Abstract
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.
