The invention relates to a tongue sensor system which enables the user to utilise the tongues selectivity in a more optimal way. Specific functions or actions to be controlled, e.g. functions of a prosthesis can be allocated to specific sensors of the array of tongue sensors. Therefore, it is possible to predefine the function of different sensors so that sensors located where the tongue has a high selectivity is predefined to control or activate functions which are often used or requires high selection accuracy. The tongue sensors may be used directly to control devices, or the tongue sensors may be used indirectly to affect how other control systems should work. For example a control system for prostheses based on myoelectric signals may be affected by tongue sensor outputs so that pre-activation of specific tongue sensors causes the muscle control system to control different functions in dependence of the activated tongue sensor.
