Abstract

Techniques for providing directional force induction in a handheld device for use in, e.g., personal navigation applications. In an exemplary embodiment, a magnetic element is provided on a mechanical support fixedly attached to a chassis of the handheld device. One or more conducting coils surround the support. Current is generated in the one or more conducting coils to accelerate the magnetic element relative to the support, causing a tactilely perceptible force to a user of the handheld device due to the recoil of the chassis from the movement of the magnetic element. In an exemplary embodiment, passive movement of the magnetic element due to, e.g., physical jostling of the handheld device, may be used to deliver energy back to the system for energy harvesting.

Description

technical field [0001] The present invention relates to force sensing, and in particular, to force sensing in handheld devices. Background technique [0002] Handheld devices such as personal digital assistants and cellular phones are very popular in the consumer electronics market today, combining portability with a rich feature set provided by increasing hardware and software capabilities. To provide users with a multimedia experience, the handheld devices described above can transmit audio, video, and tactile sensations. Haptic sensations may include vibration, torque, directional impulse, and / or any other force that a user can perceive through contact. Although techniques for generating tactile sensations are well known in the art, such techniques are not necessarily suitable for integration in handheld devices where low weight and low power consumption are particularly required. Furthermore, existing technologies may not provide the ability to fine-tune the haptics pe...
