Sensora

Inspiration

The idea for Sensora was inspired by the need to enhance mobility and independence for individuals who are visually impaired. We wanted to create a solution that helps users to navigate their surroundings safely and confidently.

What it does

Sensora is a pair of sunglasses designed specifically for blind and visually impaired users. Using ultrasound sensors, these sunglasses beep when the wearer approaches an object, alerting them to potential obstacles and helping them navigate their environment more effectively without needing to carry a cane around.

How we built it

We developed Sensora by integrating a sensor into the middle of the sunglasses. The sensors detect objects within around a meter and trigger auditory alerts for the user. .

Challenges we ran into

Sensor Optimisation: We worked hard to optimise the sensor range to avoid false positives and ensure sound alerts were clear in different environments.

Component Sourcing: We had trouble finding the necessary components, so we switched from our intended use of lidar to an ultrasound sensor for distance measurement.

3D Printing Issues: Our attempt to 3D print the sunglasses failed so another member had to leave to buy another pair of glasses. Fortunately, the second 3D print of the initial prototype managed to work.

Accomplishments that we're proud of

1. We were able to get a working prototype with all the basic features we have set for ourselves at the beginning of the project.
2. Although we all come from diverse working backgrounds, we were able to seamlessly cooperate together to accomplish the tasks in time.

What we learned

Component integration: We learnt how to combine several components into a single working device Team dynamics: We gained insights to each other's working backgrounds and expertise.

What's next for Sensora

SOS Button: We aim to incorporate an SOS button that allows users to easily call for help in emergencies. Object Recognition: We are researching the development of object recognition technology to provide users with more detailed feedback about their surroundings, further improving navigation. 180 Degree Spacial Mapping: We plan to implement 180-degree spatial mapping to enhance obstacle detection and improve users’ awareness of their surroundings, helping them navigate complex environments more effectively. Partnerships: We’re seeking partnerships with organisations that support visually impaired individuals to increase awareness and accessibility of Sensora. Compact Sensors: We plan to use smaller sensors that are less noticeable, allowing the sunglasses to blend seamlessly into everyday life without drawing attention to the user’s visual impairment. Discreet Feedback: Instead of audible beeps, we will implement vibration alerts to provide discreet feedback, ensuring that communication with others is less obvious and more socially acceptable.
