Conventional haptic feedback devices that rely on rigid components to achieve multiple degrees of freedom (DoF) often result in bulky, complex systems that hinder natural movement and increase user discomfort. This study addresses these limitations by substituting rigid materials with flexible, fabric-based materials to develop a variable shape actuator (VSA). The VSA is designed to provide multi-DoF haptic feedback by integrating contraction and expansion mechanisms within a lightweight, fabric structure. The actuator consists of a tactile feedback actuator (TFA) for delivering tactile sensations and a joint angle actuator (JAA) for kinesthetic feedback, allowing the system to dynamically alter its shape. Experimental results demonstrate that the VSA successfully produces multi-DoF haptic feedback on the palmar surface of the hand, enhancing the haptic experience in virtual environments. This advancement in haptic feedback technology paves the way for more diverse and immersive feedback systems, significantly narrowing the gap between virtual reality and physical reality.

Trust in agents within Virtual Reality is becoming increasingly important, as they provide advice and influence people's decision-making. However, previous studies show that encountering speech recognition errors can reduce users' trust in agents. Such errors lead users to ignore the agent's advice and make suboptimal decisions.

The history around teleoperation and deployment of robotic systems in constrained and dangerous environments such as nuclear is a long and successful one. From the 1940s, robotic manipulators have been used to manipulate dangerous substances and enable work in environments either too dangerous or impossible to be operated by human operators. Through the decades, technical and scientific advances have improved the capabilities of these devices, whilst allowing for more tasks to be performed.

Peripheral nerve injuries, especially those with complete transection of major nerves, create significant morbidity including debilitating pain, loss of protective haptic feedback, and impaired volitional control of musculature. The societal burden and cost of medical care for these injuries are enormous, with estimates in the United States alone in excess of $670 million per year. In clinical scenarios with a segmental nerve gap where end-to-end coaptation without tension is not possible, a "bridge" or scaffold must be interposed to facilitate communication between the proximal and distal stumps to facilitate organized growth following Wallerian degeneration.

With encountered-type haptic feedback, users can perceive a more realistic sensation for exertion interaction in substitutions reality. Although substitutional reality has utilized physical environments, props, and devices to provide encountered-type haptic feedback, these cannot withstand the fierce force of humans and do not give feedback when users move around simultaneously, such as in combat sports.
