A user may provide finger press input to a surface such as a touch sensitive input surface. The input surface may be formed from a two-dimensional touch sensor overlapping a display of an electronic device. The electronic device and an associated device such as a finger-mounted device may form a system for gathering the finger press input from the user. A sensor may be used in monitoring when the finger-mounted device and a user's finger in the device approach the input surface of the electronic device. In response to detection of the finger near the input surface, actuators in the finger-mounted device may squeeze the finger inwardly to cause a finger pad on the finger to protrude outwardly towards the input surface, thereby softening impact between the finger and the input surface. The electronic device may also have an array of components to repel the finger-mounted device.
