Abstract

According to the invention there is provided an object detection device for use by a visually impaired individual comprising a time of flight camera and an associated tactile feedback unit, whereby, the time of flight camera receives an image within a viewing range of the time of flight camera; the object detection device produces object detection information regarding: a presence of one or more objects detected in the image, an approximate size for each detected object, and, an approximate distance to each detected object; at least a portion of the object detection information is transmitted from the time of flight camera to the tactile feedback unit; and, the tactile feedback unit relays the transmitted object detection information to the visually impaired individual. The advantage is that a visually impaired individual will be provided with more object detection information then with any other known device. In particular, the time of flight camera allows distance information to be provided to the visually impaired individual, thus allowing the visually impaired individual to build a realistic three-dimensional representation of the surrounding environment. This greatly increases the visually impaired individual's ability to safely negotiate any obstacles and/or objects in the surrounding environment. Moreover, the visually impaired individual can interact in a more full and immersive manner then was previously possible with all other known types of prior art devices.
