摘要:
A display includes a light-transmissive planar member with side edges and opposing surfaces. A plurality of light sensors are disposed along at least two of the side edges of this planar member. These light sensors are disposed to detect light moving through the light-transmissive planar member by internally reflecting off the aforementioned opposing surfaces. A control circuit detects a position of a light-emitting stylus with respect to the display by using the plurality of light sensors to detect light from the light-emitting stylus that moves through the light-transmissive planar member via the aforementioned internal reflections. By one approach the side edges the light-transmissive planar member are inclined at other than a perpendicular angle with respect to the aforementioned opposing surfaces.
摘要:
An electronic device, computer-readable medium and method provide for line smudging in electronic drawing. The electronic device has a touch sensitive display screen that is responsive to user touch and stylus input. A graphics module is operable to render a line on the touch sensitive display screen in response to motion of the stylus. If a trajectory of the touch input intersects with the line within a set time period after the line is rendered, the line is replaced by a representation of a smudged line. The electronic device may be controllable by instructions stored on a computer-readable medium.
摘要:
A method includes displaying a selectable feature on a touch-sensitive display of an electronic device, detecting a touch at a location within a target area associated with the selectable feature, and adjusting the target area based on a contact area of the touch and a magnitude of at least one signal when the touch is detected.

A method includes detecting a touch on a touch-sensitive display, determining a time of a display update of the touch-sensitive display, and adjusting a scanning rate of scanning electrodes of the touch-sensitive display based on the time of the display update.
