<h2> Introduction and Motivation </h2>
<div class="text">
<p> Welcome to our project website featuring the Haptic Belt, an accessible device designed
to help individuals with mobility challenges navigate unexpected surface elevation changes. Our device aims to
address a significant problem faced by many individuals, including those with walking disabilities, the visually
impaired, and people with limited range of motion. The Haptic Belt detects changes in the walking surface and
sends LED and vibrational feedback to notify the user when a surface change is coming up, reducing the risk of
falls and injuries. Through a needfinding study, we found that there is a need for a discrete, portable, and
intuitive design that allows users to change which alerts go off. We also discovered that there are few similar
devices on the market, making the Haptic Belt a unique solution to a common problem. Our device can be used in a
wide range of scenarios, including non-uniform terrain and situations where vision is impaired, such as dark rooms
or outdoor environments. We also recognize the importance of connecting sound alerts to headphones using Bluetooth
for individuals with impaired hearing. With the Haptic Belt, we hope to create an accessible device that can help
mitigate the dangers of unexpected surface elevation changes for individuals with mobility challenges. Join us on
this journey as we work towards making walking safer and more accessible for everyone.

<p> To develop the haptic belt we used a breadboard to connect an Arduino to a 9V
Battery, two LEDS, an ultrasonic sensor, a transistor and a DC Motor.
Using the code on the left, we were able to program the Arudino to recieve input from the ultrasonic sensor
and calculate the distance to the floor.
If that floor exceeded a certain threshold, the Arduino would send a signal through its output pins to turn on
the red LED and the DC Motor, otherwise it would turn on the green LED.
The transistor was necessary to allow the Arduino to power the DC Motor because the Arduino could not provide
enough current to power the motor.
All the components were then placed in a belt bag and the ultrasonic sensor was allowed to hang out of the bag
to detect the floor.

<h2> Conclusion and Future Work </h2>
<div class="text">
<p> In conclusion, the haptic belt aids pepople with disabilities such as visual impairments as well as those
with restricted vision navigate their surroundings and avoid tripping due to changes in elevation.
The proposed additions with built-in belt sensors, LIDAR technology, and sound alerts
connected to headphones via Bluetooth would provide a reliable and efficient system for monitoring and controlling
height inputs during physical activities. However, there would still some challenges that need to be addressed,
such as adjusting sensors for people with different heights and connecting the hardware with new software
techniques. In the future, a phone app could be developed to interface with the hardware and provide more
control over the system, including light and sound options. Additionally, offering different belt colors and
designs could make the hardware more appealing to a wider range of users. By implementing these future steps and
addressing the challenges, this hardware solution could provide an excellent tool for individuals seeking to
track and improve their physical activity performance. </p>
