Pi Sense

St Mary's CE Primary School, Horsham – Years 4-6

St Mary's CE Primary School, Horsham: Pi SensePi Sight is an intelligent cane that communicates with other devices to inform blind, partially sighted or deaf-blind people of nearby hazards or congested areas, enabling them to navigate safely where social distancing requirements are in place or where new hazards are close by.

Many blind people are intimately familiar with certain routes, but when they change, such as through repair works or unexpected congestion, navigating can become difficult. The Pi Sight uses strategically located radio beacons to interact with other devices and alert the user to hazards, helping them find a safe alternative.

To help manage social distancing, we also developed Navi-Gate, a door entry management system. It tracks how many people go in and out of a door and illuminates a neo-pixel strip in proportion to the percentage of people allowed into the space. There’s also a large green light when people can enter and a red light when the space is at maximum capacity. If too many people enter, the red light will also flash and there will be an audible signal.

Navi-Gate also communicates with Pi Sight to convey the same information to those who are blind, partially blind or deaf-blind.
