Utilization of mixed reality tools in the design of wireless assistive products

The focus of this paper is on the use of mixed reality tools, specifically augmented reality (AR) andtangible augmented reality (TAR), for evaluating design concepts and soliciting feedback in the design of assistive products. AR and TAR are tools that allow a person to look at an environment where computer-generated elements are dynamically shown alongside real objects. In the context of product development, it allows a 3D model of a product (such as an appliance on a countertop) to be viewed within a real environment. Additionally, it can allow a user to a user to move, operate and interact with the virtual product. Technologies such as AR and TAR have become more accessible to regular users as computing power has become smaller and more powerful. While use by consumers is still somewhat limited, AR is already finding uses in design. This paper will present the current challenges that must be addressed related to using AR including implementation and use of AR by designers, the level of validity in representing a product to users with disabilities, and ability of users to use the technology to provide useful/accurate feedback on a concept compared to manufactured physical prototypes.
