Motion Sensing White Cane

SIDE Project: Motion Sensing White Cane

So what exactly is an Motion Sensing White Cane? A Motion Sensing White Cane is an intelligent assistive device designed to help blind and visually impaired individuals navigate their surroundings safely and independently. Unlike traditional white canes, this smart stick integrates an advanced sensor that detects vibrations when making physical contact. By combining traditional tactile guidance with modern sensor technology, the Motion Sensing White Cane provides real time feedback to the user, enhances spatial awareness, increases safety, and empowers users to move through their environment with greater confidence and independence.

1. 3D Printed Filament
2. WTVB01-BT50 Vibration sensor

The main body of the cane is made from cone-like structures that stack together to form the walking stick.

Design cone-shaped segments that can securely connect to each other.

Tips:

1. The cones should stack firmly so the cane remains stable during use.
2. The number of cones depends on the height of the user.

Example reference:

User Height/Number of Cones

5'0"

12 cones

You can adjust the number of segments to create a cane that reaches roughly waist height for the user.

Once printed, set the cones aside for assembly.

Next, print a ball-shaped tip that will attach to the bottom of the cane. This ball serves two purposes:

1. It allows the cane to roll smoothly across the ground, reducing friction and improving comfort while walking.
2. It houses the vibration sensor, allowing it to detect impacts and vibrations when the cane contacts the ground or obstacles.

Design considerations for the ball tip:

1. The ball should roll easily on different surfaces.
2. The interior should include space to mount the WTVB01-BT50 vibration sensor.
3. Include a secure opening or compartment so the sensor can be placed inside and protected.

Once printed:

1. Insert the WTVB01-BT50 vibration sensor into the housing inside the ball tip.
2. Ensure it is secured so it can still detect vibrations effectively.
3. Close or secure the housing if your design includes a lid or snap-fit enclosure.

Now assemble the full walking stick.

1. Connect the cone segments together from largest to smallest (or according to your design).
2. Make sure each segment fits securely to keep the cane stable.
3. Attach the ball tip with the sensor housing to the bottom cone segment.

Once assembled, you should have a complete modular white cane with an integrated vibration sensor.

In this final step, the vibration sensor inside the cane is connected to a mobile app so the user or a helper can monitor activity and receive feedback from the cane. This adds an extra layer of awareness and customization to the Motion Sensing White Cane.

First, place the microcontroller and communication module (such as a Bluetooth module) into a small 3D-printed protective box. This box helps protect the electronics from damage while keeping the device compact and portable. Secure the box to the cane so it stays stable during use.

Next, connect the vibration sensor to the microcontroller inside the box. When the cane tip touches the ground or an object, the sensor detects the vibration and sends a signal to the controller. The controller then transmits this data to the mobile app through Bluetooth.

Once everything is powered on, open the mobile app and pair it with the device. After pairing, the app can receive signals from the cane in real time. The app can be used to track vibration events, adjust sensitivity settings, or provide additional notifications if needed. Connect the device with a text to speech app so the user can receive these signals.

After completing this step, the Motion Sensing White Cane is fully assembled and connected. The user now has a smart assistive device that combines traditional cane navigation with modern sensor technology for improved safety, awareness, and independence.
