POP Cart 2021


In this study, we developed POP Cart that uses a shopping cart and an agent to recommend products. The agent on POP Cart is designed to call the customer by name, chatting and making recommendations to the customer casually like a friend. POP Cart has two advantages: first, the agent can form a positive relationship with the customer is in the store, which could be beneficial for a high recommendation success rate, as found in previous studies. Second, the agent can make multiple recommendations for different products according to the position of the customer while they are shopping in a large store. To evaluate the effectiveness of the recommendations made by the POP Cart agent, we conducted a field experiment in a real supermarket in Japan, where 49 participants shopped under three cart conditions. The results revealed that having an agent on a shopping cart is an effective way to recommend and sell products.

Grov ( 研究紹介ページ ) 2017-2018


The Grov is a low-cost data glove that brings intuitive interaction to any applications. It can sense your finger bendings, abductions and touch points at the same time for the first time in the world. Based on conductive fiber sensing, the Grov is lightweight, soft, washable and hard to break. Grov supports your hand interactions at VR, gesture recognizing, motion captures and shortcut for any apps. With a focus on intuitive hand interaction, design and durability I bring the most immersive experience.

DroneHelmet 2018


DroneHelmet is the concept of automated walking; it applies the paradigm of automated driving to human movement. As the legs are moved without the user's cognitive effort, the user can focus on what they want to do while walking. Unlike conventional navigation systems which depend on the user's voluntary walking, automated walking generates the user's physical movements including start/stop of walking. A DroneHelmet prototype is built and tested to validate the concept. Ungrounded force generated by the drone helmet induces the user's postural reflex and the corresponding body movements. This is collaborative work with NTT Docomo Research Lab.

JoyKey 2017


JoyKey is a one-handed hardware keyboard with 4x3 grid slide keys, called a JoyKey. It can be used for Japanese text entry based on the flick input method. We conducted a user study to compare the accuracy and input speed of the JoyKey and a software keyboard on a touch screen under two conditions (eyes-free and non-eyes-free). Results show that the software keyboard cannot be used under the eyes-free condition because users cannot feel tactile feedback on a touch screen. In contrast, using the JoyKey, users can enter text under both the conditions with relative ease.

BaroTouch ( Movie ) 2016


We present BaroTouch, a technique that leverages a waterproof mobile device's built-in barometer to measure the touch force. When an airtight waterproof device is touched, the distorted surface changes the air pressure inside that device and thus changes the built-in barometer value. Although this change varies under different airtightness conditions, our technique can measure the touch force independent of the airtightness conditions.

MonoTouch ( Movie ) 2015


MonoTouch is a technique which can defferentiate some touch gestures using single electrode and a capacitive touch sensor. MonoTouch's electrode has a special layout which is 3D-printed, and sensor's responses are different between touch gestures (tap and some directional swipes). MonoTouch uses the number of responses and response time to differentiate touch gestures.
