Interaction device

摘要

The invention relates to an interaction device (1), comprising
a) a first input unit (20) with a first sensitive surface, especially a touch display, and a first sensor unit,
b) a second input unit (2-12) with a second sensitive surface and a second sensor unit,
c) wherein the second input unit (2-12) is used for protection of the first input unit (20), especially against overheating and/or mechanical damaging. Furthermore, the invention relates to a glass ceramic hob (22), especially induction cooking hob, with an interaction device (1) according to the invention
a) wherein preferably the interaction device (1) is arranged in a side and/or edge area of the glass ceramic hob and/or arranged at the lower surface of the glass ceramic hob (22) and/or
b) wherein preferably the glass ceramic hob comprises a fan for ventilation. Furthermore, the invention relates to a method for protection of an input unit, preferably for an interaction device and/or a glass ceramic hob according to the invention, comprising
a) a first input unit (20) with a first sensitive surface, especially a touch display, and a first sensor unit,
b) a second input unit (2-11) with a second sensitive surface and a second sensor unit,
c) wherein the second input unit protects the first input unit,
d) wherein after an input has been detected by the second input unit, especially after a preselected threshold value has been exceeded,
e) the input value is compared with at least one preselected threshold value,
f) wherein the at least one threshold value is preferably larger than a threshold value generated by the press or the touch of a finger,
g) wherein after exceeding the at least one threshold value,
g1) the first input unit (20) is turned off and/or
g2) the heating energy for the glass ceramic hob, especially the induction current, is turned off to decrease the temperature and/or
g3) an alarm is generated, especially an optical or acoustical alarm, to warn the operator and/or
g4) the speed of the fan is increased to decrease the temperature.
