Method for operating a touch sensitive user interface

摘要

A method for operating a touch sensitive user interface is provided. The touch sensitive user interface comprises a touch sensitive surface (3) and at least two force sensitive sensors (15-66). The touch sensitive surface (3) is configured to provide a touch information indicating touch positions (6, 8) of at least two concurrent touches (5, 7) on the touch sensitive surface (3). The at least two force sensitive sensors (15- 66) are mounted at the touch sensitive surface (3) at different predetermined locations (11-14). Each of the at least two force sensitive sensors (15-66) is configured to generate a corresponding force information depending on a force being exerted on the corresponding force sensitive sensor (15-66). According to the method, the touch positions (6, 8) are determined based on the touch information and the force information is received from the at least two force sensitive sensors (15-66). Based on the at least two touch positions (6, 8), the force information from the force sensitive sensors (15-66) and the predetermined locations (11-14) of the force sensitive sensors (15-66) a corresponding touch force is determined for each of the concurrent touches (5, 7).

1. A method for operating a touch sensitive user interface, the touch sensitive user interface comprising a touch sensitive surface and at least two force sensitive sensors, wherein the touch sensitive surface is configured to provide a touch information indicating touch positions of at least two concurrent touches on the touch sensitive surface, wherein the at least two force sensitive sensors are mounted at the touch sensitive surface at different predetermined locations, wherein each of the at least two force sensitive sensors is configured to generate a corresponding force information depending on a force being exerted on the corresponding force sensitive sensor, the method comprising the steps of:
determining the touch positions of the at least two concurrent touches on the touch sensitive surface based on the touch information, receiving the force information from the at least two force sensitive sensors, determining a subset of the at least two force sensitive sensors, the subset comprising a force sensitive sensor indicating a lowest force value of the at least two force sensitive sensors and a force sensitive sensor indicating a highest force value of the at least two force sensitive sensors, and determining for each of the at least two concurrent touches a corresponding touch force based on the at least two touch positions, the force information from the force sensitive sensors of the subset, and the predetermined locations of the at least two force sensitive sensors.
