Looking Back on 2025 with a Focus on Yori Hiroi Frontend

2024 was the year I bought Vision Pro, and also the year I launched this site, Yori Hiroi Frontend. Then came 2025. As I wrote in my New Year's resolution, it became a year of pursuing Apple's visionOS ecosystem. Last year's retrospective and resolution are below.

At the end of last year, I wrote something like this.

> I am thinking of writing next year's resolution after the year begins, but next year will probably be less about challenging myself with new things and more about working harder on what I am already doing and producing results. This year, I feel like I challenged myself with a few too many new things.

Apparently, for 2025 I intended not to do too many new things, but to compete along an extension of the things I had been working on in 2024.

I did try a few new things, but in the end I think the year turned out that way.

First, the events I attended. I went to various events, but the ones I wrote about as articles are below. I attended XR Kaigi 2025 as press, so I feel I was able to look around more thoroughly than in other years. I also attended several events related to visionOS.

At the CSS Nite 20th anniversary event, I was also able to reunite with people I had not seen in a long time. After this event, I felt that the period when I was working only on the web had come to an end inside me. Of course I will continue doing web-related work, but it no longer feels like I will work while looking only at that area.

On the event side, the revival after three years of the Web Design Trends Osaka Edition was also something I did not expect. Speaking in a Web Design Trends session after a long time made me nervous, and I was grateful to be warmly welcomed by everyone in Osaka.

Speaking of presentations, I bought Even G1 from Even Realities and explored whether I could use it for work. By displaying cue cards on Even G1 during talks, I was able to create a state where text information appears in front of my eyes even though the glasses look like ordinary eyewear. In other words, it is a prompter that only I can see.

I developed a mechanism that displays information on Even G1 through Web Bluetooth from Marp, a web-based slide tool. I used it in practice and also exhibited the demo.

Of course, I also explored many visionOS-related things. The most memorable were helping run VisionDevCamp Tokyo 2025, a three-day visionOS-only hackathon, exploring VR180 video, and releasing Seiro MCP.

I am convinced that Seiro MCP will play an important role in my future visionOS development. But beyond that, it also became a meaningful product as my way of approaching AI, after I had spent the past two years leaning too heavily toward XR.

In fact, before I started building Seiro MCP, my understanding of MCP servers and AI agents was shallow. I thought I understood them reasonably well, but I realized that I actually did not understand them that much. Now, through the development of Seiro MCP, I have become able to catch up on AI as well. Seiro MCP is also built in Rust, a technology I want to pursue further, so getting it released was a good move.

In the end, I think 2025 was a year when I kept visionOS at the center of my exploration while continuing to value web design and frontend work, and still managed to challenge myself in new areas.
