Figure 1. Dynablock is a rapid and reconstructable shape formation system, comprised of a large number of small physical elements. A) Dynablock's shape consists of 9 mm blocks which can be connected with omni-directional magnets. B-D) Dynablock leverages the 24 x 16 pin-based shape display as a parallel assembler of blocks, Dynablock is able to construct three-dimensional shapes in seconds. E) The example shows the output of a miniature model of table and a chair. The constructed shape is graspable and reconstructable.
Figure 1: FoldTronics creates 3D objects with integrated electronics. Our design software allows users to: (a) Convert a 3D model into a honeycomb structure & place electronic components into it. (b) Export the 2D layers (honeycomb pattern, wiring, insulation). (c) Fabricate the layers on a cutting plotter using sheets of plastic, copper, and regular tape. (d) After soldering and folding, the object is ready to be used: (e, f) This smart watch has a 2D display when collapsed and a 3D volumetric display (3 layers, 6 LEDs each) when expanded -the LEDs and wiring are integrated inside the object.
This paper presents dePENd, a novel interactive system that assists in sketching using regular pens and paper. Our system utilizes the ferromagnetic feature of the metal tip of a regular ballpoint pen. The computer controlling the X and Y positions of the magnet under the surface of the table provides entirely new drawing experiences. By controlling the movements of a pen and presenting haptic guides, the system allows a user to easily draw diagrams and pictures consisting of lines and circles, which are difficult to create by free-hand drawing. Moreover, the system also allows users to freely edit and arrange prescribed pictures. This is expected to reduce the resistance to drawing and promote users' creativity. In addition, we propose a communication tool using two dePENd systems that is expected to enhance the drawing skills of users. The functions of this system enable users to utilize interactive applications such as copying and redrawing drafted pictures or scaling the pictures using a digital pen.Furthermore, we implement the system and evaluate its technical features. In this paper, we describe the details of the design and implementations of the device, along with applications, technical evaluations, and future prospects.
