DynaVox devices assist individuals who are unable to communicate reliably with their own voices due to cognitive, language and physical impairments. … DynaVox devices, like almost all Speech generating device, use a hierarchical set of pages that contain different vocabulary for different contexts or situations.
The Tobii I-Series, a family of eye-controlled communication devices, provides individually optimized communication solutions for people with communication conditions such as Lou Gehrig’s disease (ALS), autism, Rett syndrome, cerebral palsy and muscular dystrophy. … “Tobii has given me a tool that has changed my life.
► Eye-gaze control technology allows children and adults with cerebral palsy to use movements of their eyes to operate a laptop, computer or speech-generating device. ► This technology can be used for many purposes, including playing games, accessing the internet and communicating with family and friends.
DynaVox devices assist individuals who are unable to communicate reliably with their own voices due to cognitive, language and physical impairments.
Designed to address the needs of people with physical and communication impairment, these devices offer convenient computer accessibility and efficient navigation. Eye Controlled Devices. Eye tracking and eye control is a technology that makes it possible for computers to know exactly where users are looking.
Speech-generating devices are hand-held electronic devices that play pre-recorded words or phrases when the user touches a switch or presses buttons or keys. Some devices ‘speak’ words as the words are typed on a keyboard.
The device works by using forward- and rearward-facing infrared cameras that are mounted on a screen. The cameras pick up the activity of the cornea, which allows a user to stare at a phrase or a symbol and “activate” it much like a mouse click would activate a computer screen.
Eye Gaze. The eyes play an important role in nonverbal communication and such things as looking, staring and blinking are important nonverbal behaviors. … Shifty eyes and an inability to maintain eye contact, on the other hand, is frequently seen as an indicator that someone is lying or being deceptive.
Accuracy and Precision of Gaze Tracking
Accuracy is often reported by manufacturers to be < 0.5°. However, in particular for remote eye trackers, offset from the true gaze point is often found to be larger than 1° [5, 30], even in controlled environments.
Because eye tracking technology only involves cameras and light, it is extremely safe and also easy to use.
Now, thanks to innovation in the fields of gaming and virtual reality (inspired by potential profit with two huge consumer bases), eye gaze is not only getting better, it’s getting more affordable! Priced at $150, the Tobii 4C is the first affordable eye-tracking system.
Tobii Pro’s customer base currently includes more than 3,500 companies and 2,500 academic institutions, including numerous large corporations such as Procter & Gamble, Microsoft, Denso, leading market research companies such as Ipsos and GFK, and all of the world’s 50 top-rated universities.
The company also began experimenting with eye tracking technology and in 2008 launched the EyeMax, a device that individuals could access through their eye movements.
An eye tracker lets your PC know where you are visually focused, giving you an extra input mode when it comes to gaming. It also makes the interaction feel more real. Your experience becomes richer, and your instincts extend into the game itself.
These devices use eye movement to “activate” a letter, word, or phrase on a computer screen, which can then be spoken by the computer for communication purposes. To use eye gaze devices, the person living with ALS needs to be able to use the muscles that control upper, lower, and lateral eye movement.
Speech Generating Devices (SGD) or Voice Output Communication Aids (VOCA) are portable electronic devices that allow people using them to create a message and produce speech. These methods of augmentative and alternative communication (AAC) are used as a communication system for people with little or no speech.
A switch is an assistive technology device that replaces the need to use a computer keyboard or a mouse. It may allow users to control a computer, power wheelchair, video game console, tablet, smartphone, toy, and a variety of other electronic devices.
