Abstract: Navigation instructions using low-bandwidth signaling are supported in an alternative user interface that may be utilized as either a full replacement or as an enhancement to conventional visual/audio navigation interfaces. In one illustrative example, the alternative interface makes use of the more constrained, but generally broadly available low-bandwidth signaling capability of mobile devices to encode navigation instructions in the form of varying patterns of tactile vibrations that may be imparted from the device to a user as haptic feedback. The user can sense the vibrations and readily translate them into the navigation instructions without needing any kind of special decoding equipment or using any special techniques. The vibrations may be encoded using easy to remember patterns so that a full and rich navigation feature set may be accessed with minimal training on the user's part.

During a sound emit period where a warning signal is being outputted to an sound emitter for emitting a warning sound, the output circuit outputs a monitor voltage from an output terminal by half-wave rectifying and integrating the warning signal upon a change of a potential of the potential change terminal to a high level.

During the sound emit period, the failure determining section sets the potential of the potential change terminal to a high level and determines whether the short-circuit failure occurs based on the monitor voltage.
