How Hitchhiker's Thumb Calculator works

The genome holds the blueprint of our body's architecture, including the shape of our thumb. Some people have a very "bendy" distal joint on their thumbs, called the Hitchhiker's Thumb. In fact, it is postulated that 1:3 people have this feature. Let's put this to the test by calculating the angle on your thumb and see how it compares with other people.

  1. You upload your image
  2. We run segmentation and image analysis algorithms over it to detect your thumb and distal joint
  3. From this we generate vectors to calculate the angle
  4. You learn how your thumb-bendyness compares to other people in the system
  5. PRIVACY: your original images will not be stored and the thresholded images are deleted periodically. Only the angle is retained long-term.

Example

Ready to upload your image

Simply upload an image of your thumb (Tip: uniform, high-contrast backgrounds work best).

Your angle is and you are in the percentile!

The Science behind Hitchhiker's Thumb Calculator

We put together a comprehensive article exploring the genomics behind the HitchhikersThumb and how we process the images. You can read the article on Medium.

We use scikit-image and Serverless Cloud Architecture.

To facilitate discussions during events we ask participants to submit their thumb land live-track entries. The top three thumbs are shown on the screen alongside the number and distribution of submitted thumbs. However, you will not be able to admire the images for long as we are deleting the photo itself soon after submission and only retain the angle due to privacy reasons.
