PEDESTRIAN GUIDANCE DRONE WITH HAPTIC WRIST BAND INTERFACE

Figure 1

Navigation on foot in busy urban and suburban environments can be challenging, especially if the area is unfamiliar or particularly crowded. Using phone navigation and looking at a screen takes the user's attention away from their surrounds and this distraction becomes a potential hazard.

Those with blindness or loss of vision rely on walking canes, guide dogs and accompaniment to negotiate these environments and avoid hazards such as intersections, kerbs and obstacles. Audio guidance for example by headphones connected to a phone may also create a distraction, and prevent the user from fully using their hearing for hazard detection.

A pedestrian guidance system is proposed consisting of a semi-autonomous flying drone (1), a pair of haptic (vibrating) wrist bands (2 & 3) and the user's smart phone (4). The guidance drone is equipped with sensors (5) to survey its own position, that of the user, and the surrounds. These sensors include inertial, global positioning, sonar and cameras, which can, for example, detect kerbs, holes and vehicles. The drone communicates wirelessly with the user's smartphone to access map, traffic, environmental and terrain data from the internet.

The user programs a desired walking route using their smartphone, either by typing or voice recognition, and launches the drone. The drone flies semi-autonomously, ensuring a view of the user and the terrain ahead. The drone co...
