      abstract     = {There is growing interest in touchscreens displaying
                      tactile feedback due to their tremendous potential in
                      consumer electronics. In these systems, the friction between
                      the user's fingerpad and the surface of the touchscreen is
                      modulated to display tactile effects. One of the promising
                      techniques used in this regard is electrostatic actuation.
                      If, for example, an alternating voltage is applied to the
                      conductive layer of a surface capacitive touchscreen, an
                      attractive electrostatic force is generated between the
                      finger and the surface, which results in an increase in
                      frictional forces acting on the finger moving on the
                      surface. By altering the amplitude, frequency, and waveform
                      of this signal, a rich set of tactile effects can be
                      generated on the touchscreen. Despite the ease of
                      implementation and its powerful effect on our tactile
                      sensation, the contact mechanics leading to an increase in
                      friction due to electroadhesion has not been fully
                      understood yet. In this paper, we present experimental
                      results for how the friction between a finger and a
                      touchscreen depends on the electrostatic attraction and the
                      applied normal pressure. The dependency of the
                      finger–touchscreen interaction on the applied voltage and
                      on several other parameters is also investigated using a
                      mean field theory based on multiscale contact mechanics. We
                      present detailed theoretical analysis of how the area of
                      real contact and the friction force depend on contact
                      parameters, and show that it is possible to further augment
                      the friction force, and hence the tactile feedback displayed
                      to the user by carefully choosing those parameters.},
