The Smart White Cane

Parts

Handle

We designed a very ergonomic, visually pleasing and extremely usable handle.

The cane can be used for long periods of time without feeling sore and hurt thanks to it's relatively lightweight. The handle weighs less than 300G, and most of it come from the 10000mAh battery that can be easily swapped.

An HC-SR04 Proximity sensor is placed in the front of the handle, tilted by a 45 degree angle for more natural obstacles detection.

Control buttons are placed on the top of the handle, close to the thumb for easy use. Each button can do multiple tasks.

Three LEDs are placed in different regions of the handle:

  • Red LED: Lights up when the battery capacity drops under 20%, a vocal warning will frequently play in the mobile app.
  • Green LED: Lights up when the cane is on.
  • White LED: Can be controlled using the middle button, it is used to make the user more visible in night and dim areas.

Buttons

The GuideMe have 5 buttons placed on top of the handle, they are used to control and navigate the mobile app.

The buttons board is connected to the main board using jumper wires, the design can be updated to use a flex cable or different type of connectors.

Three types of clicks can be detected:

  • Simple & Quick click
  • Long press (>1000ms)
  • Double click (Two quick clicks in less than 200ms)

Depending on the type of the click, each button can execute different task. Thanks to the simplicity of the app, double click was never needed, and all tasks were able to be executed only using single or double click.

Cane

A foldable cane can be screwed to the handle using the thread in front of the cane.

The cane consists of three parts that can be joined together, inside of which runs an elastic band that keeps the parts together when folded.

  • Master Stick: Screws to the cane in the top and can be connect to other slave sticks.
  • Slave Stick: Each of them measures 15cm and have a male and female connector on each side so you can connect multiple of them together to make the total height longer.
  • Tip: Connects to the bottom of the cane, to give more surface area, make sliding smoother and protect the cane from degrading due to friction
