Paper, as a traditional material for art and communication, shows great potential as a medium for organic user interfaces, with its ubiquity and flexibility. However, controlling and powering the sensors and actuators that enable interactive paper-crafts has not been fully explored. We present a method of selective inductive power transmission (SIPT) to support interactive paper-crafts. The novelty of this method is that the power transmitter can be controlled to selectively activate one specific receiver at a time through inductive power transferring with multiple receivers. This was achieved by changing the output frequency of the power transmitter to match the impedance of the receivers. The receivers could be embedded or printed to drive paper-crafts. Based on inductor–capacitor oscillating circuit and a function generator with a power amplifier, we developed two different prototypes of SIPT. By comparing the performance of both prototypes, we discussed the advantages and disadvantages of the two systems, and their applications in different contexts of paper-crafts. In addition, we proposed the instructions for using SIPT in developing interactive paper-crafts. With this technology and instructions, we hope to facilitate users to easily design new types of paper-craft systems without being concerned about the arrangement of wire connections to power supply on a massive scale.

The article focuses on Time Follower's Vision which is a mixed-reality-based visual presentation system that captures a robotic vehicle's size, position, and environment, allowing even inexperienced operators to easily control it. Researchers have developed teleoperated rescue robots for search-and-rescue missions within unknown disorderly regions such as collapsed buildings, postearthquake debris, and natural disaster sites. An egocentric view camera capturing the first-person viewpoint is typically installed in such simple remote control vehicles. By observing the camera image without an efficient human interface system, the operator tends to misinterpret the robot's position and direction, which in turn reduces the probability of achieving critical mission objectives. To appropriately attach an exocentric view camera, the vehicle needs to be larger. Such a large body often disturbs the vehicle's activity. Therefore, it's more effective to provide a virtual exocentric view. Another problem with an egocentric view camera is that it only shows an image of the environment from the vehicle's current position. However, when the vehicle advances forward, a previous image captures more environmental information on the vehicle than a current image. This image's viewpoint contains the current vehicle's position.
