MixMeet: Live searching and browsing

on

Knowledge work is changing fast. Recent trends in increased teleconferencing bandwidth, the ubiquitous integration of “pads and tabs” into workaday life, and new expectations of workplace flexibility have precipitated an explosion of applications designed to help people collaborate from different places, times, and situations.

Over the last several months the MixMeet team observed and interviewed members of many different work teams in small-to-medium sized businesses that rely on remote collaboration technologies. In work we will present at ACM CSCW 2016, we found that despite the widespread adoption of frameworks designed to integrate information from a medley of devices and apps (such as Slack), employees utilize a surprisingly diverse but unintegrated set of tools to collaborate and get work done. People will hold meetings in one app while relying on another to share documents, or share some content live during a meeting while using other tools to put together multimedia documents to share later. In our CSCW paper, we highlight many reasons for this increasing diversification of work practice. But one issue that stands out is that videoconferencing tools tend not to support archiving and retrieving disparate information. Furthermore, tools that do offer archiving do not provide mechanisms for highlighting and finding the most important information.

In work we will present later this fall at ACM MM 2015 and ACM DocEng 2015, we describe new MixMeet features that address some of these concerns so that users can browse and search the contents of live meetings to retrieve rapidly previously shared content. These new features take advantage of MixMeet’s live processing pipeline to determine actions users take inside live document streams. In particular, the system monitors text and cursor motion in order to detect text edits, selections, and mouse gestures. MixMeet applies these extra signals to user searches to improve the quality of retrieved results and allow users to quickly filter a large archive of recorded meeting data to find relevant information.

In our ACM MM paper (and toward the end of the above video) we also describe how MixMeet supports table-top videoconferencing devices, such as Kubi. In current work, we are developing multiple tools to extend our support to other devices and meeting situations. Publications describing these new efforts are in the pipeline: stay tuned.
