An Australian computer scientist has developed the world's first shoe phone, and has even published detailed step-by-step instructions online.
According to a report in the Sydney Morning Herald, Paul Gardner-Stephen, the inventor, insists there are practical applications of this phone, including, helping the elderly.
Gardner-Stephen, a post-doctoral fellow in bioinformatics at Adelaide's Flinders University, made the gadget as a prop for a church camp drama presentation that had a "Get Smart" theme.
But after scouring the web and discovering that no one had created a shoe phone that was fully functional as a phone and could also be worn as a shoe, Gardner-Stephen set himself the challenge.
The first iteration, made in October last year, was simply a Bluetooth headset embedded in the sole of a shoe. The wearer still had to carry a mobile phone in his or her pocket.
Then, in December, Gardner-Stephen refined his design and, with the help of a cobbler friend, embedded a Motorola V620 in one shoe and a Bluetooth headset in the other.
The cobbler crafted hollow heels with a hatch that could fit the phone and headset.
"It's surprising, your first thought is it's completely impractical, but it's actually not that bad. The phone rings, you slip off the shoe, you open the heel and press the button and you're talking in around the same time it would take to fumble in a bag and pull the phone out," said Gardner-Stephen.
