This paper describes the design of a digital fork and a mobile interactive and persuasive game for a young child who is a picky eater and/or easily distracted during mealtime. The system employs Ubicomp technology to educate children on the importance of a balanced diet while motivating proper eating behavior. To sense a child's eating behavior, we have(More)
We propose a fork-type sensing device, Sensing Fork, which detects children's eating behavior (eating actions and chosen food) and a smartphone game to address children's eating problems. This paper describes the design and implementation of the Sensing Fork prototype and the play-based eating game called Hungry Panda.
This paper presents the design and implementation of a wearable oral sensory system that recognizes human oral activities, such as chewing, drinking, speaking, and coughing. We conducted an evaluation of this oral sensory system in a laboratory experiment involving 8 participants. The results show 93.8% oral activity recognition accuracy when using a(More)
We present a fork-type sensing device called the Sensing Fork that detects the eating behavior of children (food choice and eating actions), and a smartphone game to address children's eating problems based on their eating behavior. This paper describes the design and implementation of the Sensing Fork prototype and a play-based eating game called Hungry(More)
To facilitate the collection of patient biosignals, designing extensible sensing devices in which sensor management is simplified is essential. This paper presents BioScope, an extensible sensing system that facilitates collecting data used in nursing assessments. We conducted experiments to demonstrate the potential of the system. The results obtained in(More)
BACKGROUND The increased rates of cardiovascular morbidity and mortality in patients with psoriasis are not adequately explained by traditional risk factors. Whether concomitant sleep disorders (SDs) modify the risk of cardiovascular disease (CVD) in patients with psoriasis remains unknown. METHODS Using the Taiwan National Health Insurance Research(More)
Ketamine is an addictive drug that has been shown to inflict considerable physical and mental damage on users. Due in part to its low cost, ketamine has become one of the most popular club drugs among young adults and teenagers in Southeast Asia. This paper proposes a phone-based support system (KeDiary) with Bluetooth-enabled device for the screening of(More)
This paper describes the challenges and lessons learned in the design of a patient monitoring and early warning system for patients in acute psychiatric centers. We began by conducting contextual inquiries and a focus group to identify the challenges and opportunities for the application of new technologies. The resulting themes were then used in the(More)
This paper presents <i>fStrip</i>, a wearable device, which enables the use of tangible-and-deformable interface on-demand for mobile tasks. <i>fStrip</i> consists of an array of strain gauges for shape reconstruction, a 9 degrees-of-freedom inertial motion unit (IMU) for motion input, and an optional strip display for visual output. We present the(More)
This paper proposes a phone-based support system to enable drug-addicted patients to maintain abstinence after completing drug withdrawal treatment. Through a customized saliva screening device and patients' mobile phones, the self-administered saliva tests and support functions provided by the system can facilitate self-monitoring and managing in daily(More)
