Background:
Bad posture is a serious issue that is prevalent in society. It feels natural to hunch over when doing work, studying, or even playing games. Along with this, bad posture is exhibited while sitting. Since these bad poses may happen subconsciously, it may be helpful to know when bad posture is being used.

Project:
Our project idea is to build a couch/chair that provides orthopedic feedback to the user. We spend a great portion of our day sitting down whether it be for work or leisure time. We figured that we might as well create some sort of system that informs the user of posture habits and potential orthopedic hazards. Our idea is in its preliminary stages, so we are open to further developing our scope for the project. The chair will be embedded with pressure sensors on its seat and its back. The pressure readings from the glutes, lumbar and upper back will be used to evaluate the posture of the user. Along with this, we can mount a range sensor on the back of the chair to measure the distance between the user and the back since slouching tends to increase that distance. Our project is an innovation, and the most similar thing we could find is a product called Axia Smart Chair. It is a chair that provides the user “direct feedback by means of a vibration signal in the seat cushion and a personal App”.

Featured Project

There is a drastic lack of networking infrastructure in unstable or remote areas, where businesses don’t think they can reliably recoup the large initial cost of construction. Our goal is to bring the internet to these areas. We will use a network of extremely affordable (<$20, made possible by IoT technology) solar-powered nodes that communicate via Wi-Fi with one another and personal devices, donated through organizations such as OLPC, creating an intranet. Each node covers an area approximately 600-800ft in every direction with 4MB/s access and 16GB of cached data, saving valuable bandwidth. Internal communication applications will be provided, minimizing expensive and slow global internet connections. Several solutions exist, but all have failed due to costs of over $200/node or the lack of networking capability.

To connect to the internet at large, a more powerful “server” may be added. This server hooks into the network like other nodes, but contains a cellular connection to connect to the global internet. Any device on the network will be able to access the web via the server’s connection, effectively spreading the cost of a single cellular data plan (which is too expensive for individuals in rural areas). The server also contains a continually-updated several-terabyte cache of educational data and programs, such as Wikipedia and Project Gutenberg. This data gives students and educators high-speed access to resources. Working in harmony, these two components foster economic growth and education, while significantly reducing the costs of adding future infrastructure.
