Abstract
Methods and systems are provided for enabling a user to interact via touch input with a document displayed on an electronic device such as an electronic reader. The system determines a measure of the size or shape of a touch object, and accordingly associates input gestures with different actions. A user can therefore use finger touch input for page turns and stylus touch input for electronic inking operations, without having to toggle between modes. The associated actions can be modified with a second touch event, such as a thumb touch in a corner of the display area. Infrared touch systems are well suited to implementing the inventive methods in electronic readers because they do not require the presence of any high refractive index layers in front of the display.
