Previously, there has been extensive research regarding the measurement of movement within the context of sports skills. In this research, we focused on football – one of the most famous sports in the world. Specifically, we focused on football juggling: one of the most practical exercises for novice footballers to obtain fundamental skills such as kicking, passing, dribbling and trapping. The aim of this study is to utilize a smartphone’s accelerometer as a sensor to measure football juggling skills. Unique points of this study included the use of machine leaning and frequency analysis. To score the football juggling skills of a user, we developed a prediction model to measure their skills, as well as a smartphone application.
By incorporating digital technology in spaces, this research aims to explore new possibilities beyond conventional spatial design. By unifying the technology as module mechanisms, we believe digital technology can more easily be applied to spatial design. In this study, we focus on interactive indirect lighting products using module mechanisms. By using these module mechanisms of ambient media, we are developing an indirect lighting system that users can freely design the shape and behavior of.
Tapcon is an energy-efficient game controller which utilizes tactile presentation techniques. By using this tactile presentation, we developed original games with improved realism. By using a motor fader with sensors and actuators, we were able to produce a light-weight controller with reduced power consumption. Additionally, we created two games where this controller can be used: a digging action game, where the intensity of vibration changes depending on the hardness of the ground; and a bow and arrow shooting game, which presents a tactile experience of actually pulling the bow and arrow.
Recently, by utilizing the 4DX system, projection mapping and interactive theater have made image expression more realistic by adding interactive aspects to video. On the other hand, there are few systems to enjoy highly realistic and interactive images at home. In this study, we propose a system – created with openframeworks and Arduino – that can improve realism and entertainment of images. This automated system can change the temperature and create vibrations accordingly to suit the characteristics of a scene.
Recently, there is growing interest in achieving better sleep quality. Therefore, this research is investigating appropriate stimuli in response to sleep depth, and suggests an interface to improve the quality of sleep. We have developed an application that reports sleep depth by using a smartphone to detect the body motion of the user during sleep. This app sends the measured data to a PC. Moreover, the app provides light and sound stimuli in line with the measured sleep depth and suggests a pillow-type device that may improve the quality of sleep.
In recent year, related to individual training of soccer, an attempt to take advantage of accelerometer etc. on researches and micoach which can tune your technique and kick like a pro with instant feedback on power, spin, strike and trajectory are increasing. The author pay attention to free kick’s simulation, the physical system of free kick’s simulation was conceived.

Today, there are many types of digital toys available for children. Actuated toys, such as remote-controlled cars, are getting more intelligent and smart: we can now control these kinds of toys with smartphone applications. On the other hand, such controllers are sometimes difficult for children to control. Thus we propose an easy way to control a motorized car by using simple sounds. Once a user rings a bell, it makes a duck toy move towards the direction of a user. Our duck toy has two capacitor condenser microphones to detect the location of a sound source. Then, through frequency analysis, it detects the pitch of a sound. As a result, a user can enjoy being like a mother duck.

Paul is currently working on a research project here at Tokyo Metropolitan University’s System Design faculty looking at how to make information on natural hazards (such as earthquakes, active volcanoes and typhoons) in Japan more accessible and usable. It’s very early stages but the plan is to build a smart phone app. We’ve recently launched a mini-site for the project at hazards.jp. This research will build on some of the findings from Paul’s PhD and the MyFireWatch project.
