The document outlines a project by students at the Institute of Technical Education College East to develop a "Visually Handicapped Distance Sensor" to help visually impaired people avoid obstacles by detecting objects and providing audio feedback. It describes the current issues faced by the visually impaired, brainstorms solutions, and provides details of the working prototype which uses an ultrasonic sensor and buzzer connected to an Arduino board. The document also discusses improving the design in future phases to install additional sensors and features to further assist visually impaired users.

4. Current Situation
In our society, a minority number of people are visually Impaired and handicap having difficulties with
movement and facing obstacle.
Though documentary, we notice that a number of Singaporean facing difficulties (e.g total blindness,
partial blindness)
Usually visually Impaired or handicap people uses walking stick to feel the ground when they are
walking.They can feel the pole with their stick but doesn’t feel what’s above their body length.
Brainstorms
•Detect solid and nor solid
•Voice Communication
•Read material for feedback
•Visually Handicap Distance Sensor

5. We chooseVisually Handicap Distance Sensor (name of project) as our project to help several eye problems that become more
common among people as they age, although they can affect anyone at any age. Our aim of our project is to minimise the
accident of the visually challenge people form banging into solid object.
Our product can be used indoor and outdoor. Nowadays people like us challenge their self to feel how it’s like to have dinner in
the dark.

10. • Convenient
• A lot of features e.g.
Facebook
• It has a Bluetooth that saves
battery.
• Audio jack for privacy

11. • It needs programming
• Expensive
• Bluetooth Sheeld is not sold in
Singapore
• Only android phones can be
connected to sheeld
• At only one time, one language
can be produced

12. Future Improvement
Since our product is Phase 1, we would like to improve further and create a more solid
design to assist Visually Impaired and handicap users. These are the following
recommendations:
Phase 2
 To implement installing it at the walking stick to focus on near ground region and
knee region because our phase 1 covers mostly the upper body.
 We can install a Vibrated Motor for the blind and deaf. This would enable the user to
feel whether they are approaching a solid object or not.
 To install an on-off switch. This would enable to save battery life.

13. Phase 3
 We can install a micro chip sensor to transmit and receive the signal back when the
user reaches a traffic light pole. This would enable to know where the user location
and also the direction of the next traffic light pole.
 We can install more languages option. This will benefit the user as it is convenient to
them to understand
