Are the motions binary?

hi all!

i am new here and never programmed a space mouse before.
for my project i have to check out a simple question:
are the movements of the space mouse binary?
So if you turn the mouse slightly to the right, are there signals (which can be read out), how much i turned it right? or is there just a threshold to detect a movement to a direction?

greetings from austria!

The device produces values generally in the range from -512 to 511 along each of the 6 axes, simultaneously, proportional to the amount you push/pull/twist it.

thanks for the very fast answer!

now i can ask some further questions

is there a datasheet about the lenght of the possible movements?
as example: i can rotate the mouse +/- 5 degrees?

the generall idea is to evaluate forces over the space mouse signals...
also the stiffness of the inner springs would be interesting!

All the various models will differ in that regard. Even different instances of the same model may differ. The device isn't a sensor. OTOH, you can be fairly certain that a single instance you have will be fairly consistent over time, if used in its normal mechanical range. There are definitely non-linear characteristics as you get toward the edges of movement.
