Abstract: A method for image navigation on an electronic device is described. The method includes displaying an image. The method also includes detecting at least one contact with a touch sensor to obtain a first position. The method further includes obtaining an updated position corresponding to a contact movement. The method additionally includes determining a modified position by applying at least one scaling function based on the first position and the updated position. The method also includes moving the image based on the modified position.

Abstract: An electronic device configured for tracking multiple contacts is described. The electronic device includes a processor and instructions stored in memory. The electronic device receives a plurality of current contact locations for a plurality of contacts. The electronic device tracks the plurality of contacts, which includes calculating distance approximations between the plurality of current contact locations and at least one previous contact location and sorting the distance approximations to identify the current contact points. The electronic device also performs an operation based on tracking the plurality of contacts.
