From the moment we wake up to when we hit the pillow to sleep, we are surrounded by technology. Over the years, the word "smart" has had different meanings. Today, many devices are made to be smart, i.e. smart watches can keep track of one's heart rate, walking steps and hours of sleep or smart pajamas that can read bedtime stories. All these inventions have one thing in common, and it is that they aim to make everyone's life more interactive and easy with the use of technology. The Light Matters Team goal is to design a smart lighting system to make the target users' life more convenient and enjoyable. With the LightWave system, people will have the ability to control any light inside their homes with an easy voice command.LightWave system follows a server-client architecture where the system is categorized into two parts: a switch unit and a central unit. Switch units are installed in every room of a building where as the central unit will be installed into one specific room. Users' voice commands are recorded and processed by the switch unit, then the switch unit will communicate with the central unit using radio frequency signals. The central unit acts like the server of the system and will execute the commands. Basic commands will be supported as well as light or sound alarm set up. Some of the possible risks can result in unwanted lags in system's response, programming challenges resulting in undesired command handling, and trivial risks like electric shock or mishandling of tools. The system has the potential to bring great benefits to its users by facilitating a convenient way of interacting with a lighting system that will make the user's day to day life worry-free.
Undergraduate Engineering students are required to complete a group-based, two-course capstone sequence: ENSC 405W and ENSC 440.  Groups form company structures and create an innovative product that potentially acts as a solution to a real-life problem.  This collection archives the following assignments: proposal, design specifications, requirements specifications, and proof of concept.
