Idea Selection

Geotagging photos on Flickr using Anoto-paper map.

Members of the digital generation wish to share their lives with the world online. This is evidenced in the rising popularity of moblogging (mobile blogging) and Flickr's recent addition of their geotagging feature. Our application has social value in making it easier for friends to communicate their experiences with each other and it's something that people can use every day.

[edit]

Target User Group

We are targeting travelers who wish to share their experiences on the fly (for example, those who would like to build a travel log). Specifically we are targeting mobile bloggers (mobloggers) who would like to geotag their photos for sharing on Flickr. Our users are internet-savvy amateur content creators.

Problem Description

Cameras are not location-aware. We wish to provide this information as the photos are being taken so that they can later be viewed in context of their location, along with other metadata captured in real-time such as tags.

[edit]

Problem Context

Joe has been out hiking in the Grand Canyon all day and has been taking photos of various landmarks. He wants to see a map of his travels with his photos placed in the right spots, and share it with his friends.

Nancy is in SF and wants to share her bar-hopping experiences with her friends in real-time.

[edit]

Why Anoto?

The Anoto is advantageous because it can be used in field conditions, immediately upon photo capture so that the location will not be forgotten. If a very local map is used, resolution will be higher than is possible with GPS. Additional real-time metadata (e.g. tags, names of people) could be provided alongside the location data, giving it another advantage over existing GPS units.

Solution Sketch

Before the trip, the user prints out a map of their location. The map also allows the user to perform various actions with their photos (e.g. tagging, posting, privatizing, etc.). As the user takes a photo, they simultaneously mark their location on the map along with any desired actions and tags for the photo. Later, the pen data is correlated with the photos using timestamps and the desired actions are applied to the photos. If the user has a cameraphone, this can all happen in realtime; if using a traditional digital camera; this happens upon downloading photo and pen information to the user's computer.
