June 2015 Anna Fransson Abstract This thesis objective was to design a workplace integrated system for people with visual impairment for LVI Low Vison International The system is in the same category of video magnifiers as the company s other products and it was desired from the company that the product maintained the overall LVI design language Initially a pre study was performed that consisted of identifying the user analyzing the market and learning more about the product family and the design Some industry related knowledge such as knowledge about lenses and cameras was studied to facilitate the continued work With the perceived information product specifications was established Next the different concepts was generated and evaluated in an iterative process The parts was individually evaluated but also assessed to fit together as modularity is of great importance for the company As some parts in the system are re used from the existing system there were continuously prototypes built to test the newly designed parts These concepts resulted in one fully functional system with superior picture quality The system is designed to be a part of the product family at LVI and to match the previously set product specifications The result is presented as a fully functional and look and feel prototype along with rendered pictures Keywords Assistive products visual impairment picture quality product development design
