摘要： The present invention provides a method (200) of entering characters into an electronic device (100). The method comprises receiving a number of scribed stroke samples (207) from a touch sensitive tablet (105) of the device, the scribed strokes corresponding to lines of one or more characters. Determining a character entry height (221) of a character entry scribing region (180) of the tablet dependent on the received scribed stroke samples. Determining a character entry speed for the character entry scribing region of the tablet dependent on the received scribed stroke samples (217). Scrolling the character entry scribing region on a display (105) of the device depending on the character entry speed.

摘要： According to one aspect of the invention there is provided a method (20) and electronic device (1) for determining orientation and recognition of handwritten characters scribed on touchscreen (5). The method (20) includes receiving (22) the hand written character and then normalizing (23) the character to provide a scaled character that fits within a defined boundary. The scaled character comprises at least one line and a step of identifying (24) the lines of the scaled character as a vector is effected and thereafter a step of rotating (26) rotates the scaled character from an initial orientation to a final orientation through a plurality of discrete orientations. A step of calculating (27) then calculates, for each of the discrete orientations, magnitudes of co-ordinate components of each vector and then a summing step (28) then sums, for each of said discrete orientations, the co-ordinate components to provide a summed co-ordinate component for the scaled character at a corresponding discrete orientation. An assessing step (31) then assesses each of the summed co-ordinate components to determine a suitable orientation of the scaled character.
