“IBM” logo or “Fraps” logo. • Gestalt also uses shapes and colors to infer images which are not there.

“Multistability”.

• Gestalt also uses shapes and colors to infer images which are not there. In order for this to work the user must believe what they are seeing as well, the user will be tricked by the images. Gestalt usely will use three diffent images such as two could be the same, background and main images or colors can be almost any colors but Gestalt manly uses dull-colors. This is known as “Multistability”.

Reification

• Gestalt uses lines and shapes to produce 3d like images. This makes the user belive that they are seeing 3d images on 2d page. Gestalt uses lines and shapes to produce the image and by tilting axis the user think becouse the brain is being tricked by the drawing

Behaviour models

• Behaviour models are based apon the client they are many Behaviour models, some of the most poplar are

Specialized interface

• Braille keyboards• Speech recognition• Screen-Readers • Sign Language-appreciations

Braille keyboards

• Braille keyboards allow blind people to use computers when typing, also braille keyboards use dots instead of using letters but the dots infer a letter such a four dots is “F”. The user will “feel the dots” then the user will proceed from there.

Speech recognition

• Speech-recognition can be used in-almost any situation or clients needs such as if the user was blind this allows the user to also impute they demands and commands, via speaking to the computer system. The user will say quote ‘start, all-programs, Microsoft-office, open Microsoft word’ end quote, the software will open it then the user will relay the needed text and so-on.

• This software is very effective at-this-time aslong as it is an third-party-appreciations like dragon and others. However some O.S. have in installed like Microsoft windows vista, Microsoft windows 7 and MAC there speech-recognition software is not as advanve as others on the market but it is pre-installed.

Screen-readers

• Screen-readers allows the use of the computers A.I. the screen-reader will relay the text on-screen, if the use was to have quote ‘hello world’ end-qoute the screen-reader will read that quote to the client. Then the client can determine what they will do.

• Screen readers comes installed with many O.S. from windows it called ‘speech’, or ‘voice reader’ depending on what windows O.S. you have installed also MAC has it own copy. However theses may not be the best screen-readers around

Sign Language-appreciations

• Sign Language appreciation allows the deaf user to see what the person or sound is saying by using ‘Sign Language’ the appreciation works very well but has some-issues with a number of O.S. but the appreciation works the same way like when you speak-to-a-real person.
