The Parking Sensor, a spin-off from the travel aid for the blind, the Sonic Pathfinder, was first invented by Dr Tony Heyes at the University of Nottingham. England. Toyota introduced ultrasonic Back Sonar on the 1982 Toyota Corona, offering it until 1988. [7]
The Optacon (OPtical to TActile CONverter) [1] is an electromechanical device that enables blind people to read printed material that has not been transcribed into Braille.The device consists of two parts: a scanner which the user runs over the material to be read, and a finger pad which translates the words into vibrations felt on the finger tips.
The term "echolocation" was coined by zoologist Donald Griffin in 1944. But the phenomena was known about earlier, for example, Denis Diderot reported in 1749 that blind people could locate silent objects. [1] Human echolocation has been known and formally studied since at least the 1950s. [2]
A curvilinear array ultrasonic transducer for use in medical ultrasonography Inside construction of a Philips C5-2 128 element curved array ultrasound sensor. Ultrasonic transducers and ultrasonic sensors are devices that generate or sense ultrasound energy. They can be divided into three broad categories: transmitters, receivers and transceivers.
Telesensory Systems, Inc. (TSI) (later TeleSensory Corporation) was an American corporation that invented, designed, manufactured, and distributed technological aids for blind and low vision persons. TSI's products helped visually impaired people work independently [1] with computers and with ordinary printed materials.
The Trinetra project aims to develop cost-effective, independence-enhancing technologies to benefit blind people. One such system addresses accessibility concerns of blind people using public transportation systems. Using GPS receivers and staggered Infrared sensors, information is relayed to a centralized fleet management server via a cellular ...
Common applications include search and rescue, surveillance, and customer analytics (for example, people counters). Modern technologies proposed or deployed for human sensing include: [1] Acoustic sensors; Image recognition of human shapes; Infrared detectors; Pressure-sensitive floor tiles; Radar; Chemical sensors
BrainPort is a technology whereby sensory information can be sent to one's brain through an electrode array which sits atop the tongue. [1] It was initially developed by Paul Bach-y-Rita as an aid to people's sense of balance, particularly of stroke victims.
