Google introduced a new presentation feature to Google Slides for Android. The latest update to the app enables you to quickly present your slides through a Google Hangout. I finally had a chance to test it this morning and it worked fairly well although not nearly as well as using full webinar service like GoToTraining.
To remotely present your slides through Google Slides for Android simply open your slides and choose the "present" option. After choosing "present" you will be asked to either initiate a new Google Hangout or join one that you have previously scheduled in your Google account. I tried it both ways and found it much easier to just initiate a new Hangout.
Applications for Education
Students who are working with partners to develop a presentation and are Android tablets, might appreciate the new option to quickly share slides remotely.
