A hybrid touch-screen display that integrates force-based touch-screen technology with any one from among a group of projective capacitive, surface capacitive, resistive, digital resistive, SAW, IR, APR, DST, optical and electromagnetic touch-screen technologies to provide an ability to compensate for non-perfect force transfer. An alternate implementation is also disclosed that employs a single force sensor for relative force measurement in a system in which force is traditionally not measured, here a water dispenser unit. This allows compensation for varying static loads, run-time calibration, and filtering of extraneous loads through firmware.

The present invention relates to a touch screen, and particularly to a pressure-sensitive touch screen and an electronic device. The present touch screen comprises a substrate which has an elastic deformation performance and is used by a user to operate and a strain sensor which is used for detecting lateral deformation of the substrate and is fixedly arranged at a peripheral location of a lower surface of the substrate, and further comprises a pressure bearing plate, wherein the pressure bearing plate is fixedly arranged at an upper surface of the substrate, and the location where the side edges of the pressure bearing plate are projected onto the strain sensor is located at a middle location of the strain sensor. Also provided is an electronic device containing the pressure-sensitive touch screen. By way of detecting a lateral deformation amount of the substrate, the present invention thus recognizes a touch location and a touch pressure value, provides a pressure-sensitive operation function for a user and can adapt to different input methods, without being limited by the touch form.

The invention relates to a user interface comprising a touch-sensitive touch screen, a special token being placed thereon. Said token comprises two disks which are interconnected by means of a ball bearing and which enable a rotation to be directly recorded by means of the token and by a rotation controller. The guiding of the rotation by the ball bearing enables the input object to have a particular haptic quality. Said ball bearing enables values to be modified rapidly up to a free running state when the upper element is accelerated and the rotation is continued once the user releases the input object based on the low friction resistance in the ball bearing, but also very precise, small adjustments in which the token provides a step-by step modification and/or screening of the rotation, such that the user receives, for each modified unit, a discrete haptic resistance via the finger-tips. Any parameters can be adjusted in a fast and efficient manner due to the tokens. The structure of a technical system can be reproduced on the touch screen, the parameters of corresponding elements of the technical system being visualized and can be modified by annular elements.

The present invention discloses an electronic device that uses separate surfaces for input and output. One of the surfaces (e.g., the bottom) includes a force-sensitive touch-surface through which a user provides input (e.g., cursor manipulation and control element selection). On a second surface (e.g., the top), a display element is used to present information appropriate to the device's function(e.g., video information), one or more control elements and a cursor. The cursor is controlled through manipulation of the back-side touch-surface. The cursor identifies where on the back-side touch-surface the user's finger has made contact. When the cursor is positioned over the desired control element, the user selects or activates the function associated with the control element by applying pressure to the force-sensitive touch-surface with their finger. Accordingly, the electronic device may be operated with a single hand, wherein cursor movement and control element selection may be accomplished without lifting one's finger.
