Abstract
A proportional force input apparatus for an electronic device includes a mechanism operable by a user of the electronic device, such as a stylus inserted into a spring-loaded socket of the device. The mechanism provides a tactile feedback to the user proportional to a force applied by the user. A variable strength sensor detects the force applied by the user to the mechanism and converts this to an electrical signal proportional to the force applied by the user. A processor operates to input the electric signal from the variable strength sensor and provide force information to an application running on the electronic device. Optionally, a second sensor can detect rotation of the stylus. As a result, a stylus can be used to provide vector information to an application such as a game.
