For most users the Graphical User Interface (GUI) is the application. The appearance, style and usability of the GUI may all affect the popularity and success of an application, so GUI development is a vital part of any project. Successful GUIs are developed in close co-operation with users with frequent usability testing and review.

GUIs for new technologies

The richly functional GUI, typical of a Windows application, is familiar and has been with us for many years now. But as more and more applications move to the web-browser and, further, onto hand-held devices there are new challenges for GUI designers. Some parts of the typical rich Windows GUI simply do not translate onto these new platforms so requiring some radically different approaches to interface design.

A new look for an old system

Developing a new application with a productive GUI is one thing but there are still many non-GUI legacy applications in regular use. This old software is tried and tested, and often vitally important to the business, and so has to be maintained. These old applications can be given a new lease of life by adding a GUI as a separate layer, thus bringing the application to a new platform or audience whilst leaving the proven underlying system intact.

Tessella has experience of developing GUIs across a broad range of technologies and customer business domains, from desktop PCs to hand-held devices and touch-screens, from X-Windows to Microsoft Windows and Windows CE.
