Recently there has been demand for display equipment capable of advanced expressions in spatial design. For example, there is the Adobe Interactive Wall at Union Square (New York City, 2007), and the Zero Energy Media Wall of greenPIX (Beijing, 2008) using LEDs placed on the whole facade. The simple display of information contents is becoming insufficient,(More)
We propose the concept of shape memory alloy motion display (SMD), a new type of physical display, and introduce a plant-shaped robot "Himawari" based on this technology. SMD is a display apparatus taking advantage of existence of an actual object, and gives visual expressions by movement and change in shape of actuators, which are components of this(More)
The goal of this project is to use shape-memory-alloy actuators to realize a wriggling creature. Normally, a shape-memory-alloy actuator generates a well-defined action (robot appendages grip something or walk). But in this project, precisely controlled actuators express wriggling and creature expression. It demonstrates that an assembly of actuators can be(More)
The Luminescent Tentacles system is a scalable kinetic surface system for kinetic art, ambient display, and animatronics. The 256 shape-memory alloy actuators react to hand movement by fluid dynamics and Kinect. These actuators behave like waving tentacles of sea anemones under the sea, and the top of the actuator softly glows like a bioluminescent(More)
