Reusing a light source to reflect a Heads Up Display (HUD).

Getting information from personal electronic devices (GPS, phones, etc.), instrument panels or dashboards while in motion can be a challenging and dangerous because the line of sight is temporarily broken.

Many of the existing alternatives require the user to look away from the motion path, are not mobile or (in the case of voice activated systems) do not provide a visual cue.

This invention provides a hands-free visual cue in line with the user's motion path by reusing its mobile personal electronic device screen's light source to project relevant information (See Figure 1). The user in turn avoids looking-away from the motion path, while maintaining relevant information in the line of sight.

The mobile personal electronic device will contain the necessary software and sensors to detect its position relevant to the reflective surface (e.g. windshield, visor). By reusing the light source of the electronic device's screen the user gains a projection area that could act as a HUD and thus eliminating the need for a standalone HUD. Furthermore, the software will format the screen image to present the image correctly onto the reflective surface. Since the screen's light source will be re-used to project the reflected image, the device can be placed in the more advantageous position to the user.

A device that has cellular connection and a combination of sensors (e.g. accelerometer, GPS, compass) can provide t...
