This Pokéball wearable could let you catch a Magikarp in the Thames

Remember the very first time you picked out your own
Charmander and stepped out through Professor Oak’s lab
door? We do. We were assaulted by some rats in the long
grass near his house shortly after. It was a great day.
Thanks to Pokémon Go - a mobile title revealed by the
Pokémon Company - those memories will become a sort-of
reality.
Developed by Niantic Labs (the folks behind AR game
Ingress) and Nintendo, Pokémon Go brings virtual
Pokémon into the very streets, parks and other public
places you walk through on a daily basis.
Players will be able to catch and train their own Pokémon,
in addition to battling other trainers in real-world settings,
presumably being rewarded with some sort of Pokémon
street cred in the process.
Unlike Ingress, which requires the app to be open, the
optional Pokémon Go Plus wearable can be used to alert
you of wild Pokémon and opponents in the area with a
flash and a buzz, without you having to have the app open
on your phone.
Nintendo designed the little device to encourage people to
stop staring at their screens so much, and don’t worry, you
don’t have to actually wear it on your wrist for it to work.
Very little has been shown off at the moment beyond the
wearable and a few screenshots of Pikachu and Charizard
standing in a virtual field, but colour our inner child very
excited.
