Problems - Solutions - Science Concepts
Early obstacle detection
Problem : Conventional blind sticks detect obstacles only after contact.
Solution : Ultrasonic sensor detects objects before physical contact.
Acoustic Wave Propagation + Reflection
Sound waves travel through air and reflect from objects (echo formation)
No distance measurement capability
Problem : Traditional aids cannot measure how far an object is.
Solution : Time delay of echo is used to calculate distance.
Time-of-Flight Concept
Distance depends on wave travel time (d = vt/2)
Real-time feedback system
Problem : No continuous environmental feedback for the user.
Solution : Buzzer generates sound patterns based on distance
Signal Transduction + Human Sensory Substitution
Physical data → electrical signal → auditory output
Motion of Detection of Objects (Rate of change of distance - Kinematics)
Succesive distance measurements detect motion trend
Spatial awarness
Vector Physics (Spatial Representation)
Position represented using magnitude + direction (Future Extension)
