New technologies in arm/hand prostheses allow greater functional use, user comfort and natural looking appearances than in the past. Batteries, microcomputers, circuitry, lightweight materials and other advances have improved the life of people who have arm/hand amputations. Older technology relied on “hook” and other limited terminals. Today arm prosthetics include grippers/holders of tools and implements including carpentry and mechanic tools and aids for daily living such as eating utensils, cutlery and outdoor recreation devices. Durable, natural looking hand covers provide an attractive appearance, as well as, improved functionality.
82. Array Microphones
Array microphones are designed to capture the voices of multiple speakers and may be useful for conferencing, recording meetings, and connecting to assistive listening devices. They are typically used in conference room/small group settings.
83. Articulating Keyboard Trays
Articulating keyboard trays allow an individual to position the keyboard at variable heights and angles. Some trays go from sitting to standing positions and are equipped with enough space to handle a mouse; other systems offer a separate mouse tray.
84. ASR/ Voice Shadowing / Voicewriting
Automatic Speech Recognition (ASR) is a technique in which a person, often a transcriptionist, combines the use of speech recognition software with verbatim repetition or "shadowing" of what is being said by another person.
The ASR technique is sometimes used in a courtroom setting by a court stenographer, who would speak into a "steno mask" to isolate the person's voice from background noise. The technique might be helpful in a meeting setting for some individuals who are deaf or hard to hearing, by providing a verbatim transcript as the meeting is taking place. The technique is sometimes called voice shadowing or voice writing.
85. Assist Lift Cushions
Assist lift cushions assist people with getting up from a seated position.
86. Assistive Listening Devices (personal)
Personal assistive listeners reduce problems associated with background noise in one-on-one listening situations. By sending the sound signal directly to the individual's ears (using a headset, ear bud, hearing aid, etc.), an ALD enables an individual to hear and understand important sounds. Personal assistive listeners provide amplification and sound clarity.
87. Assistive Listening Devices and Sound Field System
Assistive listening systems, also known as assistive listening devices (ALD), transmit sound directly to an individual who is wearing a sound receiver (hearing aid, headphone, neck loop etc.). ALDs reduce problems associated with background noise in one-on-one and group communication. By sending the sound signal directly to the individual's ears, an ALD enables the individual to hear and understand important sounds while also reducing frustration associated with hearing unwanted background noises.
There are three major types of ALD technology: FM radio signal, infrared light, and induction loop systems. FM systems transmit sound via radio waves. FM broadcast frequencies (72-76 MHz) are designated for use by FM systems. Infrared systems use lightwaves to send electrical signals to receivers that convert the electrical signals back to electrical energy and then sound. Induction loops use electromagnetic transmission to send sound through a loop of wire surrounding a seating area. A personal amplified system is another ALD option for one-on-one conversations and home media purposes. The personal systems are very small and portable and involve the use of a small microphone and receiver.
ALDs can be used to accommodate applicants or employees who are hard of hearing and who benefit from amplification. ALDs can be used for one-on-one communication with coworkers or clients, small group meetings and training situations, or large-area listening situations, such as conferences or social events.
88. Assistive Technology Consulting
Consultants providing information on integrating assistive technologies into existing systems, including working with IT infrastructure security features.
89. Audio Descriptive Services
Captions for deaf and hard of hearing individuals across multiple media platforms including TV, internet and cinema.
90. Augmentative and Alternative Communication (AAC) Device
Communication aids provide communication access to people who have speech, hearing, or cognitive impairments. By typing words and sentences or touching pictures and symbols, an individual who has no speech or limited ability to speak can communicate through text, synthesized speech, or a prerecorded voice. Communication devices can be used to communicate in situations involving personal communication, groups, or the telephone.
