Force field maps for the blind
Researchers from Greece have come up with another way to help virtually impaired people take advantage of current technology. With the use of new software and force fields, blind men can now use maps.
The concept of offering maps to the blind is not an entirely new concept. In fact, it’s been done with paper and cardboard even before the Greek research team used imaging methods. What’s distinct about the Greek research is that it can easily produce a virtual map after scanning a locale’s architectural model.
Using standard video cameras, the model is shot in a full 360-degree range. The visuals are then mapped out using points in a plane by the software and laud out. Once processed, the user can use either a CyberGrasp Wand or a Phantom Glove. Both offer feedback in terms of pressure, simulating a force field that can be “touched” by the visually impaired.
“Each point on the grid has an associated force value,” says Konstantinos Moustakas, head researcher for the virtual map project. He then explained that by applying accurate pressure fields for the points, it will be just as easy for the map’s blind user to figure his way around a city as a sighted person would.
Moustakas then revealed that the map has applications even for the sighted. In cases where people cannot browse through maps with their eyes, they can feel their way around. This can be applied to police or military combat situations. Development of the technology is still in its middle stages and may take some time before a finished product can be seen.
