<p>The invention relates to an input device (1) for a home appliance for operation with a finger (4), comprising
a) sensitive keys (11 - 22) arranged below a surface in a two-dimensional array (2),
b) wherein a key voltage based on the nearness of the finger (4) is genetatable by each sensitive key (11 - 22) dependant on the distance from the key and the size of the finger (4),
c) wherein in a detection unit (8) all key voltages are comparable and
d) wherein in the detection unit (8) the position of the finger (4) is detectable. Furthermore, the invention relates to a method for data input for a home appliance for operation with a finger (4), especially for an input device according to the invention,
a) with sensitive keys (11 - 22) arranged below a surface in a two-dimensional array (2),
b) wherein a key voltage is generated based on the nearness of the finger by each sensitive key (11 - 22) dependant on the distance from the key and the size of the finger (4),
c) wherein all generated key voltages are compared,
d) wherein the position of the finger is detected,
e) wherein preferably the detection is repeated after a predefined time span and/or
f) wherein preferably a movement of the finger (4) is detected.</p> |
