Interaction Group


Our group aims to realize "Human-Computer integration" which is easier to use and more cognizant by interaction design. In particular, we are researching how a computer system that is advanced and intelligent, such as automatic driving technology, sensing technology, machine learning etc., can be integrated with people.

This group considers how to contribute to the further evolution of humankind by integrating the technology evolved by humankind with humanity.

どんなに素晴らしい技術も人が使いやすくなくては意味がありません. 特に自動運転など,新しい技術,人の能力を超える技術をどのように人と結びつけるのか,様々な側面から研究を行っています.

In this paper we propose an interactive system that allows only the owner of a target object to secretly find it among other similar or identical objects, which we call SecretSign. Finding a personal object, e.g. an assigned vehicle in a car-sharing parking lot, where there are many cars that look the same or are similar, can be difficult. In addition, we may not want to notify other people which object we are looking for, e.g. a car thief waiting to steal a car when the driver opens the door. Our proposed system allows a user to find an object without notifying others of the target, using a light attached to the target object which turns on and off in conjunction with user's operation of a remote control device, while lights on the other objects turn on and off randomly.

Improving target selection accuracy for vehicle touch screens

When operating the touch screen in a car, the touch point can shift due to the vibration, resulting in selection errors. Using larger target is a possible solution, but this significantly limits the amount of content that can be displayed on the touch screen. Therefore, we propose a method for in-vehicle touch screen target selection that can be used with a variety of sensors to increase selection accuracy.

Effects on User Perception of a 'Modified' Speed Experience Through In-Vehicle Virtual Reality

In order to make the experience of traveling in automated vehicles more enjoyable, Virtual Reality (VR) experiences based on the real-world journey have been proposed. Presenting users with VR content synched to the car's actual movement decreases the motion sickness, but it also sharply limits the possible range of VR content. In this paper, we investigate whether the user's subjective perception of speed can be 'modified' by presenting VR content at a different speed than the actual speed of the vehicle, and whether users feel this experience is strange. Study participants viewed VR content occurring at a faster or slower speed than their actual travel speed in an electric wheelchair. Our results show that the participants were able to do this without experiencing a feeling of "strangeness". However, the participants did report higher "strangeness" scores when the speed in the VR content was slower than their actual speed.
