A process determines touch orientation of touches on a sense array of a touch-sensing device. The process obtains first touch data and second touch data of a conductive object proximate to the sense array at two temporally proximate times. The first and second touch data are then used to determine a first touch orientation, and the second touch data is used to determine a touch area and a provisional touch orientation. A touch orientation change is then determined as an absolute difference between the first touch orientation and the provisional touch orientation. The touch orientation change is compared with a threshold change, and the touch area is compared with a threshold area. In accordance with comparison results, the first touch orientation, the provisional orientation, or a weighted combination of them is designated as a second touch orientation corresponding to one of the two temporally proximate times.

Determination of touch orientation in a touch event

Apparatuses and methods of calculating a touch orientation of a touch data measured on a sense array. One method calculates the touch orientation by determining a major axis length of the touch, determining a maximum width of the touch in a first axis, and calculating an inverse trigonometric function using the maximum width and the major axis length. Another method calculates the touch orientation by determining a centroid position of the touch and a touch outline of the touch, calculating perimeter distances between the centroid position and the touch outline, and calculating the orientation using the largest distance value of the calculated perimeter distances and the centroid position. Another method calculates the touch orientation by calculating eigenvalues and eigenvectors.

Touch orientation calculation

A method, computer system, and graphical user interface for generating firmware code for a programmable integrated circuit are disclosed. Embodiments are directed to a configurable menu hierarchy which is displayed as part of a graphical user interface, and therefore may be configured on-screen by a user interacting with elements or regions of the graphical user interface. Once the hierarchy of the menu is configured, a data structure for implementing menu functionality associated with the displayed menu hierarchy may be automatically generated. Firmware may be generated based upon the data structure and stored within a programmable integrated circuit. The firmware may enable the programmable integrated circuit to implement the menu functionality external to the programmable integrated circuit using at least one component of the programmable integrated circuit. The menu functionality may operate in conjunction with at least one user interface device of the electronic device.
