How Wearable Technology Can Save Your Presentation

There isn’t much in life that’s more nerve wracking than speaking in front of a large audience. However, researchers from the University of Rochester believe they’ve come up with something that may be able to help.

They have developed an application for smart glasses that will give you a range of feedback on your performance in real time.

The service, called Rhema, which is freely available via the team’s website, was presented at a recent conference in Atlanta.

The service will provide speakers with a recording of their speech which will be analyzed in real time for things such as volume and speech rate. This data is then presented to the speaker live to hopefully allow them to adjust either their cadence or volume (or ignore the advice altogether).

The authors have analyzed, and indeed tested out, the glasses themselves while giving lectures over the last year.

"My wife always tells me that I end up speaking too softly," they say. "Rhema reminded me to keep my volume up. It was a good experience."

The hope is that by being more aware of these things, and getting objective feedback, it will aid our presentations even when not wearing the glasses.

Providing real time feedback

Of course, the provision of real-time feedback presents a number of challenges.

"One challenge is to keep the speakers informed about their speaking performance without distracting them from their speech," they reveal. "A significant enough distraction can introduce unnatural behaviors, such as stuttering or awkward pausing. Secondly, the head mounted display is positioned near the eye, which might cause inadvertent attention shifts."

In a bid to overcome this, they thoroughly tested the glasses on a group of speakers, testing out a range of feedback mechanisms as they went.  For instance, they tried using a traffic light like system of lights, written feedback, data in graph form, and even more unusual methods such as providing a continuous and slowly changing display, or providing sparse feedback once or twice during a talk.

After testing, it emerged that the most effective form was to provide a written prompt every 20 seconds or so. So the speaker might receive a prompt to speak louder, or slow their cadence down, or even nothing at all if they’re already on track.

In addition to testing the system on speakers themselves, they also wanted to gain some feedback from the audience too.

"We wanted to check if the speaker looking at the feedback appearing on the glasses would be distracting to the audience," they say. "We also wanted the audience to rate if the person appeared spontaneous, paused too much, used too many filler words and maintained good eye contact under the three conditions: word feedback, continuous feedback, and no feedback."

Interestingly, it emerged that there wasn’t really any difference at all, whether on things such as eye contact, being distracted, unnatural use of words or appearing stiff on stage.

To further test the system, the researchers want to work closely with Toastmasters International to put it through a rigorous examination from people steeped in public speaking.
