Google Home - Brings Google Assistant into your house

Google Assistant

Google Assistant
Google has followed Amazon in announcing its own home hub device in the form of Google Home. The new device shares numerous features in common with Amazon's Echo device, which is yet to launch in the UK. Like Echo the device combines a Wi-Fi connected speaker with microphones for voice control, but it looks far more powerful thanks to Google's huge range of connected technologies, all of which work via the new Google Assistant technology.
Google Home looks like a small Bluetooth speaker, smaller than you might expect in fact, being easy to pick up single-handed. The lower section contains a speaker, with interchangeable bases so you can customise it to your home. It's the upper section that contains the clever bits though.
On top are a series of microphones to pick up your voice requests, based on this Google Home can play music, provide information based on requests and act as hub to control numerous other devices around your home. Voice controls are sent to Google's servers and parsed by the new Google Assistant technology. This is a chatty personal assistant which replies to your queries, through voice here but also via text on Android devices.

Review|LG 360 Cam

LG 360 Cam

LG 360 Cam

LG 360 Cam
When LG first unveiled its new LG G5 smartphone, it also announced that it would be releasing a whole load of companion ‘Friends’ devices to go with it. Admittedly, we didn’t have high hopes for the Friends line after the rather abysmal experience we had with its 360 VR headset, but thankfully, the LG 360 Cam is a lot more promising. For unlike the 360 VR headset, which is only compatible with the LG G5, the 360 Cam will happily work with non-LG Android phones as well as iOS device through its LG Friends Manager companion app.
From the outside, it doesn’t look too dissimilar from the Ricoh Theta S. Its comfy, upright design makes it easy to grip in one hand, and a pair of slightly bulbous 180-degree lenses sit at the top in opposite directions. The camera then stitches these images together to create a full, 360-degree sphere.
Its simple controls make it very easy to use. Apart from the shutter button, which sits well within reach of your thumb, the only other button is the power button along the side. There’s also a pair of LED lights that tell you when the camera’s set to shoot in 360-degrees (using both lenses) or just 180-degrees (which just uses the front lens).
You’ll have to supply your own microSD card, though, as the 360 Cam doesn’t have any onboard storage. Luckily, it takes cards up to 2TB in size, so you should have plenty of room when it comes to storing your footage.
Next to the microSD slot, you’ll find a standard tripod thread, so you can easily pop the 360 Cam on a tripod for extra stability. It will happily stand up of its own free will, but at least it provides you with a bit of flexibility. You can also use the 360 Cam with other action cam mounting accessories, such as sticky mounts, but you’ll need to use an adaptor if you’re using GoPro-style mounts.
Photo and Video Capture
Mounting the camera or placing it on a flat surface is probably preferable in the long run, as holding it manually can often mean your hands and arms end up obscuring a decent chunk of the frame. Fortunately, you can remotely control the 360 Cam remotely from the LG Friends Manager app.
This allows your smartphone or tablet to connect to the 360 Cam through a combination of Bluetooth and Wi-Fi. The Bluetooth connection lets the app wake the camera up from a low-power state, but Wi-Fi Direct is used to carry the live view output to your device and for transferring videos and photographs for sharing. It takes a few seconds to power on, but once I’d run through its initial setup, it became much quicker to use.
A short press captures a still image, while a longer press begins video recording, but you’ll need to use the app to change the camera’s various settings, such as putting it into timer mode. The timer mode setting is automatically saved to the camera, too, so you don’t need to dig out your smartphone to trigger it remotely when you want to take a 360-degree selfie.
The app also has an array of different preset modes, such as Night, as well as individual controls for manual exposure, ISO (ranging from ISO 50 to ISO 2700), shutter speed (from 1/2 to 1/6000) and white balance adjustments.
Each lens is capable of capturing 13 megapixel still images, but when these are combined to 360-degree photo spheres this amounts to a 16 megapixel image overall. Video can be captured at up to a resolution of 2,560x1,280, but annoyingly this is limited to just 20 minutes at a time, forcing you to manually begin recording again rather than simply start a new recording automatically.
That said, one distinct advantage the LG 360 Cam has over the Ricoh Theta S is that it’s natively supported by both Facebook and YouTube for 360-degree video uploads. You’re able to upload to both services directly from the app and they’re automatically recognised, making them much easier to share. You don’t need any separate tools to add in meta data, as it’s all recognised automatically as 360-degree content. 360-degree photographs are also natively supported by Google Photos, Google Streetview and Flickr.
That said, I found that if I uploaded videos to YouTube from the microSD card through a desktop browser, YouTube would stitch the two videos together rather haphazardly, showing a noticeable overlap of the two separate images. When I uploaded the same video through my smartphone, it uploaded perfectly fine with no overt stitching, so I’d recommended using the app to upload your video as often as possible.

Video quality

As for video quality, footage actually looks pretty great when viewed on your smartphone. Granted, it’s noticeably soft around the edge of the frame, but it’s certainly on a par with the Ricoh Theta S, as colours were largely accurate and there were good levels of detail. However, much like with the Ricoh Theta S, videos don’t look so great when uploaded to YouTube, which is a shame.
Set the 360 Cam to 180-degree mode, and you can get some interesting photographs. Although distorted, they have their own visual appeal, and photographs taken in the 360-degree mode results in even crazier pictures before you upload them to a compatible service. You can see what a proper photosphere upload looks like on Google Photos here, but arty types will no doubt have a lot of fun with its flat images as well.
As for battery life, I was able to capture video for about an hour and 20 minutes, which is actually quite good considering there are two sensors in play. It charges via USB-C, too, so it doesn’t take long to top up between shooting sessions.

Conclusion

At £100 less than the Ricoh Theta S, the LG 360 Cam is arguably the best 360-degree camera you can buy right now. Admittedly, there’s not a lot of competition out there at the moment, as precious few wide-angle cameras can actually shoot in 360-degrees. That might change when Samsung releases its upcoming Gear 360 camera, but this is only compatible with recent Samsung phones, putting it at a disadvantage compared to the wider compatibility of the LG 360 Cam.
Of course, whether or not you need a 360-degree camera is another matter. It’s certainly an interesting way to capture your surroundings, especially in a group scenario, and it’s also useful for estate agents and the like for more professional purposes. However, the quality isn’t particularly great compared to other capture cams I’ve tested, so unless you really want to capture 360-degree content, you’d be better off buying a GoPro camera such as the Hero+ LCD or the Hero4 Session.

Review|Nvidia Shield Tablet K1

Nvidia Shield Tablet K1

Nvidia Shield Tablet K1
When it arrived in 2014, the original Shield was a seriously powerful gaming tablet that packed in a lot of extra value if you happened to own an Nvidia graphics card. Unfortunately, a battery overheating issue forced the company to recall a large number of tablets, and eventually withdraw it from sale completely. The Shield Tablet is now back as the K1, a facelifted version with a battery that won't blow up unexpectedly.
·      What’s changed?
Battery aside, the differences between the K1 and the original Shield Tablet are mostly skin deep. You’d be hard pushed to spot the difference between the two; the K1 has a silver Shield logo on the rear rather than a shiny black one, the edges of the tablet are matte, rather than shiny, and the speaker grilles have a rubberised finish, rather than the plastic seen on the original. The ports, buttons and speakers are all in the same places too.
You don’t get a stylus with the K1, but while gamers are unlikely to miss it, anyone wanting to sketch or take notes can buy Nvidia’s DirectStylus separately for £15. There’s no docking mechanism to store it inside the tablet, however. There’s also no power adaptor in the box, which helps keep costs down. You’re almost guaranteed to have a micro USB cable lying around the house, but unless you have a 2A charger it could take a while to refuel the tablet once it runs out of juice. If you insist on having an Nvidia-branded cable and charger, you can pick up the pair for £18. There have been a few cost-cutting changes inside, too, simplifying the range by ditching the 4G LTE modem and the 32GB storage option. The K1 is only available in a 16GB, Wi-Fi only configuration. There’s still a microSD card slot for adding extra capacity, and when Android Marshmallow arrives it will be far better at handling external storage than Lollipop is at present.

·      Android Marshmallow

Nvidia's stayed true to its promise of regular Android updates for its Shield devices updating the Shield Tablet K1 to version 6.0 Marshmallow. It was a bit of a tumultuous update process with the company temporarily halting the roll out due to Wi-Fi bugs introduced in an earlier version. The good news is that those problems have seemingly been fixed, so you should expect the update to arrive in due course. 
One of the more important updates that Marshmallow brings is better management of external storage. Now when you add a microSD card, the operating system can more effectively integrate it with the internal storage, essentially treating them both as one and the same. On top of this, Nvidia has updated the Camera app with a new design that takes inspiration from Google's Material design language.
Other Marshmallow additions, such as Google Now On Tap, are also now introduced. Importantly, the update also brings with it support for the Vulkan API, which provides more efficient access to the Shield Tablet K1's graphics hardware. There are other plenty of smaller bug and performance fixes, too, including better power management so it's worth checking if the update has been rolled out to your device.

·      Performance

The K1 is almost identical to the original Shield tablet. It has the same Nvidia Tegra K1 quad-core processor running at 2.2GHz, 2GB of RAM and the incredibly fast Kepler SMX GPU, which made the original such a potent gaming machine. The Shield's chip is slightly different to the one found in Google’s Nexus 9, which is dual-core and 64-bit, but in practice there’s little performance difference between the two tablets.
A Peacekeeper browser benchmark score of 1,148 is on par with Samsung’s £400 Galaxy Tab S2, which helps make web browsing feel very fluid and responsive. GeekBench 3 single- and multi-core scores of 1,142 and 3,554 are also among the fastest we’ve seen from an 8in Android tablet, which helps Android 6.0 Marshmallow animate, open apps and multi-task smoothly.
With near-identical hardware, it was no surprise that the K1 turned in almost the exact same battery life score as the original Shield Tablet. At 12 hours 39 minutes, it’s among the better 8in tablets, but still falls slightly behind Samsung’s Galaxy Tab S2 and Lenovo Yoga Tab 3, which both managed over 14 hours. Even so, you’ll get a full day of use from the K1, and should manage over five hours when playing graphically intensive games.

·      Gaming

The Kepler GPU is one of the most powerful tablet graphics chips around, so it should come as no surprise that it excelled in the GFXBench GL Manhattan tests. Scores of 1801 (or 29fps) in the onscreen test and 1961 (or 32fps) in the offscreen test are second only to the iPad Air 2. There’s simply no other Android devices that are as fast. It shows in games like Blizzard’s Hearthstone, with battle animations looking incredibly smooth.
As a Shield device, the K1 includes access to Nvidia’s GeForce Now and GameStream services. The former provides unlimited access to 50 PC games, streamed from the cloud to your tablet, for £7.49 a month. The selection is mostly limited to older titles, with newer games like the Witcher 3 available separately at a premium, although they justify the extra cost by including a Good Old Games or Steam key for offline play.
GameStream is the free alternative that uses a PC equipped with an Nvidia graphics card to stream your games library locally over a wireless network. It works brilliantly if you have powerful enough hardware; Nvidia suggests a GeForce GTX 650 or higher desktop graphics card or a GeForce GTX 800M laptop GPU as the minimum for uninterrupted play. A dual-band 802.11n router is also recommended for 1080p streaming. It’s frustrating that Nvidia hasn’t added 802.11ac, but this was missing from the original tablet so it’s not a surprise to find it absent here too.
A controller, like the optional Shield Tablet Wireless Controller (£50, www.ebuyer.com), is essential for serious gaming. It connects via Wi-Fi direct rather than Bluetooth for lower latency, and for up to four-controller multiplayer gaming on a single tablet. The Xbox-style layout makes it ideal for console ports, but the built-in touchpad and volume control buttons are handy for mobile-focused titles too. A headset jack and integrated microphone let you use Android’s voice-operated features too.

·      Display and sound

It appears Nvidia has used the same display panel in the K1 as it did for the original Shield Tablet; both have a 1,920x1,200 resolution and relatively high pixel density of 283ppi. An sRGB colour gamut coverage of 79.2% was above average when the Shield first launched, but in a £150 tablet it’s a very respectable score indeed. Black levels remain rather high at 0.4cd/m2, and a contrast ratio of 823:1 wasn’t particularly high, but an above average maximum brightness of 434cd/m2 gives photos and videos plenty of punch.
Importantly, viewing angles are excellent, and while not earth-shattering, the panel is easily one of the best you’ll get in a £150 Android tablet.
The side-firing stereo speakers are still some of the best we’ve heard from a tablet, producing a clear mid-range and relatively crisp trebles. There’s even some semblance of bass presence, and stereo separation was noticeable in films and TV. You won’t need to reach for a pair of headphones for YouTube or Twitch videos, either, as the speakers are impressively loud.

·      Camera

The 5-megapixel cameras on the front and back produce fairly respectable images outdoors where there’s lots of light. Saturation is reasonable, but they were a little soft. The HDR mode left images looking a little washed-out, and there was still a lack of sharpness. The front-facing camera works surprisingly well indoors and in low light, as would be the most likely situation when streaming game commentary using the Shield’s Twitch integration.
