The Even G1 and Marp demo exhibit at LODGE XR Talk Vol.30 has ended

The exhibition booth

At LODGE XR Talk Vol.30, held at LODGE on August 21, I exhibited a demo at a booth in the venue where Even G1 and Marp were connected with Web Bluetooth to display something like presenter notes in the air.

This relates to the smart glasses + Web Bluetooth work I have been doing recently. This time, Marp slides were displayed in Chrome on a MacBook Air, and when the page changed, the text displayed on Even G1 also changed.

I also created a popup display for the day, which I will write about somewhere else, and gave technical explanations to people who were interested. I am deeply grateful to the organizers for giving me this kind of opportunity. It is a wonderful event.

Although Web Bluetooth connection and text transmission were quite difficult, I tried to make editing Marp content very easy.

You can write comments inside pages of a Markdown file for Marp, and I made it so that when the slide page containing a comment is displayed, that comment appears on Even G1 as presenter notes. For example, writing the following in a Markdown file means it will not appear on the slide, but "Hello World!!" will be shown on the smart glasses as presenter notes.

<!-- Hello World!! -->

This may make it easy for Marp users to adopt. So I plan to use this mechanism in various lightning talks for a while and test it.

At the venue, I demonstrated Japanese display, bullet text with line breaks, displayable symbols, and long text. Having participants use it gave me various feedback.

  • Display images too
  • Display text faster
  • The connection flow is complicated

And so on. Some feedback seems like it can be addressed quickly, so I will keep researching. I plan to polish it a little more and eventually release it as OSS.

Thank you to everyone who participated.
