Spin and roll: convex solids of revolution as playful interface
We present an interactive system that uses convex solids of revolution as playful interface manipulated on tabletop display. Interaction is based on the unique movements of the solids such as rolls and spins in addition to usual pointing and dragging. Touching of the solids on the display is detected by a sensor-sheet and used for applications. We developed some contents such as a draw tool and gaming applications that make full use of the solids.
Stick and roll: a physical interactive system using curved displays and rolling batons
We present a physical interactive system in which a player manipulates batons as interface on curved displays. Touching of batons on the displays are detected by sensor-sheets based on electro-magnetic induction. To show the feasibility and effectiveness of the system, we developed digital picture book contents in which a player uses batons in various ways such as rolling, pointing, and sweeping to interact with the sceneries.
The incidence of dead and dying fish in the Moray Firth, September 1963
Dead and dying fish were reported from the Moray Firth during a period of 15 days in September 1963. The initial mortalities were in the inner Firth, but they later spread outwards, especially eastwards along the southern shores of the Firth. Mass mortalities of the lugworm (Arenicola marina) also occurred in Scottish waters in 1962 and 1963, and at Balintorein Easter Ross fish and lugworm mortalities were contemporary.
