April 2016, NHK World

An international TV program that introduced our recent research has been broadcasted by NHK World on 28th April, 2016. Now we can watch the online stream. It includes my interview and research history of development of Buru-Navi. Click here to play the video in a new window.
The Wonder of Senses ©Japan International Broadcasting Inc.,

We made a hands-on demonstration at SIGGRAPH 2014 Emerging Tecchnologies. It was the first time to carry the demo to the North American continent. If you missed it, you can find a very thought-provoking article of my interview, "Could “Force Illusions” Help Wearables Catch On? " written by John Pavlus, in MIT Technology Review. It provides Spanish and Italian versions (also Polish and Greek versions in other web portal).

Another interview "“Force Illusions” Could Help the Visually Impaired" written by Ayesha Salim, also uploaded in IDG Connect.


The size of the one-DoF force display (top one) is greatly decreased by 95% (to 18x18x37 mm3) compared with the earlier one. The weight of the one-DoF force display is greatly decreased by 92% (to 19 g). Using two orthogonally placed actuators allows the holders to feel a force sensation in the four or eight principal directions on the azimuth plane (bottom one).

Fishing game with Buru-Navi3

Are you satisfied with a nibbling sensation created by conventional fishing games? If not, try Buru-Navi3.

Vibration-Weight Illusion: Asymmetric Oscillation Distorts the Perceived Heaviness of Handheld Objects 2007-2008

In contrast, almost no heaviness perception change was observed in the anti-gravity direction.
