Immersion, interaction, and imagination are three features of virtual reality (VR). Existing VR systems possess fairly realistic visual auditory feedbacks, however, poor with haptic feedback, by means which human can perceive the physical world via abundant properties. Haptic display is an interface aiming to enable bilateral signal communications between computer, thus greatly enhance immersion interaction systems. This paper surveys paradigm shift occurred in past 30 years, classified into...

Bridging gap between and real world to enable ambient on various physical surfaces is a grand challenge field human-computer interaction. This paper presents concept an active electronic skin, characterized by three features: richness (multi-modal stimuli), interactivity (bi-directional sensing actuation capabilities), invisibility...
Abstract As a critical component in mechanical equipment, rolling bearings play vital role industrial production. Effective bearing fault diagnosis provides more reliable guarantee for the safe operation of output. Traditional data-driven methods often have problems such as insufficient feature extraction and poor model generalization capabilities, resulting reduced diagnostic accuracy. To solve these significantly improve accuracy, this paper proposes novel method based on multi-resolution...
Tactile devices composed of tactile pixels enable dynamic formulation surface morphological features. It, however, remains a challenge for soft to reliably achieve low-power control each pixel while maintaining high spatial resolution.

The capable pit depth without energy consumption. By simultaneously controlling current...
Soft actuators have been receiving tremendous attention as a result of their excellent adaptability to the environment. However, due inherently low stiffness, soft are difficult adapt high-load tasks. Despite previous efforts in developing stiffness-tunable by utilizing variable stiffness materials, they still suffer from limitations, including relatively load and locking capacity grasp weights difficulties regarding fabrication with complex structures. This work reports novel shape-locking...
Tactile devices provide an intuitive way for texture display, which allows users to perceive the detailed surface properties of virtual or remote objects. For existing tactile that create actual topographical transformations, it remains challenging render textures with high spatial resolution due limitation size actuators. To address this challenge, a magnetically responsive soft actuator diameter 1 mm is proposed. Integrating high-density array and membrane bracket, we develop device (named...
Pneumatic tactile displays dynamically customize surface morphological features with reconfigurable arrays of independently addressable actuators. However, their ability to render detailed patterns or fine textures is limited by the low spatial resolution. For pneumatic displays, high-density integration actuators within a small space (fingertip) poses significant challenge in terms circuit wiring. In contrast structure single-layer layout pipes, we propose multi-layered stacked microfluidic...
Error compensation is an important guarantee method to ensure the accuracy of clock synchronization in underwater sensor networks. Existing research methods mainly use linear fitting and least square compensate for parameters. Underwater wireless network nodes are mobile, which leads be always a time-varying state. In process synchronous forwarding, position where node sends receives data packets will change, resulting relative moving distance, leading dynamic delay increase in. this way, as...
