Maeda, Atsuhiko, Hara, Kenji, Kobayashi, Minoru and Abe, Masanobu (2011): "ClearPlate" for capturing printed information: a scanner and viewfinder in one optical unit. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 2737-2740.

As it is becoming more common for various handheld devices to be equipped with a camera, applications that use image recognition are increasing. Therefore, improving the usability of these devices by enhancing their image capture characteristics is becoming more important. We present ClearPlate -- a new optical unit for image capture. It has a physically transparent viewfinder through which the user can observe the target directly without offset; the framed image is captured by the built-in camera. We also present a user study that evaluates ClearPlate performance in the 2D barcode acquisition task. Results show that ClearPlate significantly outperforms the camera-phone-based approach with regard to 2D barcode acquisition.

Chigira, Hiroshi, Maeda, Atsuhiko and Kobayashi, Minoru (2011): Area-based photo-plethysmographic sensing method for the surfaces of handheld devices. In: Proceedings of the 2011 ACM Symposium on User Interface Software and Technology 2011. pp. 499-508.

Capturing the user's vital signs is an urgent goal in the HCI community. Photo-plethysmography (PPG) is one approach; it can collect data from the finger tips that indicate the user's autonomic nervous system (ANS) and offers new potentials such as mental stress measurement and drowsy state detection. Our goal is to set PPG sensors on the surfaces of ordinary devices such as mice, smartphones, and steering wheels. This will offer smart monitoring without the burden of additional wearable sensors. Unfortunately, current PPG sensors are very narrow, and even if the sensor is attached to the surface of a device, the user is forced to align and hold the finger to the sensor point, which degrades device usability. To solve this problem, we propose an area-based sensing method that relaxes the alignment requirement. The proposed method uses two thin acrylic plates, a diffuser plate and a detection plate, as an IR waveguide. The proposed method can yield very thin sensing surfaces and gentle curvatures are possible. An experiment compares the proposed method to the conventional point-sensor in terms of LF/HF discrimination performance with the participant in the resting state, and the proposed method is shown to offer comparable sensing performance with superior usability.

Nakashige, Mutsuhiro, Kobayashi, Minoru, Suzuki, Yuriko, Tamaki, Hidekazu and Higashino, Suguru (2009): "Hiya-Atsu" media: augmenting digital media with temperature. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 3181-3186.

Despite the development of many types of telecommunication systems, it is still hard to convey various types of information in an expressive manner to a remote partner. Our research focuses on using variations in temperature to achieve this. Hiya-Atsu-Mouse, which we developed to implement this idea, is a mouse device with thermal capabilities; the device becomes warmer or colder to the user's palm or fingertip according to the "temperature" of objects on the computer screen. This article evaluates the thermal performance of the device. The comments made by users are collected. Finally, we introduce a practical Hiya-Atsu-Mouse and describe it in operation.

Ihara, Masayuki, Kobayashi, Minoru and Sakai, Yoshinori (2009): Human affordance. In International Journal of Web Based Communities, 5 (2) pp. 255-272.

Our final goal is to utilise a cognition viewpoint for the engineering of a better design of human communication tools. In this paper, we extend the concept of affordance to cover human-to-human communication and propose the novel concept of 'human affordance', which is afforded from humans, not artefacts. As one possible utilisation of the concept, we introduce the example of affordance in evaluating the strength of agreement/disagreement phrases. In text-based communication, it is important for mutual understanding to effectively afford information about how a person feels about the text itself. This paper presents experimental results on over/underestimation in understanding the strength of agreement/disagreement in text-based communication. The human affordance identified in typical agreement/disagreement phrases is analysed in order to explore how to better augment human affordance in text-based communication.
