Pilar B.'s insight:

The Tacit project is intended to help the blind navigate. It uses a pair of ultrasonic rangefinders to sense the distance to objects and converts that to pressure on the wrist conveying direction and distance to obstacles. It’s mounted to the back of the hand in order to provide maximum flexibility while staying out of the way during most activities.

Pilar B.'s insight:

Within the context of comparative perceptual studies in both real and virtual world experiments, the project aims to address three broad questions:


Could the role movement (chiefly head movement) plays in auditory perception inform factors such as spatial resolution when designing virtual auditory systems?


How can movements be translated into such a system, either as an aspect of the control interface or as a facet of the audio rendering itself?


Do differences in perception exist between sighted and visually impaired individuals?

VJTI students develop navigation device for visually impaired - Indian Express

Four final year B.
Pilar B.'s insight:

"The device consists of cameras mounted on spectacles that will send feeds of the terrain to the handheld computing device. It will convert the video files into stereo signals that will be sent to vibrators attached to the body of the blind person. The vibrations will warn users about obstacles in front of them, thus allowing them to navigate (walk) without colliding with the obstacle."

A SONAR SYSTEM FOR THE BLIND

Pilar B.'s insight:

Researchers at Boston University have developed a prototype device that can enhance auditory cues while navigating an environment. The device repeatedly emits an inaudible (to humans) ultrasonic click several times per second, and each click reflects off any objects in the environment. The reflections are then detected by special head-mounted microphones, and computer processing converts the ultrasonic signals into audible signals, which the user then can hear over custom open-ear earphones.

The end result is an "auditory image" in which objects in the environment seem to emit "sounds" to the user, with objects of different shapes and textures emitting subtly different sounds, such that the user can distinguish between them. According to BU researcher Cameron Morland (cjmorlan@bu.edu), the unique acoustic characteristics of the reflections enable the user to better distinguish the location and size "surface" properties of objects. For instance, sounds emitted by an object to the left will arrive at the left ear a bit sooner and louder (interaural time difference and interaural level difference).

Furthermore, sweeping the device over a surface while remaining the same distance from it, will produce a reflection with unchanged velocity of the surface of an object is flat. If the surface is tilted so it moves closer to the user, it will sound higher in pitch; tilted the other way, it will sound lower in pitch (a Doppler shift). A roughly textured surface will have some regions that are closer, and others that are further away, and users can easily learn to recognize those differences, and discern the resulting pattern of increased and decreased pitch. "Venetian blinds sound quite different than a flat surface, or a bookshelf packed with different-sized books," says Morland.

The BU team has built a prototype capable of simple detection of objects and open spaces, and preliminary tests show that most people can echolocate a little using the device, and improve quickly with practice. They are now refining their prototype to function in more complex, real-world environments. Morland believes that given enough practice, people should be able to echolocate very well using the device - perhaps better than they could unassisted, since higher frequencies outside the normal range of human hearing are more useful for echolocation. (Movies of the device can be found at http://cns.bu.edu/~cjmorlan/research)

Currently available Electronic Travel Aids

Pilar B.'s insight:

An Electronic Travel Aid (ETA) is a form of assistive technology having the purpose of enhancing mobility for the blind pedestrian. Perhaps the most widely known device is the LaserCane, which is a regular long cane with a built-in laser ranging system. The Mowat Sensor is an example of a pocket-sized device containing an ultrasonic air sonar system. When it detects an obstacle, the device vibrates, thereby signaling the user. The research problem of designing a better ETA is a tough one. Despite 50 years of effort, no one has been able to design an electronic device that can replace the long cane.
