An example of design improvement is shown below. It is a picture of six mobile phones, however it is an indication of how cellphones have been developed over time. We can get a glimpse of the ideas of designers, and their use to help create the evolution of mobile phones. As you can see, the first mobile had a much larger body in comparison to the later ones, and had no colour screen, however this was when the mobile phone was a new idea of development itself, as it was an enhancement from the telephone for the use of texting, and portability. Todays phones are much different, as they now have the qualities of video clip making, photographing and access to the internet along with the touch screen monitor.
The cell-phone is a important piece of technology in everyday life nowadays, thanks to the enhancements made to these products over the years. The phone is a classic example of improvement for design, and brings out many reasons why this kind of improvement is necessary.
