Research on devices for visually (partial or total blindness)

First of all for total blindness a braille keyboard could be used, this unlike a standard keyboard has bumps on the keys written in braille for each letter, this way someone  blind could feel the keyboard and feel which keys are which enabling them to write. This was created by Louis Braille in 1824.

 Software for someone completely blind could include siri or cortana, siri is made my apple and cortana Microsoft and they enable a hands free and vision free way of navigating a phone. For example if you say search CSGO memes it will search for it and then display it auditory for you to see.

For someone partially blind a magnifier on screen can be used, this is software to enhance certain areas on the screen for help in things such as reading small writing. This enables someone to see it enlarged.

Hardware for this would include augmented reality glasses, these can help the partially blind to see by creating a false replica of the reality around them. This enables them to see where they are going and what is happening and a big creator of this is google.

Research on devices for motor impaired

One device used for motor impairment would be a puff and suck switch. For people who do not have the ability to move and control things or even talk it enables them to via their breath. For example Steven Hawking who blows into a switch to select a letter or sucks to move to the next letter a long. This then is displayed through speakers to help him talk.

A piece of software that can help in motor impairment works through moving your eyes. There is a monitor that can read eye movements and when your eyes hover over a letter or word it tracks that movement and then selects that letter or word. These are called augmentative and alternate communication screens.

Research for those auditory impaired

An example of a device used for those with auditory impairment is ALDs, these amplify sounds so that people who are partially deaf can hear things as they are made much louder. This enables them to hear speech.

Another example would be alert devices, such as devices that flash or vibrate when a doorbell goes off or an alarm, when it vibrates of flashes it means they can still be alerted via the device and know someone is at the door or that they have to be up at a certain time.
