A suspension system for a differential-pressure touch sensitive panel suspended over force sensors, for use in either fixed or mobile devices such as point of sales terminals, kiosks, laptops, monitors, PDAs, cell phones, UMPCs and more. In one embodiment, each side of the lens is encircled and supported by a looped string, monofilament or flexible wire, which is then looped around the back cover or base plate, forming a figure-8. The figure 8-loops bring the lens into a fixed state in the xy-plane without the addition of any friction causing physical contact. Other alternative implementations include continuous suspensions, bender suspensions and 3-dimensional force suspensions. Moreover, the present invention proposes the use of a flexible padding under the force sensors to allow the sensors to be slightly preloaded, which reduces the dependency on extremely tight mechanical tolerances.

Pressure compensation can be used to improve performance of force-sensitive touch screens. Changes in pressure, particularly transient, internal pressure changes in an electronic device due to an object applying force to a touch screen of the electronic device, can degrade force sensing performance of the touch screen. For example, when a finger presses a force-sensitive touch screen of a sealed electronic device, the applied force can increase internal pressure of the sealed electronic device until internal pressure can equalize. The increased internal pressure can cause a normal force to oppose the deflection of the touch screen, resulting in inaccurate force measurements of applied user force. In some examples, an electronic device including a force-sensitive touch screen can include a pressure sensor configured to measure internal pressure of the electronic device. The measured pressure can be used to compensate the amount of force measured by the force sensor.

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.

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 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.
