Embodiment Construction

[0017]The Figures illustrate examples of an apparatus 10 comprising: a first surface electrode 2 and an arrangement 6 of second insulated surface electrodes 4; a display 32 configured to display an image; and a controller 30 configured to apply a varying potential difference 24 between the first surface electrode 2 and the arrangement of second insulated surface electrodes 4 in dependence upon the displayed image.

[0018]In use, one portion of the user's body contacts the first surface electrode 2 and another portion of the user's body, preferably a digit, contacts or comes close to contacting the second insulated surface electrode 4 presented on a face 12 of the apparatus 10. The two points of contact close a local electric circuit via the user's body.

[0019]Each second insulated surface electrode 4 has an associated electric field. The electric field produces a force that does not directly create a touch stimulus at the overlying digit of a user when the digit is stationary but does ...
