Cane Simulation(also: Virtual Cane, White Cane Simulation)

A virtual reality application that simulates the experience of using a white cane (long cane) for navigation, allowing blind users to explore virtual environments through haptic feedback. In a cane simulation, the user's finger or hand position is mapped to a virtual cane that…

Cane Technique(also: White Cane Technique, Long Cane Technique)

The set of physical methods a blind or low-vision person uses to manipulate a long white cane while traveling. Common techniques include the two-point touch (side-to-side sweeping, touching ground at each step), constant-contact (sliding the cane tip along the ground in an arc),…

Clock Face Method(also: Clock Position Method, Clock Face Orientation, Clock Method)

A technique for describing the spatial position of objects relative to a person by using the positions on an analog clock face. For example, an item directly in front of a person is at 12 o'clock, to the right is at 3 o'clock, directly behind is at 6 o'clock, and to the left is…

Clock Position(also: Clock face position, Clock orientation)

A method of conveying direction to a person who is blind by mapping the 12-hour clock face onto the user's immediate surroundings, where 12 o'clock is directly ahead, 3 o'clock is to the right, 6 o'clock is behind, and 9 o'clock is to the left. Clock-position directions (e.g.,…

Clock Technique(also: Clock Method, Clock Face Direction System)

An orientation method used in mobility training for blind and visually impaired people in which directions are communicated using the positions on an analogue clock face. The user imagines standing at the centre of a clock with 12 o'clock directly ahead, 3 o'clock to the right,…

Constructive Exploration

Constructive exploration is an interactive learning method in which a user is guided by a computer system to physically build a representation of spatial information using building blocks or other tangible objects, rather than passively receiving descriptions or studying…
