Abstract

With the rapid advancement and broad applications of intelligent vehicles, the design towards the on-board intelligent system has emerged as one of research hot spots in the area of automotive software. In addition, graphical HMI (Human-Machine Interaction) has become the most important means of human-machine interaction thanks to its good user experience. For better graphical human-machine interaction, the framebuffer scheme provides a virtual driver scheme for display devices, which not only improves the portability of graphics system but significantly facilitates the development of graphical applications. Based on the framebuffer technique, this work proposes a graphical HMI mechanism for intelligent in-vehicle system, and then a lightweight GUI (Graphical User Interface) system based on our Hive operating system, which is called HiveGUI, is implemented upon embedded ARM platforms. The extensive measurement results show that the framebuffer-based HiveGUI system usually consumes very few memory resources (i.e., less than 50M) and low CPU occupancy (i.e., less than 8%) in our self-developed intelligent in-vehicle system, and thus can offer good experience for automobile users.
