What?

Thiea Vision is a start-up that aims to help people living with visual impairments navigate the world. It is a phone app that uses a neural network to process a video feed from a wi-fi enabled camera and convert it into audio feedback.

When it comes to navigation, the biggest obstacle is fear

Why?

Total loss of vision in both eyes is considered to be 100% visual impairment and 85% impairment of the whole person.

How?

By using TensorFlow, a framework for designing deep neural networks to to identify objects.

System Development

Surveys, Interviews, Literature reviews, and empathic modelling were used to develop the system. I personally spent two days with a blind fold in an attempt to better understand the problems that people with visual disabilities face.

So what did people have to say?

Biggest Problems:

Best Solutions

We used the insights gained from the surveys and questionnaires to decide on the different features the app would have.

Screens

User Experience

The biggest challenge with this project was to translate raw data (bounding boxes and probability percentages) from the neural network into a user-friendly format. Based on user feed-back, 5 modes were chosen: Navigation, Object Detection, Currency Identification, Object detection, and Text to Speech.

Design

The app was designed to be used by people with visual disabilities. To make it as easy as possible, minimal and large text, along with a range of bright colors for each screen were used.

Micro-Animations were designed with the intent of optimizing the user experience for people with low vision.

Development

We decided to design a product that would be mounted onto the user’s glasses as this would provide the best field of vision for the software.

CAD models

Various CAD models and physical prototypes were developed before the design was finalized.

Assembly

The body is made of machined aluminum with copper rings to hold the lens in place.

Docking

Hiding in plain site

The moment we decided to design a product that was mounted on to glasses, we knew it would be impossible to make the product invisible.

We decided to make the product a fashion accessory instead to make it something that users would be proud to wear.
