Holovision aims at life-size 3D projections

Close on the heels of the 21st century complaint of “Where’s my jetpack?” is “Where’s my holographic projector?”. Nothing spells “future” like having a conversation with someone whose life-size image is beamed into the room.Provision of Chatsworth, California wants to bring that one step closer to reality, with its Holovision life-size holographic projector. The company is currently running a Kickstarter campaign aimed at raising US$950,000 to fund the development of new technology for the projector, with hopes of unveiling it next year.

The Holovision projector uses what is called aerial or volumetric imaging, which is a way of producing 3D images without special glasses, lenses or slits. It uses a digital LCD screen and a concave mirror to produce the illusion of a 3D image floating outside the projector. In the smaller versions currently made by Provision, this is about 30 cm (12 in) from the display surface, but in the life-size Holovision, this will be further. According to Provision, this technology produces a clearer image without generating multiple views or causing dizziness or nausea.

One of Provision's existing 3D projectors

Provision is already building 3D projectors as marketing tools, but the current Kickstarter program aims at advancing the technology. Currently, the company’s largest projector can only produce an 18-in (45.7-cm) image, but the goal is to create one 6 feet (1.8 m) tall that projects 7 ft (2.1 m) from the screen and is visible within a 100-degree arc. This will require developing new optics and a new light source. Once this is achieved, Provision plans to miniaturize the system to the size of a toaster for the game console market before expanding to applications in education, medicine, video conferencing and other fields.

The Kickstarter campaign runs through August 14 and the public debut of the system is scheduled for March, 2014.

Nerf Vulcan Sentry Gun tracks targets and avoids friendly fire

Anyone who plays video games will know that few things protect an area like a well-placed sentry gun. In the real world, though, even a person's bedroom or office could use a little protection sometimes, which is why one designer has built the Nerf Vulcan Sentry Gun. Using a custom program and some servos, the sentry can automatically locate targets and unleash a stream of foam darts at over seven times the usual speed, while keeping its owner out of the crosshairs. Britt Liv Ulrike Michelsen, a chemical and biological engineering student from Germany, designed and constructed the sentry using mostly basic electronics and some plywood. This isn't the first time she's modified a Nerf gun, but building this robotic turret is arguably her most ambitious project to date. Luckily, the Nerf Vulcan already operates using an electric motor, so controlling the actual firing mechanism through a computer was just a matter of connecting it directly to an Arduino Uno and a laptop. ...

Students crash rockets to develop new asteroid sample collection technique

In what at first glance seems like a terrible sense of direction, in March students from the University of Washington fired rockets from kites and balloons at an altitude of 3,000 ft (914 m) straight into the ground at Black Rock, Nevada: a dry lake bed in the desert 100 mi (160 km) north of Reno. This may seem like the ultimate in larking about, but it's actually a serious effort to develop new ways of collecting samples from asteroids. The test was part of the “Sample Return Systems for Extreme Environments” project. The idea is to find cheaper, more efficient ways of collecting samples from asteroids and hazardous areas on Earth, such as volcanoes and nuclear disaster zones, by using penetrators instead of soft landers or ground crews to hammer out sample cores. According to the team, this would result in lower cost than soft landing techniques by reducing the velocity and vehicle mass needed to gather the sample, minimizing damage on impact, as well as being mechanically s...

Stephen Hawking chooses a new voice

Celebrated Astrophysicist Stephen Hawking has selected and is using NeoSpeech's Text-to-Speech engine, VoiceText, as his new voice. VoiceText is integrated into Dr. Hawking's communicator, E Z Keys, enabling him to clearly communicate with the outside world. 'As a scientist and lecturer, it is imperative that Professor Hawking presents his findings in a clear and concise manner,' said Tom Pelly, Dr. Hawking's technical assistant. 'Professor Hawking was very impressed by NeoSpeech 's speech synthesiser, as it was by far the most natural-sounding and realistic of all of the off-the-shelf software voices that he has heard. This technology can help ensure that his vocals match his research in terms of credibility and believability.' Dr. Hawking, a renowned scientist, professor and author, suffers from Amyotrophic Lateral Sclerosis (ALS), a degenerative motor neuron illness. While the disease has not affected Dr. Hawking's intellectual capacity, ...
