Alternative multi-user interaction screen: initial ergonomic test results

Author: Smith, Andrew C Date: May 2010 The authors investigate a potentially low-cost multi-user computer pointing interface. Given a choice of four targets arranged on the screen, the authors looked at what the user’s preference is in visiting the targets with a hand-held light ... Read more
An architecture to negotiate and monitor energy exchanges in the smart microgrid

Author: Smith, Andrew C Date: Aug 2022 Traditional electrical power sources and their long distribution networks can no longer cope with the ever-increasing need for energy. Distributed energy generation in close geographical proximity to the consumption point is an alternative ... Read more
The building is the program

Author: Smith, Andrew C ; Gelderblom, H Date: Sep 2013 We present interaction with a physical building as a hypothetical example of peripheral interaction. The state of the building's windows provides input to an algorithm which produces abstract art as the result of the interaction. This paper ... Read more
Cluster-based tangible programming

Author: Smith, Andrew C Date: May 2014 Clustering is the act of grouping items that belong together. In this paper we explore clustering as a means to construct tangible program logic, and specifically as a means to use multiple tangible objects collectively as a single tangible ... Read more
A design approach to adapting maker community projects to the IoT constrained device philosophy
