View & Share: A Collaborative Media Viewing and Sharing Framework using a Projector Phone.

The limited screen size and resolution of mobile phone screens makes it difficult to view media in a group setting. Co-present media sharing is currently not easily supported by mobile phones. Typically, media sharing is orientated around the media owner who has to perform several tasks to send a single photo per recipient. Moreover, group formation and collaboration to support media sharing is also not supported by mobile phones. Projector phones, mobile phones with integrated projectors, provide a new way to collaboratively view and share mobile media. We present View & Share, a collaborative mobile media viewing and sharing framework using such phones. Within the framework two roles are supported, the presenter of the media and the viewers of the media. The framework utilizes a viewer initiated interaction technique whereby the focus of sharing media is shifted from the media owner and performed by the media viewer(s). A presenter initiated interaction technique facilitates sharing to the entire group using an intuitive gesture. Using this technique the issue of viewing inappropriate or private content in public is solved by utilizing the personal mobile screen of each member within the group. The framework also supports the temporary sharing of the projected display
