Japanese researchers at Aerial Burton have developed new technology that can project text and images in the sky without using a screen.
According to DigInfo:
"The images are constructed by firing a 1kHz infrared pulse laser into a 3D scanner, which reflects and focuses the pulses of the laser to specific points in the air. The molecules at that point are ionized, and the energy is released as photons."
The company thinks that the device could be used in emergency situations to relay information. Or maybe we can just use it to summon Batman?
The arm was created by Enabling the Future, which has a chapter at Sienna College in Albany, New York. For its first project the Siena e-NABLE group made an Iron Man-themed hand for 5-year-old Jack Carder in Ohio.
In this case, nine-year-old Karissa Mitchell's (who was born without a right hand and most of her wrist) mother reached out to the group on campus, Siena College's director of marketing and communications said.
"She's watched the movie at least 100 times. We sing the songs all the time. We even have a karaoke machine that's 'Frozen'-themed," said Karissa's mother. The prosthetic was built using a 3-D printer and is comprised of 30 parts (it took near 30 hours to make).
To help Karissa achieve her dream of becoming a Disney princess, the team used "a pretty transparent ice blue color filament and added snowflakes to the forearm and her name with an Elsa crown on the cuff," said Alyx Gleason, the project lead and president of Siera e-NABLE. The arm also came with an Olaf LED light source.
Anyone who is in need of an arm or hand is encouraged to reach out to Siena e-NABLE.
