Touch sensitivity is enabled using a touch system that comprises a panel configured to conduct signals, e.g. by TIR, along detection lines across a touch surface. A signal processor operates to generate data samples indicative of transmitted signal energy on parallel detection lines at a number of different angles across the touch surface; process the data samples for generation of interpolated Fourier coefficients at grid points in a regular grid in a Fourier domain; and operate a two-dimensional inverse Fourier transform on the interpolated Fourier coefficients so as to generate an interaction pattern for the touch surface. The interpolated Fourier coefficients are generated sequentially for individual groups of grid points. Each individual group comprises grid points that have equal distance to an origin in the regular grid, e.g. grid points that are mapped onto each other by one or ore lines of symmetry in the regular grid. The group-based processing may improve processing speed and/or reduce the need for data storage.

According to one embodiment, an image processor includes: a detector; a calculator; and a corrector. The detector calculates a state signal indicating whether or not an operation is being performed on a projection surface where an image is projected. The calculating is based on information relating to the projection surface. The calculator calculates a correction parameter based on the state signal and the information relating to the projection surface. The corrector generates a corrected image based on the correction parameter and an image to be processed.

Detecting potential damage to a touch sensitive display of an electronic device as a result of contact with one or more other objects. Different characteristics associated with contact of the display by object(s) can be determined. Based upon one or more of these characteristics, the electronic device can determine if potential damage to the display is occurring. If so, the electronic device can trigger an alert warning of the potential damage. The characteristics can include the number of contacts/time, the frequency of contacts, the duration of each contact, the area of contact, the number of simultaneous contacts, and/or the intensity of the contact(s). Other factors indicating that the electronic device is not in use, such as the light intensity proximate to the electronic device, the orientation, movement, and/or location of the electronic device, can be detected to confirm that the alert should be issued.
