Generally, this disclosure provides systems, devices, methods and computer readable media for accident avoidance during mobile device usage. The mobile device may include a processor, a camera, one or more sensors, and accident avoidance circuitry. The accident avoidance circuitry may include user focus detection circuitry configured to detect that an application executing on the processor requires attention focus of a user of the mobile device; motion detection circuitry configured to determine motion of the mobile device based on input from the camera or from the one or more sensors; obstacle detection circuitry configured to detect obstacles in the path of the determined motion of the mobile device based on input from the camera; and warning generation circuitry configured to generate an alarm to the user based on the detected user attention focus, the determined motion and the detected obstacles.
