Minimum Distance between Operating Elements for Multi-touch Appli-
cations
To guarantee smooth operation with multitouch applications, buttons and control elements
that should be operated at the same time must have the minimum clearance shown below
(depending on the estimated touch point).
The size of the buttons and operating elements directly affect the operability
of the application. Small operating elements should therefore be avoided.
