Abstract
The present invention provides a haptic control device () for controlling a desired quantity via a touch-sensitive display screen () without providing any visual feedback. The device comprises a touch-sensitive display screen, a pressure measuring device, calculating means, adjustment means controlled by the calculating means, and a haptic actuator controlled by the calculating means. The pressure measuring device is configured to measure an amount of pressure applied by a user to the touch-sensitive display screen and a displacement of the applied pressure on the touch-sensitive display screen. The calculating means is configured to determine if the applied pressure exceeds a predetermined threshold value. If so, the calculating means controls the adjustment means to alter the desired quantity in dependence on the displacement of the applied pressure measured by the pressure measuring device, and also controls the haptic actuator to adjust surface friction of the touch-sensitive display screen in dependence on the displacement of the applied pressure measured by the pressure measuring device. The invention also provides a corresponding method of operating a haptic control device to control a desired quantity via a touch-sensitive display screen and an electronic device at least comprising such a haptic control device.
