Abstract: Touch-based input devices, such as a stylus, can receive tactile input from a user. The tactile input functions can be performed by a touch sensor, such as a capacitive sensing device. A touch sensor can be integrated into a stylus in a low profile form. Tactile input can be received at the user's natural grip location. Furthermore, the stylus can effectively distinguish between tactile inputs from a user and disregard sustained tactile inputs that are provided while the user simply holds the stylus at the user's natural grip location.

Abstract: A stylus or other tactile-based input device can receive different types of tactile input from a user. The tactile input sensing functions can be performed by a touch input sensor, such as a capacitive sensing device, and a compressive force sensor, such as a capacitive gap sensor. A touch input sensor can be integrated into an input device in a low profile form and overlap the compressive force sensor so that both touch input and compressive force input can be detected in the same regions of the stylus. Both types of tactile input can be received at the user's natural grip location.

The predetermined light sources can be disposed in asymmetric substantially linear or two-dimensional patterns. The predetermined light sources also can output waveforms modulated in accordance with one or more signature modulation characteristics. The predetermined light sources also can output light at different signature wavelengths.

Abstract: The disclosed embodiments provide a system that facilitates the use of an electronic device. The electronic device may be a keyboard, a mouse, a trackpad, a remote control, a mobile phone, a wireless phone, a toy, a portable media player, a game controller, and/or a camera. During operation, the system monitors a state-of-charge of a battery used to power the electronic device. Next, the system calculates a charge threshold associated with a low-battery warning for the battery based on the monitored state-of-charge. If the state-of-charge of the battery reaches the charge threshold, the system generates the low-battery warning.

Abstract: Utilizing remote control profile information for configuration of a remote control device. A media processing device may store a remote control profile, locally or on a server accessible via a wide area network, which may include information for configuring a remote control device to utilize one or more wireless remote control commands for controlling the media processing device. The media processing device may also detect one or more wireless remote control commands for controlling one or more other electronic devices and update the remote control profile to include information for configuring a remote control device to utilize those commands. It may be determined to configure a remote control device according to the remote control profile based at least in part on proximity of the remote control device to the media processing device. The remote control device may then be configured according to the remote control profile.

Abstract: The present invention can include three-dimensional remote control systems that can detect an absolute location to which a remote control is pointing in first and second orthogonal axes and an absolute position of the remote control in a third orthogonal axis. Remote control systems of the present invention can employ absolute position detection with relative position detection. Absolute position detection can indicate an initial absolute position of the remote control and relative position detection can indicate changes in the position of the remote control. By combining absolute and relative position detection, remote control systems of the present invention can track remote controls more precisely than systems that only employ absolute position detection. The present invention also can include methods and apparatus for zooming in and out of an image shown on a display based on the absolute position of the remote control in the third axis.
