When I got my Nokia E71 smartphone, I also bought a hands-free device for it: the Sygnet Bluetooth Handsfree Carkit model BTS600. This actually works quite well – it wirelessly identifies the phone on my belt when I get in the car, and until I leave the car all calls are routed to this device. Throw in voice recognition based dialing, and it’s convenient indeed.
Still, the controls of this elegant space age device – it really looks like a miniature flying saucer, doesn’t it? – embody some basic human engineering errors, ones that are all too common in other products; we can call them control cloaking and control overloading.
By control cloaking I mean making controls that are all but invisible and indistinguishable from each other. The BTS600 has only four controls: a power switch, and the three marked with +, – and a handset symbol. The user needs to identify the last three rapidly, at a glance, while driving a motor vehicle. So what would you do to make this easy?
I know what I would do: I would design large, obvious buttons, each differing markedly from the others in color (for daytime use) and in shape (for night time driving). Something like the three skyscrapers in the Azrieli Center in Tel Aviv – one round, one triangular and one square, and all impossible to miss…
Not so the good engineers at Sygnet. They made the three buttons flat, and blended them into the device’s surface so elegantly that you can barely make them out – with tiny labels that are hard to read even when parked. And the device’s perfect circular symmetry makes it impossible to locate the buttons by their positions relative to its edges.
And then there’s the matter of indicator lights. The device has two lamps: blue and red. You’d expect these to be visible from all angles; which would be the case if they protruded outside the casing. But instead they are sunk deep inside, under the clear plastic ring around the speaker grille. Again, very elegant – but quite invisible unless you look straight in.

So, what magic do we make there? Semantinet, as the name hints, applies leading edge semantic search technology to enable a whole new manner of experiencing the web. Its product, headup, is a Firefox add-on that identifies on pages you browse names of entities like people, places, events, books, musical artists, videos, and more; and it shows you on demand a small window with additional information on any of these.
“Truth in advertising” sometimes seems an oxymoron, and the cosmetics industry is hardly where you’d expect to find much of it. So hats off to Neutrogena’s Norwegian Formula hand cream, whose statement on the tube that it “instantly relieves dry or chapped hands – just a dab needed” is absolutely correct. They claim it was devised from the experience of Nordic fishermen with the effect of fish oils; be that as it may, I can attest that this formula really can handle chapped skin that would laugh at your usual hand lotion.
crew them.
Take the image at right, the list you have to go through to select a country for a new contact in Outlook and other applications: it opens on a list of ten countries, of which one – Argentina – may be even remotely likely to be inhabited by business contacts of yours. You can scroll down, of course… and in the next ten you find even greater concentrations of business partners, like the entry for the
