We’re also partnering with Pasco, so that you can turn the Education Editions into scientific instruments, so – right out of the box – they’re ambient noise sensors. You can run labs with noise and noise in different parts of the room, etc, and you can also attach over 70 sensors, microscopes, even a Geiger counter for radiation, and all the data is uploaded to the screens of the units, and there are lesson plans around each one.Q: So we’re moving away from the time when classroom devices were repurposed education versions of corporate or consumer devices?A: Absolutely, from the ground up, and the way that we designed them was by going to schools, talking to administrators, talking to teachers, even speaking to students, and that informed the design of these products, which are built specifically for education. They are not a retooled corporate or consumer offering.

Q: On the stand I’m seeing a lot of convertibles and tablets. Are you finding that these mobile devices are really making their way into schools?A: We think so. Kinaesthetic learning – learning by touching and feeling – is so important in the primary grades. We’re seeing a large amount of schools in primary education use technology in ways that really engage the students, and where they can really interact with content.Tablets are also highly mobile. With the new tablets, schools can choose between Android or Windows. The trend for tablets in education is really in primary. For middle schools and secondary schools we’re seeing Chromebooks, and there are lots of requirements for content creation, and a lot of times those include a keyboard.

Third-party developers should also be more mindful of these problems, argues Kirk: “Most think of accessibility as a solution for people who can’t see or hear, but it’s much more than that. Too many people are unaware of the problems associated with excessive onscreen motion, because they simply don’t suffer such problems.” Val counters that “creating animated interfaces is still new territory,” but agrees this doesn’t excuse designers and developers, adding that increased awareness of both upsides and downsides should help better decisions be made regarding where and how to add motion.James Thomson is a developer who recently added a setting to disable transitions in his calculator app, PCalc. Although he considers himself fortunate in not having to rely on accessibility features, “millions do, and anything that can be done to help more people use our apps and devices is worth it”.

“Increased awareness of both upsides and downsides should help better decisions be made regarding where and how to add motion.”
He suggests fancy graphical effects that have no actual purpose should be made optional: “It’s not difficult to do — replacing a full-screen swipe with a simple fade, for example. You just need to think about this during development and not tack it on at the end.” But James wonders how many developers consider accessibility at all, and suggests everyone in the industry needs to do better and recruit more diverse testers who will pick up those things development teams may miss.As for Apple, he sees no obvious technical reason for Reduce Motion, at the very least, becoming a part of OS X El Capitan: “Apple has already recognised on iOS that this feature has a benefit, and so I assume it’s a question of prioritising development time. But very small changes make a big difference to some people.” He ends by saying that with both upcoming system updates, it’s still early enough to get changes in before final versions are shipped: “So the best thing people can do is log bugs against the features in question.”

Yep, that’s right. Now Google has put its weight behind the security-cam sector with the new Nest Cam, many more people are going to want one in their home. Excited though you may be, before you stump up the £159 asking price for Google’s new product, I recommend you take a look at Netgear’s Arlo system instead. Why? Because Arlo may well be the smart home-monitoring system the search giant should have launched all along.Arlo is the successor to the Netgear VueZone system the company released last year. Just like the VueZone – and Google’s forthcoming Nest Cam – Arlo is an easy-to-setup and use home-monitoring system. Its cameras can record motion-triggered video clips to the cloud where they can be viewed at your leisure, and they can also stream live footage direct to your tablet, smartphone or laptop.In this sense, Arlo is no different from the thousands of other IP cameras on the market. However, Arlo has a killer feature: its cameras are battery powered.

This means you can place the cameras anywhere you like, without having to find a nearby mains socket to power it – or drill holes in your walls to run cables. It also means you can pick up the cameras and move them around whenever you fancy: you can pop a camera on a shelf to monitor baby when you put them to bed; then move it to the kitchen to keep an eye on the cat when you go away. (In fact, Netgear positively encourages this, supplying two magnetic hemispherical mounts per camera.)Netgear Arlo: Camera battery compartment
The cameras are even weatherproofed (rated to IP65), so there’s no need to purchase a separate case if you want to point a camera at your front door or keep tabs on the comings and goings in your garden.

The downside of this is that you’ll have to replace the batteries fairly regularly. Each camera takes four CR123 batteries, and a set will last you between four and six months, depending on the quality of video you’re recording and how often the camera is triggered.It’s also worth noting that these figures relate to “recommended settings and typical usage”; point the camera at your fish tank, the cat flap or a busy bird table while leaving motion detection on 24/7 and the batteries will likely run out much sooner. Still, this isn’t bad for a camera that records video at a resolution of 720p, and the Arlo cameras have a host of other advanced features I’d normally only expect to see on mains-powered IP cameras.For starters, each camera is equipped with eight infrared LEDs so it can see in the dark to a distance of 4.5m. And each one has a passive infrared sensor (PIR) of the kind used in burglar alarms, so it can capture motion-triggered footage while using very little power.

Even were there nothing else to recommend the HP Stream 11, its eye-catching design would win it plenty of fans. HP’s 11.6in, Windows 8.1 with Bing budget laptop comes in a choice of vibrant blue or magenta finishes, with a slimline chassis that measures just under 20mm thick and weighs only 1.29kg. That doesn’t make it the slimmest or lightest laptop around, but the plastics have been treated with a powdered matte finish that makes it feel more expensive than it is, and it feels more solid and robust.The design is stable and well balanced, both on the desk and on the lap. While we’re not completely sure about the graduated colours on the keyboard surround, there’s an irresistible sense of fun about the styling.The good news continues when you power it up. The 11.6in screen has the usual 1,366 x 768 resolution, but it’s one of the best displays on test, with decent viewing angles, a maximum brightness of 261cd/m2 and reasonably accurate colours. It’s bested by the Toshiba Chromebook 2’s budget-baffling Full HD screen, but it’s as good as it gets at this lower price. On a £400 laptop, we might complain about crushed blacks, and the contrast is nothing to write home about, but we’re prepared to cut this sub-£180 laptop some slack.

There’s Dolby DTS branding on the HP’s speakers, but we were a little disappointed with audio quality. While there’s a bit more low-range power and depth of tone than with many small laptops, it’s still tinny and heavy on the mid-range, with a tendency to distort if you push up the volume.The Stream 11 fares surprisingly well on the ergonomic front. The touchpad is 96mm wide with integral buttons, and while it feels a bit slow and stodgy to react at its default settings, move the pointer speed up a notch and it works perfectly well. We particularly like its silky smooth surface. The keyboard is better still. Nicely-spaced, with good-sized flat Scrabble-tile keys, it’s crisper and easier to work with than the keyboards on most rivals, and there isn’t much bounce in the base as you type, either. The price might be low, but HP hasn’t cut corners on connectivity. With one USB 2 and one USB 3 ports, plus an HDMI output, a headphone socket and a full-sized SD card slot, the Stream 11 comes as well equipped as most Ultrabooks – something that can’t be said about the similarly priced EeeBook.http://www.dearbattery.co.uk/acer.html
