During the past decade, multi-touch surfaces have emerged as valuable tools for collaboration, display, interaction, and musical expression. Unfortunately, they tend to be costly and often suffer from two drawbacks for music performance: (1) relatively high latency owing to their sensing mechanism , and (2) lack of haptic feedback. We analyze the la-tency(More)
A system is presented for detecting common gestures, musical intentions and emotions of pianists in real-time using kinesthetic data retrieved by wireless motion sensors. The algorithm can detect six performer intended emotions such as cheerful, mournful, and vigorous, completely and solely based on low-sample-rate motion sensor data. The algorithm can be(More)
Few formal methods exist for evaluating digital musical instruments (DMIs). We propose a novel method of DMI evaluation using crowd-sourced tagging. Tagging is already used to classify websites and musical genres, which, like DMIs, do not lend themselves to simple categorization or parameterization. Using the social tagging method, participating individuals(More)
Recent studies by researchers, governmental agencies, and safety organizations have recognized a deficiency in the performance of medically related audible alarms [1–4]. In the clinical setting, care providers can suffer from alarm fatigue, a condition in which audible alarms in an operating room are perceived as a nuisance. In this study, we explore the(More)
The purpose of this study was to explore the relationship between mothers' depressive symptoms and the acoustic parameters of infant-directed (ID) singing. Participants included 80 mothers and their 3- to 9-month-old infants. A digital recording was made of each mother's voice while singing to her infant. Extraction and analyses of vocal data revealed a(More)
Motivated by previous work aimed at developing mathematical models to describe expressive timing in music, and specifically the final ritardandi, using measured kinematic data, we further investigate the linkage of locomotion and timing in music. The natural running behavior of four subjects is measured with a wearable sensor prototype and analyzed to(More)
