PageFlip: Leveraging Page-Flipping Gestures for Efficient Command and Value Selection on Smartwatches
Teng Han,Jiannan Li,Khalad Hasan,Keisuke Nakamura,Randy Gomez,Ravin Balakrishnan,Pourang Irani +6 more
TL;DR: This work designs PageFlip, a novel method that combines into a single action multiple touch operations such as command invocation and value selection for efficient interaction on smartwatches and demonstrates novel smartwatch interaction opportunities.
Proceedings ArticleDOI
An Improvement for Video-based Heart Rate Variability Measurement
TL;DR: This paper proposes to use the slope sum function (SSF) to improve the interbeat interval (IBI) detection and shows that this new method has improved the accuracy of the HRV measurement in both frequency domain and time domain.
Journal ArticleDOI
Outdoor Sound Source Detection Using a Quadcopter with Microphone Array
Takuma Ohata,Keisuke Nakamura,Akihide Nagamine,Takeshi Mizumoto,Takayuki Ishizaki,Ryosuke Kojima,Osamu Sugiyama,Kazuhiro Nakadai,Kazuhiro Nakadai +8 more
TL;DR: The experimental results showed that the proposed iGSVD-MUSIC-CMS significantly improves sound source detection performance, and the prototype system achieves real-time processing.
Proceedings ArticleDOI
Hands-free human-robot communication robust to speaker's radial position
TL;DR: The synergistic effect of the two processes guarantee ASR performance improvement when used in conjunction with the authors' ASR-based dereverberation scheme, which significantly improved the RTF estimate robust to the speech power variation due to changes in speaker's radial position.
Proceedings ArticleDOI
Comparison of Region of Interest Segmentation Methods for Video-Based Heart Rate Measurements
TL;DR: Seven ROI segmentation methods are compared in the perspective of heart rate (HR) measurements with dedicated metrics and the algorithms are compared using the in-house database UBFC-RPPG, comprising of 53 videos specifically geared towards rPPG analysis.
