There already are several technological aids for the visually impaired for detecting obstacles and for navigation. These aids are however not geared to one another and  make a strong appeal to the perceptual and cognitive skills of the user. With maintaining the advantages of the classic white stick (recognition, passing on physical signals), there obviously is a strong need for an integrated solution that will add the possibilities of modern technologies to this classic cane. 

The I-Cane system will be equiped with several modules. Each module will have various functions of which the user can choose by means of the so called ‘plug and play’ options.  Choosing functions based on the user’s own requirements is an enormous step forward. Integration and configuration are key words in this perspective.

The concept is based on a modular and integrated construction for the following functions:

1. obstacle detection: to prevent the users from barging into obstacles on their way;
2. navigation: to find the way via a predetermined route;
3. integration of communication from external sources such as local information and change of schedules;
4. information provision by means of the handle (Tactile Arrow);
5. central intelligence to watch over security.
