Abstract

Technologies are generally described that relate to managing and/or generating sensor data. An example method may include receiving output data generated by a pressure sensor. The method may also include determining surface data, indicative of a surface type associated with a force applied to a surface of the pressure sensor, based on the output data. Furthermore, the method may include adjusting the output data based on the surface data to facilitate generating adjusted output data indicative of an adjusted pressure value generated by the pressure sensor.
