Enabling nonexpert construction of basic sensor-based systems
Susan Lysecky, Frank Vahid · ACM Transactions on Computer-Human Interaction · 2009
Technology trends have enabled deployment of low-cost sensor-based systems, but designing customized sensor-based systems to carry out specific tasks still requires costly engineering by experts. We briefly summarize eBlocks, a technology enabling nonexperts to quickly construct basic customized sensor-based systems, without requiring electronics or knowledge of programming languages. We describe experiments illustrating successful construction of Boolean sensor-based systems by novice users, focusing on intuitive logic and state block design. Additionally, we present preliminary experiments demonstrating usability of integer-based blocks and introduce a programmable block and the corresponding configuration methodology intended for nonexpert users.
