“…Haptic or force feedback joysticks have been used in collision-avoidance systems to help users navigate away from obstacles [24][25][26]. Haptic interfaces interact with a user's touch and kinesthetic systems through force or other mechanical stimuli [27] and passively or actively guide the user away from obstacles. The technologies have been tested in laboratory settings with computer simulation or virtual systems and subjects without physical or cognitive disabilities [25][26] and in a virtual reality environment with adults with cerebral palsy or postpolio syndrome [24].…”

Abstract-Many older adults in long-term-care homes have complex physical and cognitive impairments and have difficulty propelling manual wheelchairs. Power wheelchair use is restricted owing to safety concerns. Power wheelchairs with collisionavoidance features are being developed to enable safe and independent mobility; however, a paucity of information exists on interface features to help users navigate away from obstacles. We developed a system combining an interface with auditory, visual, and haptic feedback and a simulated collision-avoidance power wheelchair. This device allowed the investigator to stop movement of the power wheelchair when users approached obstacles and to deliver feedback to help them navigate. Five long-termcare home residents with mild or moderate cognitive impairments evaluated device usability, which included effectiveness, efficiency, and user satisfaction. Each resident used the device for six 1 h sessions. Observations, feedback interviews, and outcome questionnaires were completed during and after the sessions. We found the device effective in enabling residents to achieve basic driving tasks and self-identified indoor mobility goals. Furthermore, residents perceived workload to be low and were satisfied with the device. Residents also felt that the feedback was useful to help them navigate away from obstacles.

“…Fortunately for the success of electronically driven haptic displays distal attribution seems to happen under an extraordinary range of conditions [38]. Back-y-Rita's tvss enabled blind subjects to feel objects exterior to their bodies via substitution of vision by artificially produced vibrotactile patterns [4].…”

This paper surveys more than twenty types of tactile illusions and discusses several of their aspects. These aspects include the ease with which they can be demonstrated and whether they have clear visual analogs. The paper also shows how to construct equipment made of simple supplies able to deliver well controlled tactile signals in order to conveniently demonstrate four different tactile illusions.

“…To ensure the fidelity of the haptic feedback, there is one critical requirement for the haptic feedback interfaces: high update rate (300Hz -1000Hz) [18]. In order to provide the right feedback, the interaction between worker and virtual objects should be real-time detected and analyzed.…”

Muscle fatigue is defined as the point at which the muscle is no longer able to sustain the required force or work output level. The overexertion of muscle force and muscle fatigue can induce acute pain and chronic pain in human body. When muscle fatigue is accumulated, the functional disability can be resulted as musculoskeletal disorders (MSD). There are several posture exposure analysis methods useful for rating the MSD risks, but they are mainly based on static postures.
