Real-time Image Generation for Compressive Light Field Displays

With the invention of integral imaging and parallax barriers in the beginning of the 20th century, glasses-free 3D displays have become feasible. Only today—more than a century later—glasses-free 3D displays are finally emerging in the consumer market. The technologies being employed in current-generation devices, however, are fundamentally the same as what was invented 100 years ago. With rapid advances in optical fabrication, digital processing power, and computational perception, a new generation of display technology is emerging: compressive displays exploring the co-design of optical elements and computational processing while taking particular characteristics of the human visual system into account. In this paper, we discuss real-time implementation strategies for emerging compressive light field displays. We consider displays composed of multiple stacked layers of light-attenuating or polarization-rotating layers, such as LCDs. The involved image generation requires iterative tomographic image synthesis. We demonstrate that, for the case of light field display, computed tomographic light field synthesis maps well to operations included in the standard graphics pipeline, facilitating efficient GPU-based implementations with real-time framerates.United States.

Man-walker robot

In the Philippines, senior citizens comprise four percent of the total population. When people get older, they may need assistance in walking due to the onset of age related problems such as arthritis. There are also a lot of physically challenged people in the country that may benefit from such a device. There are various equipment available in the market for such purpose, such as a cane or walking sticks, but the group wanted to create a technologically advanced substitute that would allow those in need of assistance to have a sophisticated walker. The walker would consist of electronic and mechanical parts, and would be capable of supporting the user. It will be able to sense and avoid obstacles along a path and allow the user to choose from three different pre-set speeds. The battery operated walker will allow a person in need of walking assistance more mobility and freedom
