  • Researchers invent interactive 3D holograms you can touch

    Using a system of lasers, mirrors and cameras, researchers at the Digital Nature Group (DNG) have invented a way to project three-dimensional holograms made up of tiny points of light called voxels that respond to human touch. Creating these special types of interactive holograms involves the use of lasers that transmit bursts of energy that last from 30 to 270 femtoseconds. According to principal investigator Yoichi Ochiai, touching the hologram feels like sandpaper (or for some like static electricity) that, due to the shortness of the laser bursts, are safe to touch. Dancing holograms and the sense of touch The three-dimensional images...

  • TomTom Runner Cardio review: it’s all in the wrist

    The TomTom Runner Cardio came to me at exactly the wrong time. You see, I usually run around four times a week, with a race frequently thrown into the mix. A combination of overseas travel and a chest infection (brought on by said overseas travel) meant that's how many times in total I was able to run during the review period. Still, I put it through its paces as best I could and, for the most part, the future looks pretty bright for performance wearables. Before we get into the review proper though, a little background: a couple of years...

  • Grafting your own ‘Call of Duty’ tournament: an interview with Jozi Underground

    It's no real surprise that gaming is growing both internationally and locally. All over the world, gamers are turning their hobbies into fierce competitive duels for glory and sometimes a little more. For those who aren't eSports hot shots, even the smaller tournaments are events to look forward to. When considering eSports globally though, the figures in general will scare you. DotA 2's The International boasts a current crowdfunded prize pool topping US$14-million, and is easily one of the more lucrative global eSports tournaments out there. The more you look at the competitive gaming scene the more you realize that there's a...

  • Samsung develops new battery tech based on silicon, graphene

    The one issue that marred the otherwise stellar Samsung Galaxy S6 was its paltry battery life, but it seems that the company responsible has quickly found a possible fix. A Samsung-funded project has made an interesting breakthrough in silicon-based battery technology, which is said to result in up to 1.8-times the capacity of a similarly sized lithium-ion battery -- the tech currently used in modern smartphones. After 200 charges, this only drops to 1.5-times, which is where the real improvement can be seen. The thesis is a dense one, but the takeaway is simple. Previous attempts at silicon-based batteries suffered from "large...

  • ‘Kirby and the Rainbow Paintbrush’ review: the Wii U’s most beautiful platformer, ever

    The Nintendo Wii U is a strange, strange machine that I still haven't really gotten to grips with yet. But for all its faff and fumble, it does have a few dynamite games. And by dynamite I mean small packages exploding into hugely expansive, absorbing and entertaining romps through the realms of Nintendoland. Although Nintendo has a habit of rehashing old titles, making a living off its legacy characters, it does produce a few beautiful gems once in a while. With that said, it's safe to say that Kirby and the Rainbow Paintbrush is one of those memorable few. Look, a...

  • Dream a little VR dream: Lucid Trips announces Whateverland

    Lucid Trips is a virtual reality (VR) game that, as its name suggests, is inspired by the mysterious and magical practice of lucid dreaming. It places you in a bodiless avatar that allows you to explore various vibrant and surrealistic planets in a large "VR dream universe". The creators (all members of the German VR Collective) describe it as a "Virtual Reality geo-caching experience". A few days ago (19 June) they announced their new art exploration game concept that takes place on their first dream planet dubbed Whateverland, an ethereal fusion that brings the world of art and lucid dreaming together. But...

  • OnePlus will reveal the OnePlus 2 in a VR showcase on 27 July

    If you're one of the many OnePlus One owners (or the many unable to obtain the device) waiting for the Chinese company to launch its new phone, there's some good news. A date has been set -- the 27 July 2015 -- for the big reveal of the OnePlus 2, but it not exactly like any smartphone launch we've seen before. The company will reveal the device using OnePlus cardboard VR headsets to reveal their latest smartphone, which the company deems is all in a ploy to "push the envelope." "Virtual reality holds a monumental amount of potential. With cutting-edge technology,...

    African device manufacturer Tecno has this week launched the Tecno WinPad 10 to the Nigerian market, which is the company's latest tablet hybrid to boast a decent specifications sheet and a smooth lick of style.

"We are indeed excited to bring this product to the...

  • ‘Call of Duty: Black Ops III’ will feature a zombie mode, according to Comic-Con schedule

    There are few things more certain in this world than a Call of Duty title with some type of zombie mode bolted on, and to reassert this notion, Activision and Treyarch will likely show off a zombie-tainted version of its next CoD offering -- Black Ops III -- at San Diego's ComicCon 2015. Thanks to a published schedule listing, we now have a fair idea of what Activision will be outing, which will likely be a trailer or gameplay depicting zombies running amok. You know, the usual fare. What's even more hilarious is the "Zombies director" title being handed to Jason...
