The BuzzClip is a small and discreet wearable device for people that are blind or partially sighted to be used to prevent them from bumping into hazardous obstacles to increase independent orientation and mobility. The device uses ultrasound to detect obstacles that may lie directly in the user's path. It then notifies the user of these obstacles through intuitive vibrations, allowing the user to safely navigate around any objects that they may encounter. The BuzzClip offers essential head level obstacle detection and can be attached to many forms of clothing. It helps the user navigate around obstacles above the waist, such as through busy streets with construction signs, barriers, promotional signboards and tree branches.
The Accurate Proximity Sensor ensures that the distance to any nearby obstacles is accurately measured regardless of lighting conditions or transparency of the object by sending and receiving sound waves.
The BuzzClip features Dual Range Detection. The user can select either a 1 meter range or a 2 meter range. Users can gauge the distance to an object within the specified range through intuitive vibrations from the BuzzClip. The frequency and intensity of the vibrations increase as an obstacle gets closer to the user (or vice versa). At about arm's length (50 cm) there will be 3 quick vibrations warning the user to stop and make sure the path ahead is clear.
The Twist to Toggle Modes allows the user to toggle between the 1 meter and 2 meter modes by simply twisting the top piece of the BuzzClip. The dial switch makes it easy for the user to toggle modes while wearing the device. In addition, a tactile indent indicates the selected mode to the user: off, near, or far.
The spring loaded arm can be opened and locked through a push and pull motion. The vibrator motor is at the end of this arm is encircled in a sweat proof enclosure. This allows the intuitive vibrations to be isolated, providing a stronger response signal to the user.
