to maximise (magnify) the applied force.
