A 'life logging' camera designed to be worn constantly and take photographs automatically has hit its first Kickstarter funding target within five hours.
Memoto is designed to be the world's smallest wearable camera.
The aim, its makers say, is "to create a continuous life log for the user" by producing a searchable and shareable "photographic memory".
It is similar in some respects to the UK-made Autographer camera, which is set to go on sale in the UK soon.
Both raise questions of privacy for those who would be unwittingly captured on camera by their wearers - though the makers of both devices say that those concerns are overplayed.
The team behind Memoto said they "wanted to find a way to relive more of our lives in the future - and enjoy the present as it happens".
Kickstarter users agreed, and with 38 days of its funding round to go have already sent the company $57,284 in early support.
One generous donor pledged $5,000 in return for a camera as well as a trip to Stockholm to talk about future gadgets.
The camera will take five megapixel images every 30 seconds. It will use a custom smartphone app to download and organise photos, and will allow two full days of pictures on its included memory.
By contrast the Autographer camera uses a variety of sensors including temperature, light and movement to judge when to take a new photograph.
