The Tricorder Project explores ways to make otherwise invisible aspects of the world easier to sense and understand. Its goal is to combine a diverse range of inexpensive sensors in an accessible, easy-to-use handheld device that can be carried in a pocket or bag. Rather than simply collecting measurements, the project emphasizes intuitive visualizations that help people perceive phenomena such as magnetic fields, temperature, and light polarization in ways that feel as natural as seeing color.

The project describes potential uses in imaging, science education, and environmental monitoring, while encouraging users to imagine applications of their own. Its site features the Tricorder Mark 1 and Mark 2, along with project background, development updates, and community resources, including a forum and blog. The Tricorder Project presents its work as an invitation to explore the world through sensing and visualization, bringing scientific tools closer to everyday experience.
