Realisation of a Virtual Reality based Remedial Module for Cognition and Hand Function Rehabilitation

Hand function disorders of an individual hinders them from performing activities of daily living with ease and sometimes limit their cognitive growth. As a remedial treatment, nowadays virtual reality (VR) emerged as a gaming platform that has been employed for the rehabilitation of such individuals. User motivation and engagement has risen with the development of VR technology. The developed remedial module is based on a VR platform using two games for upper limb rehabilitation with a hand motion sensing device (HMSD) to provide a solution for sensing hands and fingers movements. The movement was measured with the development of the games based on bilateral hand coordination and manual dexterity, the subset of Bruininks-Oseretsky Test (BOT2) of Motor Proficiency. However, the result of the system considered here is based on the system usability scale (SUS) for healthy individuals. Thus, the system is simple, economical, portable, user-friendly, and does not require intruding external hardware to wear. Hence, over the time these engaging VR rehabilitation games can provide an effective rehabilitation training process for upper limb hemiparesis children

A Haptic feedback system based on leap motion controller for prosthetic hand application

Leap Motion Controller (LMC) is a gesture sensor consists of three infrared light emitters and two infrared stereo cameras as tracking sensors. LMC translates hand movements into graphical data that are used in a variety of applications such as virtual/augmented reality and object movements control. In this work, we intend to control the movements of a prosthetic hand via (LMC) in which fingers are flexed or extended in response to hand movements. This will be carried out by passing in the data from the Leap Motion to a processing unit that processes the raw data by an open-source package (Processing i3) in order to control five servo motors using a micro-controller board. In addition, haptic setup is proposed using force sensors (FSR) and vibro-motors in which the speed of these motors is proportional to the amount of the grasp force exerted by the prosthetic hand. Investigation for optimal placement of the FSRs on a prosthetic hand to obtain convenient haptic feedback has been carried out. The results show the effect of object shape and weight on the obtained response of the FSR and how they influence the locations of the sensors

Review of three-dimensional human-computer interaction with focus on the leap motion controller

Modern hardware and software development has led to an evolution of user interfaces from command-line to natural user interfaces for virtual immersive environments. Gestures imitating real-world interaction tasks increasingly replace classical two-dimensional interfaces based on Windows/Icons/Menus/Pointers (WIMP) or touch metaphors. Thus, the purpose of this paper is to survey the state-of-the-art Human-Computer Interaction (HCI) techniques with a focus on the special field of three-dimensional interaction. This includes an overview of currently available interaction devices, their applications of usage and underlying methods for gesture design and recognition. Focus is on interfaces based on the Leap Motion Controller (LMC) and corresponding methods of gesture design and recognition. Further, a review of evaluation methods for the proposed natural user interfaces is given
