Completed Projects

Emergencies have become a part of our everyday life. These emergencies usually take the form of sudden fire outbreaks, theft of property, high-way related crimes, road traffic accidents, illness and other health related issues. In the event of any of these occurrences, there arises the need to contact the relevant authorities or agencies to offer assistance. In this project, an Emergency Call System using Multiple Operator Enabled SIM has been developed. It is aimed at solving the difficulty and delay encountered in promptly reporting emergency situations which has over the years resulted in the loss of valuable lives and property worth billions of naira. With this system, call can be made with the use of the MOES card embedded based on the best network so as to avoid call failure. Interestingly, this device performs better than the existing GSM based emergency call systems due to its small time lag and its ability to establish a phone call to designated numbers with just a press of a button. Moreover, the system is very effective and reliable as it does not experience network failure and low quality of service (Qos).

Virtual Reality

The definition of virtual reality comes naturally from the definitions for both ‘virtual’ and ‘reality’. The definition of ‘virtual’ is near and reality is what we experience as human beings. So the term ‘virtual reality’ basically means ‘near-reality’. This could, of course, mean anything but it is usually referred to a specific type of reality emulation. Virtual reality (VR) typically refers to computer technologies that use virtual reality headsets to generate the realistic images, sounds and other sensations that replicate a real environment or create an imaginary setting. VR also simulates a user's physical presence in this environment. VR has been defined as "a realistic and immersive simulation of a three-dimensional 360-degree environment, created using interactive software, hardware, and experienced or controlled by movement of the body" or as an "immersive, interactive experience generated by a computer". A person using virtual reality equipment is able to "look around" the artificial world, and with high quality VR move about in it, and interact with features or items depicted in the headset. Virtual reality is displayed with a virtual reality headset. VR headsets are head-mounted goggles with a screen in front of the eyes. Programs may include audio and sounds through speakers or headphones. VR simulates real workplaces for occupational safety and health purposes. Information and projection technology are used to produce a virtual, three-dimensional, dynamic work environment. Within work scenario for example some parts of a machine move on their own while others can be moved by human operators. Perspective, angle of view, and acoustic and haptic properties change according to where the person is standing and how he or she moves relative to the environment. VR technology allows human information processing close to real life situations. VR enables all phases of a product life cycle, from design, through use, up to disposal, to be simulated, analysed and optimised. VR can be used for OSH purposes to:

  1. Review and improve the usability of products and processes whilst their development and design are still in progress. This enables errors in development and the need for subsequent modifications to be avoided.
  2. Systematically and empirically review design solutions for the human-system interfaces and their influence upon human behaviour. This reduces the need for physical modifications to machinery, and for extensive field studies.
  3. Safely test potentially hazardous products, processes and safety concepts. This avoids actual haza rds during the study of human-system interaction.
  4. Identify cause-effect relationships following accidents on and involving products. This saves material, personnel, time and financial outlay associated with in-situ testing.


Vehicle tracking system is a type of system that allows one to track the location of a car via wireless communication system, anytime and anywhere. The problem with the existing system lies in the fact that the use of GPS and CDMA trackers are very expensive while mobile enabled car trackers are very cheap. Another problem with mobile enabled car trackers is that of signal coverage. It is only applicable where a particular SIM that is on the network is available. Hence, this project is designed. It is aimed at solving the problem associated with vehicle or equipment tracking system that uses only 1 SIM and 1-transceiver. The MOES card embedded in it scans for the best network and makes its decision based on the best network to send information to the Network Control Centre (NOC) and the user. The developed MOES system was able to perform better than the existing GSM based vehicle tracking systems as it doesn’t experience network failure and low quality of service.
