Abstract: A motion driven event alert system and method synchronize output of follow-up event alerts on a mobile electronic device to changes in the state of motion of the device. Generally, the device outputs an initial alert in response to receipt of a new event from a wireless network. If a user fails to take action on the device after the device outputs the initial alert, the device determines a state of motion of the device and monitors for a change in the state of motion. When a change is detected, the device outputs a follow-up alert. If the user fails to take action on the device after the device outputs the follow-up alert, the device repeats the steps of motion state determination, motion state change monitoring, motion state change detection and output of another follow-up alert.

Abstract: Systems and methods for enhancing display of textual information in a video stream displayed on a portable device. In one aspect textual information is identified in frames of a video stream and is enhanced to improve visual readability of the textual information. The textual information may be enhanced by enlarging portions of frames of the video stream that include the textual information to overlay other portions of the display screen. The textual information may also be enhanced by converting the textual information in the frames of the video stream into character glyphs for display on the display screen of the portable device. Identification and enhancement of the textual information may be performed within the portable device or within systems external to the portable device and may be performed by automated procedures or responsive to user input on the portable device.
