Project Description:
We hope to prototype and examine the use of a multimedia blogging system that leverages a marriage of existing technologies to to enable users to share information relating to place. The project consists of two components: 1. Upload: A mobile application that automatically attaches geo-spatial & temporal information to captured multimedia (using photos as a starting point) and uploads it to a web-based blogging system whenever the phone enters an area with network connectivity. 2. Viewing: A blog-viewer can view the uploaded multimedia in the traditional chronological format or in a new geo-spatial format. For example, a blogger riding their bike across the US would be able to have friends and family "follow along" (via photos/audio/video/etc) by selecting numbered blog entries from a large map.
Future implementation could include a "viewing" interface for mobile devices that allows users to access previously uploaded information linked to the location in which they are present. For instance users can upload audio comments that are geo-spatially tagged and are made available to other users when their device enters the same location.

Target Users:
Broadly speaking, target users are all cell phone users, particularly those with picture and voice recording capabilities. Specific to this study will be users of devices that can record and send images and whose devices offer the capability to interface with geo-spatial data devices (eg. gps devices via bluetooth). Future use of the proposed system may be centered among social networks (friends, family, co-workers), academics (field research teams) and tourists.

UI Capabilities:
There are two UI's: 1. Upload UI: Should allow users to simply and efficiently upload data (images, audio, text) from their mobile device while the device automatically attaches metadata (temporal and geo-spatial information). 2. Viewing UI: Should allow users to view gathered data (in this case, images) semi-synchronously and should allow them to manipulate the arrangement of photos to correspond with either the geospatial location of their capture or with related temporal data.

Evaluation Methods:
We plan to evaluate via user testing with various iterations of a prototype system. We may also perform comparative tests with similar interfaces that currently exist such as current mobile devices with e-mail and photo uploading capabilities and current photo blogging sites such as Flickr. Comparisons and/or evaluation criteria will relate to usability and efficiency factors observed during user upload and viewing trials.

Potential Research Value:
By integrating several existing technologies with an eye toward reducing the latency between capture and upload and toward organizing field-gathered user-data with reference to geospatial location, we expect to unearth a plethora of possibilities for future use. Further testing in a variety of contexts can advance this discovery of possible use-contexts. These contexts may include: integration with field research projects such as Butterfly Net, use in classrooms to share personal cultural artifacts with students in other countries, the inception of a collective database of local information and opinion for tourists and recent transplants to a region.
