Spotted: How do you measure something when you cannot see the marks on a tape measure? This was the question faced by the developers of the Macaron. In response, they developed a measuring device that can be paired with a mobile app to provide audio measurements. The device was developed by a team from Queensland University, inspired by one of their members, who is visually impaired. The team has now formed a startup called Oseyeris, who are developing products for the visually impaired.

The Macaron is a measuring tape with a digital readout, which can be paired with a mobile app via Bluetooth. The device uses a soft and durable tape, with a spring-loaded hook. After users take a measurement using the Macaron, it is sent to the app, which can then tell them the precise distance. The tape uses a flip-out magnetic tip to enable precise positioning by feel, and the tip pushes down to straighten the measuring tape automatically. The measurements can be saved to the app by pressing a button. A haptic feedback vibration lets users know when the measurements have been saved.

At Springwise, we have reviewed a number of smart innovations designed to help the visually-impaired. These have included a 3D-printed tactile map and a wearable that can identify text and people. However, the Macaron is designed to enhance interaction, user experience and accuracy. The company’s long-term goal is to use universal design to eliminate the need for specialised products. They are aiming to create products which can be used by anyone, disabled or not.
