Did you ever wonder why they wave their mobiles in the clubs?Feature of the week
If you have been in a club lately you may have noticed strange behaviour in groups of friends. Naturally you wondered why those girls were waving their mobiles or boys doing Haka-style high-five moves with their handsets in their hands.
It’s not the revival of a tribal tradition, the newest mobile phones feature accelerometers that, combined with the use of the already established Bluetooth technology, let you communicate with hand gestures.
Originally these accelerometers were implemented to accurately establish the orientation of the phone – think about when you rotate it take a picture and it switches to landscape format – but shortly afterwards software developers realised that there could make more innovative and fun uses of it. A few months later loads of new apps and games entered the market – it can also help detect bipolar disorder.
We all already knew Bluetooth – for better or worse – and its pairing functions that can allow the sending of messages and exchange of pictures and data without having to use your monthly allowance. And usually a password is required to pair devices, preventing strangers from accessing our information (Bluejacking) liked used to happen in the past. That’s why you saw that Haka-style rite.
Instead of using a password, friends would establish a number of shakes and gyrations of the phone – amusing or stylish as you wish – and each movement of the device is translated into a code through the accelerometer technology. It can be simple but for it to be fun and exclusive you can go for a very complex pattern. The movement-generated code is then used by the devices to connect and share images and videos via Bluetooth. The number of possibilities are endless, a simple Google search will show you how to book a two-week holiday with a tap or how to deposit using a mobile phone. You just need to make sure you own one of the latest models.
