[MUSIC] Assistive technology eliminates barriers and enhances opportunities in education, rehabilitation, employment, transportation, independent living, and recreation. And help people with disabilities function independently. Students with disabilities use assistive technology in order to perform functions that might otherwise be difficult or impossible. Assistive technologies can include mobility devices, such as walkers and wheelchairs. As well as hardware, software, and peripherals that assist students with disabilities access to computers and other devices. Assistive technology can be low-tech and inexpensive, like a pencil grip, or high-tech and more sophisticated like a computer. Please see the list of assistive technology definitions in this module for descriptions of the most common devices. It is helpful to understand the assistive technologies used by students because it helps you appreciate the need for accommodations. Wheelchairs are one of the most common assistive technologies. Maybe you have notice public buildings with many steps, leading up to the entrance with old heavy doors. What would do if you were teaching in a building that was not accessible to a student in a wheelchair? At most institutions you could contact the university registrar or your department chair to be assigned to an accessible classroom. Another common device is the teletypewriter, or TTY. Have you ever received a phone call from a deaf student? Consider Prima, a student who is hard of hearing and wants to place a phone call to her instructor. She has hearing aids and a traditional phone, which is not compatible with her hearing loss. How does she make a phone call? Someone with limited hearing can use the Telecommunication Relay System, or TRS, to place a call. When a person with a hearing or speech impairment initiates a TRS call, the person uses a teletypewriter, TTY, or other text input device to call the TRS Relay Center. And gives a third party the number of the party that he or she wants to call. The third party places an outbound traditional voice call to that person, then serves as a link for the call relaying the text of the initiating party in voice to the called party. And converting to text what the called party voices back to the calling party
