Floor Plan-Agnostic Detection of Gait Speed Drifts Using Ambient Sensors
Marina Vicini, Martin Rudorfer, Zhuangzhuang Dai +2
Gait speed is a vital health indicator for older adults, as changes in gait speed can reflect physiological and functional decline. Ambient sensors offer a promising, privacy-prese…
GazeMoE: Perception of Gaze Target with Mixture-of-Experts
Zhuangzhuang Dai, Zhongxi Lu, Vincent G. Zakka +3
Estimating human gaze target from visible images is a critical task for robots to understand human attention, yet the development of generalizable neural architectures and training…
Integrating Temporal Context into Streaming Data for Human Activity Recognition in Smart Home
Marina Vicini, Martin Rudorfer, Zhuangzhuang Dai +1
With the global population ageing, it is crucial to enable individuals to live independently and safely in their homes. Using ubiquitous sensors such as Passive InfraRed sensors (P…
GazeTarget360: Towards Gaze Target Estimation in 360-Degree for Robot Perception
Zhuangzhuang Dai, Vincent Gbouna Zakka, Luis J. Manso +1
Enabling robots to understand human gaze target is a crucial step to allow capabilities in downstream tasks, for example, attention estimation and movement anticipation in real-wor…
Multi-Head Adaptive Graph Convolution Network for Sparse Point Cloud-Based Human Activity Recognition
Vincent Gbouna Zakka, Luis J. Manso, Zhuangzhuang Dai
Human activity recognition is increasingly vital for supporting independent living, particularly for the elderly and those in need of assistance. Domestic service robots with monit…
Action Recognition in Real-World Ambient Assisted Living Environment
Vincent Gbouna Zakka, Zhuangzhuang Dai, Luis J. Manso
The growing ageing population and their preference to maintain independence by living in their own homes require proactive strategies to ensure safety and support. Ambient Assisted…
