Laser communication has potential to solve the communication blackout problem during hypersonic flight of reentry capsule or hypersonic vehicles. The influence of ablation particles from thermal protection materials of the vehicles is an important factor for the laser communication design. This paper firstly estimates the basic parameters of ablation particles from previous experimental reports. On this basis, attenuation by Mie and Debye scattering is calculated. It is indicated that the attenuation caused by Debye scattering is far less than 1. And the attenuation by Mie scattering is obvious when the particle number density exceeds 104 /cm3. From the results in this paper, 5 dB redundancy corresponding to the influence of ablation particles is suggested for the laser communication system design. © 2025 SPIE.

Personal and Ubiquitous Computing 2024年第3-4期28卷 549-577页

There has been a proliferation of emotion-related interactive textiles in recent years. This research conducted a comprehensive scoping review of the literature on emotion-related interactive textiles design. In total, 75 design studies were identified from their abstracts and analyzed with social network analysis and text mining methods. These studies were categorized into different aims (emotion expression, emotion communication, emotion reflection, emotion regulation, emotional effect, emotional experience, and emotion analysis). This review also analyzed details of prototypes and experimental design, such as textile form, textile function, feedback mechanism, experiment method, evaluation scale, and empirical findings. Then we evaluated these studies based on the relationship of their research aim, textiles, emotion, interaction mechanism, etc. The findings suggest that interactive textiles can aid in emotion presentation, modulation, and creating unique emotional experiences. Interactive textiles, feedback mechanisms, and bodily interaction all serve essential functions and benefit emotional interaction. Last, this review reflected on the critical research directions of emotion-related interactive textiles, including connecting interactive textiles with biofeedback, designing interactive textiles with sensory feedback mechanisms, and increasing bodily interaction for dynamic emotion. Further, this research provided insights into the research gaps, from elaborating on the experiment and exploring the materiality of interactive textiles to concerning privacy and user acceptance. Interactive textiles bridge textiles and emotion together to aid emotional well-being in people’s daily lives. © The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature 2024.

This paper introduces a gesture control system that integrates augmented reality (AR) and eye-tracking technologies for the operation of a 3D-printed prosthetic arm. Within this framework, users wear AR smart glasses equipped with eye-tracking and near-eye display modules. The system recognizes the user's gaze on a variety of everyday gesture AR representations (including open palm, grip, pinch, and point) shown on the near-eye display module. Subsequently, it commands the 3D-printed prosthetic arm to emulate the observed gestures. This approach enhances the synergy between the prosthetic and the natural arm, offering individuals with a single-arm amputation a more organic dual-handed experience in their daily activities. © 2024 IEEE.

Background Subtraction-based Unlearned Hazardous Object Detection Algorithm for Ceiling Environments

引用

Journal of Institute of Control, Robotics and systems 2025年第4期31卷 334-342页

We propose a background subtraction-based algorithm that uses images from an RGB-D camera to detect unlearned hazardous objects in ceiling environments, thereby facilitating efficient ceiling exploration. We constructed a dataset by compiling various images of ceiling structures and employed the YOLOv8s-seg model to recognize ceiling components. Recognized ceiling structures and regions exceeding a specified depth threshold were designated as background and removed in the first stage. A U-map based on depth information was then used to detect object regions, which enabled the identification of various types of potentially hazardous objects. The positions of the detected objects were continuously updated using a Kalman filter based tracking model, and their relative positions were visually displayed on a 2D map. To validate the performance of the algorithm, we implemented it in a system and conducted hazardous object detection experiments in a ceiling-simulated testbed and an actual ceiling environment. The findings confirmed the applicability of the algorithm in real-world settings. © ICROS 2025.
