Systems and methods for input device audio feedback
View Patent ↗Systems, methods, apparatuses and computer program products configured to provide sound feedback for input devices are described. Embodiments take input from a digitizer, such as input using as stylus/pen, and produce sound feedback to enhance the user's input interface experience. Embodiments thus provide a user with a more realistic interface with an electronic device, emulating use of conventional writing implements.
