Ch. 7 Pros and Cons

1)   Elements of the Human/Technology Interface

There are three elements that make this successful. Control Interface is what operates the device. It can either be discrete or contininous. Selection set is characterized by size and modality. It can be represented by symbols that are used to represent ideas, computer icons, lines drawings or pictures.   

2)   Characteristics of Control Interfaces

The placement and size of the control interface, how it is activated and what the feedback is. There are so many positive things about the characteristics; it helps with movement which can generate a force, external to the body. It helps with the muscles.

3)   Selecting Control Interfaces for the User

It interfaces with either direct selection or indirect selection. This is suitable to help assist individuals with gross motor control.

4)   Control Interfaces for Direct Selection

Control Interfaces typically have greater numbers of targets and require more refined resolution skills.

5)   Control Interfaces for Indirect Selection

Control Interfaces have eight or fewer targets and are more suitable to assist individuals with their gross motor skills.

6)   Internet Use By Persons with Physical Disabilities

Persons who have physical disabilities only require access to a computer. A negative insight would be regarding to Internet access is that it could reduce interpersonal contact and isolate people with disabilities from social interaction.

7)   Other Considerations in Control Interface Selection

Long standing rehab is a positive thing for individuals with disabilities. It assists with speed, accuracy, ease, use and performance. In some case the individual can only have only one body site.

8)   Development of Motor Skills for Use of Control Interfaces

The individual can broaden his or her repertoire of motor capabilities and the number and type of inputs that can be assessed and the individual who lacks the motor skill to use interface functionally can develop these skills. Having access to a device to participate in a motor training program.

9)   Output Component of the Human Technology Interface

This part is dealing with speech which is the most important part of the body. Digital recording stores human speech in electronic memory circuits so that it can retrieved later.. Speech synthesis generates speech electronically instead of storing the entire signal. Text to speech programs convert text characters into codes that is translated into speech.
