Title: Hiromasa Oku: Inventor in Optical Tracking and Information Presentation.

Introduction

Hiromasa Oku is an inventor based in Tokyo, Japan, whose work includes patents related to controlling lines of sight and presenting visual information on moving objects. He is associated with the University of Tokyo and has 5 patents.

Latest Patents

Oku’s listed patents include a line-of-sight direction control device and an information presentation device.

The line-of-sight direction control device is designed to expand the range of possible line-of-sight movement, particularly in the pan direction, while enabling high-speed changes. Its pan mirror rotates in both directions around an axis positioned substantially parallel to the line of sight. A tilt direction control section adjusts the tilt angle and scans the line of sight, while rotation of the mirror controls the pan angle.

The information presentation device tracks a moving object whose trajectory is not known in advance and directs a light beam toward it. By projecting rendered information onto the object, the device can present an image larger than the object’s surface area, using the afterimage of the projected light.

Career Highlights

Oku’s patent work addresses optical control and projection systems. His inventions describe ways to steer a line of sight and use light to display information on moving surfaces.

Collaborations

Oku’s listed coworkers include Masatoshi Ishikawa and Alvaro Cassinelli. His work is associated with the University of Tokyo.

Conclusion

Hiromasa Oku’s patents explore line-of-sight control and light-based information presentation, reflecting an inventive focus on optical systems and dynamic visual displays.
