Chapter 33 Product Graphical User Interfaces: A Study for the Meaning and Usability on Automobile Dashboard User Interfaces in Indian Context Venkateshwarlu Varala and Pradeep Yammiyavar Abstract Product graphical user interfaces are the portals for the human–machine interaction. In our day-to-day lives, we come across several products with graphical user interfaces as the way to interact with them. These interfaces are designed to serve the several user groups across the globe. While the purpose is to communicate the meaning in the best way possible and creating a bond with their users, yet we see many interfaces irritate us at some point of time and become ambiguous to operate. There could be several reasons for such experiences. Through the product semantic studies and an experiment on different Indian user groups this paper tried to explore the meaning related issues, usability problems of automobile dashboard interfaces in the Indian scenario.

They evoke meanings in users in a way they understand, and thereby creating a successful interaction, creating a bond [1]. To design a mean- ingful interface, designers make use of different features and attributes of the product [2]. For instance in a tangible product interface, a switch to turn on/off with specific color, a handle to hold with different shape, and in case of a graphical user interfaces a set of metaphors and visual cues are used in two dimensional space.
