ANALYSIS OF HUMAN LIMBS MOTION BY DESIGNING WEARABLE WIRELESS DEVICE MESSAGE ALERT SYSTEM FOR VARIOUS APPLICATIONS PRASAD K. BHASME 1 & UMESH W. HORE 2 1M.E Student, Department of Electronics and Telecommunication, PRPCET, Amravati, Maharashtra, India 2Professor, Department of Electronics & Telecommunication Engineering, PRPCET, Amravati, Maharashtra, India ABSTRACT Motion sensing has played an important role inthe study of human biomechanics as well as the entertainment industry. Although existing technologies, such as optical orinertial based motion capture systems, have relatively high accuracy in detecting body motions, they still have inherentlimitations with regards to mobility and wearability. Most of the existing systems need wiring that commands the natural movement. In this project, to overcome this flaw, a wearable wireless sensor network with message status using accelerometers and flex sensor will be about to be designed in this undertaking. The wireless feature enables the uncontrolled movement of the human body as obstruct to a wired monitoring device & makes the system truly movable. Patient monitoring systems are gaining their importance as the fast-growing global elderly population increases demands for caretaking. These systems use wireless technologies to transmit vital signs for medical evaluation.Tracking of human motion has attracted significant interest in recent years due to its wide ranging applications such as rehabilitation, virtual reality, sports science, medical science and surveillance. In our project we will introduce the FLEX sensors, MEM sensors & GSM Technology. KEYWORDS: Flex Sensors, MEMS, GSM, Microcontroller INTRODUCTION As health awareness increases in society and technology continues to push its boundaries, there is an increasing demand for medical devices that provide around the clock assessment of a subject’s general well-being. These self-monitoring devices have the potential to dramatically improve a person’s health and productivity; thus improving the individual’s quality of life. Modern people have to deal with the fast-paced learning, work and life, facing more and more competition and challenges, and people with chronic illnesses such as heart disease become more and more. The ever-increasing rise in the number of chronically ill people is a growing burden on healthcare institutions. So in this disease, it is necessary to monitor Human Limb Motion along with Muscle temperature and heart rhythm. To achieve this mentioned, we are using this project to implement all that which helps in better and fast recovery of the patient. In recent years, magnetic &inertial tracking has fascinated much interest as they are the source-free approaches unlike the radar & audio that requires an emission source. The development of flex sensor technology & microelectro mechanical system technology had also made such sensors cheaper, lighter & smaller. In this project the FLEX sensors &MEMS sensors will be introduced into the application of medical & sports. The wireless feature activates the unrestrained movement of the human body as a counter to a wired monitoring device & makes the system truly movable. www.tjprc.org [email protected] 2 Prasad K. Bhasme & Umesh W. Hore Micro-Electro-Mechanical Systems, or MEMS, is a technology that in its most general form can be defined as miniaturized mechanical and electro-mechanical elements (i.e., devices and structures) that are made using the techniques of micro fabrication. The critical physical dimensions of MEMS devices can vary from well below one micron on the lower end of the dimensional spectrum, all the way to several millimeters.Likewise, the types of MEMS devices can vary from relatively simple structures having no moving elements, to extremely complex electromechanical systems with multiple moving elements under the control of integrated microelectronics. The small form factor and light weight feature of the sensor nodes also allow easy attachment to the limbs. Figure 1: Block Diagram Also, our project will be applicable to lots of other areas Figure 2: Functional Block Diagram RELATED WORK Yuan Luo; Hongmei Yang; Zhangfang Hu suggests their thoughts for Human limb motion real-time tracking based on Cam Shift for intelligent rehabilitation system and stated that the Intelligent rehabilitation system has become a hot topic. Considering the limb motion and selected color probability distribution all together, we put forwards the modified algorithm, which enhances anti-interference ability and avoids distracting. In conclusion, based on the Open CV computer vision library, use Cam Shift tracking algorithm to achieve limb motion tracking [IEEE International Conference on vol., no., pp. 343, 348, 19-23 Dec. 2009].[1] Fitzgerald et al also maintains information for the development of a wearable motion capture suit & virtual reality biofeedback system for the instruction & analysis of sports rehabilitation exercises & advised that the development Impact Factor (JCC): 5.3963 Index Copernicus Value (ICV): 3.0 Analysis of Human Limbs Motion by Designing Wearable Wireless Device Message Alert System for Various Applications 3 & design of a computer game for directing an athlete through a series of prescribed rehabilitation exercises.

[2] TRENDS IN OUR PROJECT This chapter gives the information of the trends in the sensor technology and the technology used in the project i.e. the flex sensor technology and gesture based technology. Sensor Technology Sensors allow detection, analysis, and recording of physical phenomenon that are difficult to otherwise measure by converting the phenomenon into a more convenient signal. Sensors convert physical measurements such as displacement, velocity, acceleration, force, pressure, chemical concentration, or flow into electrical signals. A revolution in micro fabricated sensors occurred with the application of semiconductor fabrication technology to sensor construction. By etching and depositing electrically conductive and nonconductive layers on silicon wafers, the sensor is created with the electrical sensing elements already built into the sensor. The products created using these techniques are called micro electro mechanical systems, or MEMS. The entire MEMS sensor is fabricated on a small section of a single silicon wafer or a stack of wafers bonded together. Reducing the area of the sensor layout both decreases the area of the sensor and increases the number of sensors produced on each wafer. The silicon dies are then packaged in chip carriers for use. Many types of inertial sensors have been fabricated as MEMS. The original MEMS sensors were pressure sensors using piezo resistive sensing elements, 2 while current MEMS sensors include accelerometers (measuring either linear 3 or angular4 acceleration), shear stress sensors, 5 chemical concentration sensors, 6 and gyroscopes. 7 This project uses single-axis MEMS linear accelerometer sensors fabricated at MIT to create a three-dimensional accelerometer sensor system suitable for measuring the acceleration of human hand motion. The focus of this project is measuring involuntary hand motion in people who have a significant hand tremor. Human hand motion can be broadly divided into two categories: voluntary and involuntary. Voluntary motion is intentional, such as throwing a baseball or changing the TV channel using a remote control. Involuntary motion is unintentional movement. One example of involuntary hand motion is the small vibrations in a person’s hand when they are trying to keep their hand still, due to small imperfections in the human body’s biomechanical feedback mechanisms. In healthy people this involuntary hand motion is small but measurable. Technology Used Flex Sensor Technology The Flex Sensor patented technology is based on resistive carbon elements. As a variable printed resistor, the Flex Sensor achieves great form-factor on a thin flexible substrate. When the substrate is bent, the sensor produces a resistance output correlated to the bend radius-the smaller the radius, the higher the resistance value. www.tjprc.org [email protected] 4 Prasad K. Bhasme & Umesh W. Hore Various sensor technologies are used to capture physical data such as bending of fingers. Often a motion tracker, such as a magnetictracking device or inertial tracking device, is attached to capture the global position/rotation data of the glove. These movements are then interpreted by the software that accompanies the glove, so any one movement can mean any number of things. Gestures can then be categorized into useful information, such as to recognize Sign Language or other symbolic functions. Expensive high-end wired gloves can also provide hectic feedback, which is a simulation of the sense of touch. This allows a wired glove to also be used as an output device. Traditionally, wired gloves have only been available at a huge cost, with the finger bend sensors and the tracking device having

  • Virtual Reality: What Is the State of Play in Education?
    Australian Journal of Educational Technology 1998, 14(1), 60-74 Virtual reality: What is the state of play in education? Colin Macpherson Central Queensland University Mike Keppell University of Melbourne Background The term 'virtual reality' (VR) is currently used to describe a range of computer-based systems in which a user can explore a hardware and software generated 'microworld' that bears some resemblance to reality. An early application of such systems was the flight simulator used to train pilots. However, it is in the area of hi-tech games that many of the more recent developments in this field have occurred. Typically, a user will wear a helmet containing either a small video screen positioned in front of each eye, or a device that projects images directly onto the user’s retinas. She might also wear an elaborately wired glove that provides tactile feedback as she attempts to physically interact with the computer- generated visual environment. It was on devices and systems of this nature that our proposed investigation was to concentrate. Although this has remained the case, we have expanded our work to also include VR that mainly uses screen-based graphics – thus reflecting the expanded definition of VR (more of which later). Overall aim Our overall aim was to determine the nature and capabilities of VR devices and systems that have already been developed, and of those that are under development; and to investigate the educational and instructional uses to which these devices and systems are already being put and to which they may be put in the near future.

  • Supporting User Interactions with Smart Built Environments
    Supporting User Interactions with Smart Built Environments Mohamed Hussein Hafez Handosa Dissertation submitted to the Faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Computer Science and Application Denis Graˇcanin,Chair Hicham G. Elmongui, Co-Chair Aisling Kelliher Benjamin Knapp KreˇsimirMatkovi´c December 10, 2018 Blacksburg, Virginia Keywords: Human-Computer Interaction, Internet of Things, Smart Environments Copyright 2018, Mohamed H. Handosa Supporting User Interactions with Smart Built Environments Mohamed Hussein Hafez Handosa ABSTRACT Before the recent advances in sensing, actuation, computing and communication technologies, the integration between the digital and the physical environment was limited. Humans linked those two worlds by collecting data about the physical environment before feeding it into the digital environment, and by changing the state of the physical environment based on the state of the digital environment. The incorporation of computing, communication, sensing, and actuation technologies into everyday physical objects has empowered the vision of the Internet of Things (IoT). Things can autonomously collect data about the physical environment, exchange information with other things, and take actions on behalf of humans. Application domains that can benefit from IoT include smart buildings, smart cities, smart water, smart agriculture, smart animal farming, smart metering, security and emergencies, retail, logistics, industrial control, and health care. For decades, building automation, intelligent buildings, and more recently smart buildings have received considerable attention in both academia and industry. We use the term smart built environments (SBE) to describe smart, intelligent, physical, built, architectural spaces ranging from a single room to a whole city.

  • The Presentation of Self in Immersive Virtual Environments
    The Immersive VR Self: Performance, Embodiment and Presence in Immersive Virtual Reality Environments Raz Schwartz, Research Lead, Oculus William Steptoe, Research & Software Engineer, Oculus Abstract Virtual avatars are a common way to present oneself in online social interactions. From cartoonish emoticons to hyper-realistic humanoids, these online representations help us portray a certain image to our respective audiences. Immersive VR systems like the Oculus Rift and HTC Vive track a user’s physical body movement in real-time and utilize this data to drive the corresponding behavior of an avatar. What is then special about avatars in immersive environments and how does this difference play out in the relationship between a user’s physical and virtual sense of presence? In this paper, we summarize academic research in this field, study the conditions that construct self- presentation in immersive VR, coin the term “immersive VR self” and detail its unique characteristics. Intro It was about 10:30am when I got a message from Will saying: “What are you up to this lunch break? Let’s go check out the new Oculus demo.” An hour later I was inside a dark demo room donning a Rift headset and holding a pair of Touch controllers. A few seconds later I was in ToyBox, a social VR experience that facilitates 1:1 interactions in immersive VR. I saw an avatar in front of me waving hello and then I heard the voice coming from the avatar’s mouth. The first few words were: “Hi Raz, how cool is this?!”. It was Will. I looked down and saw a graphic representation of my hands that matched my physical hand movement.
