Google is testing Google Drive presentation support for Chromecast

Google (s GOOG) is apparently testing the ability to cast presentations directly from Google Drive to Chromecast. The new feature, first discovered by a German user, allows users to select Chromecast as an external playback device for presentations, allowing them to still read their presentation notes on their computer while their presentation is playing on a TV screen or projector with a Chromecast adapter attached.

Google Drive to Chromecast

Previously, Chromecast users could only cast Google Drive presentations to the TV by mirroring an entire browser tab, making it impossible to view their notes while the presentation was running.

The new “present on another device” feature doesn’t seem to be available to everyone yet – I was not able to access it on either my desktop Chrome browser or the Google Drive app running on my Nexus 7. This suggests that Google may still be testing the functionality, and could roll it out to additional users at some later point.

Google has been fairly slow to add features to Chromecast. The streaming stick was released in late July with the promise of additional apps coming soon after, but since then, only Hulu Plus has been made available to Chromecast users. However, Google has been quietly testing additional functionality, including the ability to cast YouTube videos embedded on third-party websites.

I’ve asked a Google spokesperson about the new feature, but have yet to hear back.
