Abstract
Input device configurations are described. In one or more implementations, an input device includes a sensor substrate having one or more conductors and a flexible contact layer spaced apart from the sensor substrate. The flexible contact layer is configured to flex to contact the sensor substrate to initiate an input of a computing device. The flexible contact layer includes a force concentrator pad that is configured to cause pressure to be channeled through the force concentrator pad to cause the flexible contact layer to contact the sensor substrate to initiate the input. In one or more implementations, an input device includes a capacitive sensor assembly arranged in an array that is configured to detect a location of an object that is proximal to a respective capacitive sensor of the capacitive sensor assembly and a pressure sensitive sensor assembly including a plurality of pressure sensitive sensor nodes that are configured to detect an amount of pressure applied by the object against a respective pressure sensitive sensor node of the pressure sensitive sensor assembly.
