Assistive Technology Access

Specialized pointers (mouse):

As many people use their pointer and question its ease of use for efficiency. However, for many users the mouse presents significant physical challenges. In addition to the traditional mouse approach that we are all used to, there are several other approaches that may be less familiar: these include rollerball, head-on, joystick and visual. The general idea of ​​the rollerball mouse is that the user does not need to keep their wrist in a fixed position, possibly exacerbating RSI symptoms or presenting a physical position for hands that are not viable. Rollerball mice come in a lot of versions but basically all offer a floating ball that can be changed with the reach of the hand, the palm of the hand, at the end of the hand or other technique. The general concept of mouse carried head is that the user moves to their head and / or something worn on the header to move the mouse on the screen; This feature is often associated with a sip controlled system that allows the user to use their air to perform by clicking; or with a system scan where allowing the mouse over the rest at a specific point in the screen a user-defined specified time executes the function by clicking. Number with mobility restrictions finding the hand position on a traditional mouse is very difficult and a number of companies have brought mice based on the joystick controller concept which is easier to manage and requires a lower level of presenting reduced mobility.

In recent years there have been a number of new approaches to pointer control, and these include the use of RETINAL movements, facial tracking and vague brain waves. Moreover, there is a wide range of mice specifically provided for people with difficult mobility disabilities including quadriplegia allow access using just the head or the mouse (Jouse for example).

Voice input technology:

Vocal Entry Technology A number of companies create voice input technologies capable of providing voice control and control and speech to text features. The Windows 10 operating system includes a speech recognition utility, use speech recognition in Windows 10 , and the most well-known voice input technology in North America is probably the Dragon NaturallySpeaking product line.

Visual challenges:

The user interface is briefly presented above and an obvious consequence of using a visualization system to interact with the computer system is that people experiencing visual problems may have increased difficulty or completely prevent access to information. Generally, people with vision challenges will be described as “reduced visual acuity” or “blindness”. A TROUBLES user generally will have some usable vision and will use some visual access for computer and documentation presented under print. Many people are described as reduced visual acuity also benefit from assistive technology that assumes that the user does not have visual access.

Software enlargers:

A software magnifier can provide different magnification factor levels as well as general display management, such as contrast sets and pointer sets. These systems are often associated with the screen reading utilities. Expand Keyboards allows you to control the software features besides using the standard keys assigned The Magnifier ZoomText Hot Keys.

Prediction of words:

Word Prediction allows the user to use suggestions on words. A Word prediction software is heuristic, which means that it learns patterns patterns as the user uses WordQ .

Chart Organizer:

Rather than trying to use a purely linguistic / textual approach to organize your ideas and create opportunities for communications, graphic organizers allow you to use a large number of supported tools to process more visually Software inspiration .
