Abstract: A camera system including an integrated coupling system configured to releasable couple the camera system with a user head accessory such as a pair of glasses, a hat, a headband, an item of jewelry, etc. The camera module may have an outer dimension smaller than three cubic inches and may further include a data coupler, battery, lens, image sensor, circuit board, and microphone. The camera module may transmit and receive data from the portable computer device including video data and on/off recording, respectively. A magnetic coupling system configured to selectively releasably couple the camera module directly with the user head accessory including magnet(s) disposed within each of the camera module and the user head accessory.

Abstract: A method of facilitating bartering includes receiving a first input from a first user, a second input from a second user, and entering the inputs into a database to create a listing for each user. The first input includes a first item for trade and a criteria for trade. The second input includes a second item and a category of items or subcategory of items to be obtained that satisfies the criteria for trade. The method further includes searching and filtering items within the database to identify a match, generating an electronic message including information related to the match and sending the electronic message to at least one of the first user and the second user, and enabling the first and second users to respond to the electronic message and share contact information.
