A device comprised of at least a pair of accelerometers and a tilt sensor mounted in fixed relation to a datum plane defining surface (sole of a shoe) may be used for extracting kinematic variables including linear and rotational acceleration, velocity and position. These variables may be resolved into a selected direction thereby permitting both relative and absolute kinematic quantities to be determined. The acceleration is determined using a small cluster of two mutually perpendicular accelerometers mounted on a shoe. Angular orientation of the foot may be determined by double integration of the foot's angular acceleration (which requires a third accelerometer substantially parallel to one of the two orthogonal accelerometers). The two orthogonal accelerations are then resolved into a net horizontal acceleration or other selected direction which may be integrated to find the foot velocity in the selected direction. The average of the foot velocity corresponds to the subject's gait speed.

A solution for automatically activating different audio transducers of a mobile communication device based upon an orientation of the device. In the solution, a series of speaker/microphone assemblies can be positioned on the device, such as positioned near an earpiece and positioned near a mouthpiece. Different speaker/microphone assemblies can also be positioned on the front of the device and on the back of the device. The solution can automatically determine an orientation for the device, based upon a detected direction of a speech emitting source and/or based upon one or more sensors, such as a tilt sensor and an accelerometer. For example, when a device is in an upside down orientation, an earpiece microphone and a mouthpiece speaker can be activated. In another example, an otherwise deactivated rear facing speaker can be activated when the device is oriented in a rear facing orientation.

The invention provides a digital picture frame that allows a user to edit a displayed picture using simple and intuitive controls. Modifications to an image may be stored by the digital picture frame so that the digital picture frame may later display the edited or modified version of the picture rather than the original version. A user may edit a picture using mechanical controls (e.g., knobs, switches, slider-bars, wheels), sensors (e.g., a position sensor, a tilt sensor, a microphone, a light sensor), a voice recognition module, and/or a touch screen. A digital picture frame may identify a user and based on the user's identity (e.g., the user's preferences or permissions), may display pictures to the user. Further, different users may modify a picture in different ways, so that two different users may view two different versions of the same picture.

System and method for view navigation and magnification of the display of hand-held devices in response to the orientation changes along only two axes of rotation as measured by sensors inside the devices. The view navigation system is engaged and controlled by a single hand which simultaneously presses two ergonomically designed switches on both sides of the hand-held device. In other embodiments, the system engaged into the view navigation mode in response to an operator command in the form of a finger tap, or a voice command, or predefined user gestures. The response curve of the view navigation to sensed changes in orientation is dynamically changing to allow coarse and fine navigation of the view. Various methods are described to terminate the view navigation mode and fix the display at the desired view. Miniature sensors like accelerometers, tilt sensors, or magneto-resistive direction sensors sense the orientation changes. The system can be added to an existing hand-held device via an application interface of the device.

A tilt-compensated electronic compass can be realized by calculating rather than measuring Earth's magnetic field component Z in a direction orthogonal to the two measurement axes of a 2-axis magnetic sensor. The orthogonal component Z can be calculated using a stored value for the Earth's magnetic field strength applicable over a wide geographic region. The calculation also requires using measured field values from the 2-axis sensor. Once Z is known, and using input from a 2-axis tilt sensor, compensated orthogonal components X and Y can be calculated by mathematically rotating the measured field strength values from a tilted 2-axis sensor back to the local horizontal plane. Thus, a very flat and compact tilt-compensated electronic compass is possible.

Character data including an image generation program, image data, a sound program, and sound data, which are previously determined for each of characters used in a game, is stored in a game device 10. A controller 12 having a built-in tilt sensor 12c is connected to the game device, and operated by a player performing a tilt operation. The image generation program and the sound program concurrently process the image data and the sound data, respectively, using the same tilt data output from the tilt sensor. As a result, an image and sound of the character are concurrently changed in accordance with the tilt operation of the controller. Thus, it is possible to provide the game device enhancing the realism and the staging effects of the game.

A mobile terminal in which the user can manipulate the pointer easily without keystrokes or any pointing device. When the select button of an input unit is depressed, a tilt sensor provided with an accelerometer detects the tilt of a mobile terminal from a reference angle. Based on the tilt of the mobile terminal, a processor calculates the moving direction and speed of the pointer to move the pointer on a display. If the degree of the tilt increases, the pointer movement is accelerated. On the other hand, if the degree of the tilt decreases, the pointer movement is deaccelerated. When the pointer reaches an activate button to activate a desired application program, the pointer movement stops by returning the tilt of the mobile terminal to the reference angle. Upon release of the button, the application program is executed. That is, the pointer movement on the display screed can be controlled in such a manner that a marble is rolled on a plate according to the degree of the tilt of the plate.
