The immense growth and enhancement of technology had expanded the development and implementation of numerous teaching methods. An interactive digital environment triggers the student’s imagination and understanding of the course as well as provides traditional learning by enriching various classroom activities via touch of the finger. This final year project focuses on the development of virtual simulation based laboratory for mechanical engineering field accessed via mobile applications. The project utilizes the System Development Life Cycle (SDLC) as the core approach of development. The interface system outlined in the design phase is based on the objectives, scope and background research on prior phases as well as act on the model for the source coding and simulation of the system prototype. The virtual laboratory application consists of five types of simulation test which are Tensile Test, Hardness Test, Charpy Test, Plate Rolling Test and Basic Oxygen Steelmaking Test. The application requires the user to register themselves and upon a successful login, the user is taken to the menu that contain of all the tests. The user is able to obtain a basic idea of the experiment through the introduction and media section while the laboratory section leads to the step by step procedure of the experiment that leads to the simulation and result of the experiment. This particular software learning based virtual laboratory encourages learning experience for the student via virtual laboratory and simulation of the actual experiments. Alternately, the virtual laboratory helps students to obtain some idea on how the actual experiment is conducted and at the same time become familiar with the equipment used.
Blindness is an area of inadequate the visual conception because of physiological or even neurological aspects. The partial blindness corresponds to the insufficient integration in the expansion of the optic confidence or perhaps visual center of the eye, and also over-all total blindness is the complete inadequacy of the visual light perception. Within this research, a basic, inexpensive, friendly user, sensible blind assist technique is developed to be integrated with the portability of both blind and even visually impaired people in a particular region. The presented work consists of a wearable apparatus is made up of the head hat to facilitate the blind particular person to get around single-handedly safely and securely in order to keep away from any kind of obstructions that could be experienced, even if mounted and also mobile phone, to avoid virtually any probable accident. The primary function of this product is the Ultrasonic sensing unit which is able to inform the blind people if there exist any specific obstacles or otherwise not around them along with the vibrating motor probably would informs the blind people who which negative are the obstacles located. In addition, by pressing the home or work button this system will straight away link to MIT app inventor and the app will send a signal to Google maps to guide the blind people to its desired location. The implemented system is fast, and easy to use and an innovative affordable solution to blind and visually impaired people in third world countries.
