This masters thesis is about how to enhance creativity and investigates the design process of interaction designers, in terms of the creative process, design support tools and especcially through a concept presented in this thesis. The concept is called DSTZ (Design Support Tool Z) and suggests ways in how to support a designer in the creative process. An empirical study was carried out in the thesis that consisted of a survey conducted on 8 "interaction designers" investigating how interaction designers work and if they require or need any design support. A design survey was later conducted on 18 "interaction designers" of which 9 were professionals and 9 were students, to investigate the concept DSTZ and the creativity enhancing aspect. The resuls from the empirical studies show that a design support tool is desired and DSTZ has features that are useful and can enhance creativity. The features consist of 8 palettes and 3 funtions that are manifested in DSTZ. Further investigation is required in order to find data that support the statement that creativity can be enhanced through a design support tool.
