Fully Charged: Toyota’s mad mood ring car, the app that fixes your posture and Call of Duty: Ghosts PS4/PS3 comparison

Channel your inner Boudica with Toyota’s bizarre chariot-slash-Tamagotchi concept

The Toyota FV2 is likely to be one of the most interesting concept vehicles on show at the upcoming Tokyo Motor Show. It’s a little like a Segway (except that it has four wheels and not two) and it’s a little like a virtual pet (except that it’s a sort of car).

The FV2 doesn’t have a steering wheel, so in a Segway-esque fashion you shift your body weight to control its speed and direction. Even better, it monitors your voice and facial expressions to determine your mood, then changes the colour of the exterior to reflect it. Brilliant – now everyone will know when you’re suffering from road rage and on the point of blowing your stack. There’s an augmented reality windscreen too, natch.

Toyota feels that this ability to monitor the driver’s disposition will see FV2 users bonding with their machines, much like a rider bonds with a horse. Neigh bother.

LUMOback: an activity tracker that also improves your posture

LUMOback is a gadget inspired, we’d like to think, by your old primary school teacher. How so? Well, it tells you, much like he or she did, to STOP SLOUCHING and SIT UP STRAIGHT.

A wearable sensor that pairs with a smartphone app, it monitors your posture and vibrates when it’s poor. It also tracks your movements and activity much like any other wearable sensor. The device is on sale now from the Apple Store, priced at £130, and the app is compatible with most iOS devices.

App lets you “Knock to unlock” your Mac

A new app allows you to wirelessly unlock a Mac computer simply by knocking on your iPhone screen: no password-typing required. The aptly-named Knock works with most post-2011 Macs and any iPhone model after the 4S, and because it uses Bluetooth there’s no danger of you mistakenly unlocking your iMac from the other side of the world. You can download it for iOS here (it’s £2.49) and for Mac here.

Watch Call of Duty: Ghosts side-by-side on PS4 and PS3

Want to see the differences between the PlayStation 4 and PlayStation 3 editions of Call of Duty: Ghosts? Well, this comparison video might help you decide if it’s worth waiting for the former; it runs the first 15 minutes of the game side-by-side. To our eyes, there’s not a huge difference, although the PS4 seems crisper and punchier – as you’d imagine from a brand new machine competing against something that’s been around since 2006.
