| description | Top end assistive technology devices for the visually impaired, are sophisticated electronic devices that are either hand-held, attached to a Long Cane or worn by the visually impaired user, to warn of obstacles ahead. Rangefinder ultrasonic pulse-echo techniques have readily been applied to many of these devices. On the other hand, infrared light transceivers or laser technology is also exploited to locate and warn of obstacles. Applying a rangefinder to a complex user requirement presents many difficulties. The most significant challenges are related to the interface display that conveys navigation/obstacle warning information to the user. From a cognitive perspective, other fundamental sensory channels should not be compromised in any way. This is not always the case with commercially available systems. It could be said of many, that the all important and demanding user interface design has been neglected or forgotten. |
