Auto-tagging of Media using Local Bluetooth Information

This project explores the use of Bluetooth proximity information to automatically tag and share media captured during events. It aims to solve the challenge of keeping track of and sharing photos taken by multiple people. The system architecture involves an Android application that scans for Bluetooth devices, tags photos on capture, saves data locally, uploads to a web server, and shares URLs with participants via Bluetooth. The system was evaluated using two Android devices, demonstrating successful photo uploads and URL sharing via Bluetooth.

  1. Auto-tagging of Media using Local Bluetooth Information Emmanouil Alimpertis, Shonali Balakrishna

  2. Motivation & Related Work • Photos volume has been exploded due to use of smartphones. Difficult for users to keep track of media generated of them. • Challenges: Photos are taken by many people at different events, making sharing difficult. • Necessity: a platform that allows immediate tagging and sharing of media, based on proximity information. • There is no widely known App for auto-tagging media during events. Bluetooth (BT) proximity is considered for several applications; however, no work exists for auto-tagging of media to help users keep track of and share photos. • Related project: A. Pullabhatla & H. Gomes, “Proximity Data Gathering for Android Through Bluetooth”, CSE 237B, UC San Diego, Fall 2009.

  3. System Architecture • Android Application: i) Scans for BT Proximity Devices ii) Tags photo on capture iii) Saves data locally in ORMLite DB. iv) Uploads to Web Server using REST v) Share URL with Participants with BT. • Bluetooth Android APIs were used for proximity discovery of participants and for media URL sharing. • ORMLite was used as the relational mapper to persist objects to database to store the schema. • REST API was used to upload photo to a HTTP web server running PHP. Server responds with a public URL

  4. Evaluation & Use Cases • Application was evaluated using two Android devices, to send upload URL’s of generated media. • Basic Use Case: • i) Use Bluetooth to detect proximity devices (i.e. your friends) • ii) Create an event with location and duration. • iii) On creation of media, associate media with an event, upload to server and generate a URL • iv) Using Bluetooth, scan for friends and send a request for a tag. • iii) After acceptance, communicate media tag information and shares the URL with the participants.

  5. Results: Upload Photo

  6. Results: Use BT to share URL
