LineFORM is a novel Shape Changing Interface which has the form of a “Line”. Lines have several interesting characteristics from the perspective of interaction design: abstractness of data representation; a variety of inherent interactions / affordances; and constraints as boundaries or borderlines. By utilising such aspects of lines together with the added capability of shape-shifting, we present various applications in different scenarios such as shape changing cords, mobiles, body constraints, and data manipulation to investigate the design space of line-based shape changing interfaces.

Down the ages, people have been utilizing various stationeries to draw precise figures by own hands. On the other hand, as technology developed, CAD software has enabled us to draw such figures easily on the display. In this research, we propose a compass-based drawing interface, “COMP*PASS”, which integrates advantages of digital control to manual works. By focusing on the tool compass, we developed a novel drawing interface that can draw not only circles but also other kinds of figures under physical environment. In concrete, the radius of the interface is regulated according to the rotation of the device therefore the user only needs to twist the interface to draw a specific figure. The interface is composed of a rotary encoder which detects the rotation angle, and a servomotor which regulates the radius of the drawing.
