Tekken and Gran Turismo announced for PlayStation VR

PlayStation VR might be able to steal a march on its rivals with the news that two of its longest running titles are set to be available on the device.

During his press conference at Paris Games Week, Sony Computer Entertainment Europe president and CEO Jim Ryan announced that Tekken 7 and Gran Turismo Sport will be VR compatible ahead of PlayStation’s entrance into the consumer virtual reality market.

Details on the games’ actual VR experience are in short supply, but since nearly all previously announced PlayStation VR experiences are played in the first person, we can assume that this will have a huge impact upon how the games might look and feel. For now though, Sony has teased audiences with a gameplay trailer that doesn’t show VR functionality.

Sony also announced at the conference that it  currently has “over 200 developers” currently working on PlayStation VR titles.

Games already revealed by Sony for the device include: Robinson: the Journey — which casts the player as an explorer in a world populated by dinosaurs — and Until Dawn: Rush of Blood — a horror shoot-em-up developed exclusively for PlayStation VR. Another VR game that Sony announced is RIGS: Mechanized Combat League which, from the trailer, looks like a fast and frenetic first-person shooter.

Away from Paris Games Week, Sony has already confirmed a number of titles coming to PlayStation VR in 2016, including, Eve: Valkyrie, The London Heist, The Walk, Battlezone and Megaton Rainfall.

The PlayStation VR headset, formerly known as Project Morpheus, has no official release date or price, but it is expected to be released in the first half of 2016. Speaking to Bloomberg, Sony Consumer Entertainment’s president and global CEO Andrew House confirmed that the VR model is expected to be priced similarly to the PlayStation games console.

World’s first sonic tractor beam lifts objects using sound waves

Researchers from the Universities of Bristol and Sussex, in collaboration with Ultrahaptics, have built the world’s first sonic tractor beam that can lift and move objects using sound waves.

Details of the device, published in Nature Communications, describe how the tractor beam uses high-amplitude sound waves to generate an acoustic hologram that is capable of picking up and moving small objects. The technique comes straight from the pages of a science-fiction novel.

“It was an incredible experience the first time we saw the object held in place by the tractor beam,” said Asier Marzo, PhD student and the lead author of the study.

The tractor beam works by using 64 miniature loudspeakers to create high-pitch and high-intensity sound waves. The resulting waves surround the object with sound and this creates a force field that keeps the object in place. By carefully controlling the output of the loudspeakers the object can be either be held in place, moved or rotated.

Sriram Subramanian, professor of Informatics at the University of Sussex and co-founder of Ultrahaptics, which is also working on using ultrasound to bring touch to virtual reality, explained: “In our device we manipulate objects in mid-air and seemingly defy gravity. Here we individually control dozens of loudspeakers to tell us an optimal solution to generate an acoustic hologram that can manipulate multiple objects in real-time without contact.”

The researchers hope the tractor beam can be developed to serve a wide range of applications. They describe how the current device could be used to transport delicate objects and assemble them, without the need for physical contact, or a miniature version could grip and transport drug capsules or microsurgical instruments through living tissue.

Depending on the desired application the research team have developed three different shapes of tractor beams. The first is an acoustic force field that resembles a pair of fingers or tweezers. The second is an acoustic vortex, the objects becoming stuck-in and then trapped at the core and the third is best described as a high-intensity cage that surrounds the objects and holds them in place from all directions.

Although the concept of an acoustic force field has long been envisioned by scientists, engineers and science-fiction writers, this breakthrough represents the first realised version of a sonic tractor beam that can lift and move objects using sound waves.

Previous work on acoustic studies had to surround the object with loudspeakers, which limits the extent of movement and restricts many applications.

Last year, the University of Dundee presented the concept of a tractor beam but no objects were held in the ray.
