Dentsu ScienceJam Inc developed a wearable camera that automatically takes a short video when the wearer becomes curious about something.

The camera, "neurocam," consists of a smartphone and a headset equipped with a brain wave sensor. The sensor measures brain waves. And based on the measurement results, the value of an index called "Curiosity Degree" is calculated. When the value exceeds a certain threshold, the camera automatically starts shooting a five-second video (GIF animation) and saves it.

In addition to video, the camera records time and location information and allows the user to check it later or share it with friends. The camera was exhibited at Human Sensing 2013, a trade show that took place from Oct 23 to 25, 2013, in Yokohama, Japan.

The key members of the team that developed the neurocam are from "neurowear," a project team that developed the "necomimi" brain wave-based communication tool. The technology of calculating the value of the Curiosity Degree index was developed with help from Yasue Mitsukura, an associate professor at the Faculty of Science and Technology, Keio University.

The value was calculated based on the "Interest Degree," "Favorite Degree" and so forth, said a staffer at the trade show.

The brain wave sensor is a product of NeuroSky Inc.
