Story

What is your project about?

My project is a smart device box. It is the prototype version 1.0. This smart device is about imagining the future to help with comfort and accessibility. Creating a life and home not dependent on looking at phone screens. We are becoming too dependent on smart phones. As our home becomes more connected we have the opportunity to start building environments that establish how we stay digitally connected and organic at the same time. We can start using technology to help us with those that have disabilities and also helping us reconnect to nature.

I really decided to initialize this project when some of the conversations I recently had with people that are blind and have low vision. We were discussing how much light they need before entering a room. Imagine always feeling like going from a dark room to a room full of light you, your eyes will need time to adjust in order to find your way.

With my Portal box, it allows a user to find comfort, security and accessibility. A user coming home can initialize lights and other essential devices to be turned on by a sensor that will also continue to initialize as they move through their home space. The Portal box also allows a non user to notify the home owner that someone is at the door through a button being pressed and lights turning colors inside the premises. This initial portal will have two boxes. One which will sit at your front and another located in a safe place that sets up the network. Here are some images of the device working in a classroom setting.
