Review Paper On Wearable Computing Its Applications And Research Challenges. Acta Electronica Malaysia, 3(2) : 37-40 ARTICLE DETAILS Article History: Received 10 June 2019 Accepted 15 July 2019 Available online 7 August 2019 ABSTRACT Wearable technology provides number of opportunities in today’s world that trigged all the imaginations for the people. In today’s era we are more and more dependent on computers and to be compatible with the technology we have to be omnipresent and embrace new developments. Our daily use material is imposed by factor such as battery life, processor power, display brightness, network coverage and form factor have led to the delay in the widespread introduction of wearable computers. In this paper we will review wearable early design that was merely used for aircraft and military purpose and compare that with its today’s application that how nowadays they are used for personal activities. It also highlights the scope and market of wearable computers and how it is emerging day by day. KEYWORDS Wearable, computers, technology. 1. BACKGROUND Steve Mann, his invention of the ‘Wear Comp’ in 1979 gave invention to this concept of wearable computing. He created concept to introduced tiny computer only initially. Limitation of this initial invention was lightweight; height and high-speed processors and display devices were another Error [1]. The 1980s brought forward the development of the consumer camcorder, miniature CRTs etc. brought forward the development of the eyeglass mounted multimedia computer. As soon as the era of internet and wireless technologies arises it help a great deal in wearable computing. After the invention of wearable, it has pass through 18 generation of development and modification [2]. 2. INTRODUCTION However, in past 15 years wearable have successfully achieve its goal by implementing its applications that provide number of benefits, whereas in wearable computer operational and interactional constancy are the key features which brings allot of ease of communicating via using sensor- based devices to humankind [3]. We can refer it as device in which user can enter and execute set of commands while walking on ground or doing other activities .it can perform same function as mobile phones and laptops as well as other task that these handheld devices cannot perform. It is made in such a way that it could be easily worn constantly with the goal of becoming seamless extension of a body and mind that is connected to various sensors that are connected to our body to perform various function such as measure heartbeat, body temperature, walking speed etc [4]. due to its sensor technology wearable are more sophisticated that daily handheld devices. Wearable computing has introduced a new form interaction between human and computer comprising of a small computer part that can be easily worn and accessible and ready to use. It is just like becoming a superhero where you can be at more than one place at a time [5]. It’s like having superpowers like x-ray glasses, VR glasses and many more. A wearable is more than just a watch or regular glasses rather it acts like a whole computer system. The fact that differentiates a wearable device from a wearable computer is that a device is not programmable whereas wearable computer is reconfigurable and can be programed as needed [6]. This computer can perform equal numbers of computation as desktop or laptops. Computer to be wearable must pass 6 tests to be in the categorized as wearable computing devices [7]. 2.1 Test 1-Wearable These computers must be easily wearable for the certain of period of time. More ever easily come off. 2.2 Test 2-Smart Theses system must contain advanced circuitry, wireless connectivity and minimum level of independent capability for processing. 2.3 Test 3 This test should provide some information based on provided services. They must interact with user easily. 2.4 Test 4 Sensing and best cognitive support must be provided under this test. 2.5 Test 5 Attention should be reduced to provide high level of user privacy. 2.6 Test 6 They must be smart enough to maintain the balance between automation and computation and provide the user with the environment with his /her preference to work. 3. FEATURES OF WEARABLE COMPUTERS The features of wearable are as under 3.1 Consistency These systems run continuously and work in user friendly environment. Unlike PC and laptops, they don’t need to be open or closed.
