The company usually associated with building fast motorbikes and incredibly reliable cars has turned its attention to protecting smartphones from accidental damage. Called the Honda Smartphone Case N, the end result is a handset case that will deploy airbags if it senses the phone is falling — i.e. Honda claims that thanks to the accuracy of the in-built accelerometer, the airbags — all six of them — can be deployed in 0.2 seconds. And while Honda is clearly being less than completely serious with its latest innovation, as the accompanying video — created to publicize the safety systems in its N Wagon — attests, the problem it is addressing is a serious one.
