Hackathon

2026.06.26

At the core of XR VisionDevCamp is the hackathon. Attendees group into teams, build a project on-site, and demo it on the closing day. Projects are placed into categories; teams win awards and prizes for their entries. Most participants form teams after arriving with people they have never met before — established teams may also attend together.

Quick reference — Fri 26 June, 5pm open / Sun 28 June, 12:00 JST entry deadline / 13:00 judging / 16:00 ceremony.

Core Values

At all DevCamp events, recognition is given to attendees demonstrating these values:

  • Contribution — assisting the commons, offering value, being useful.
  • Sharing — offering help, sharing code or expertise, assisting in testing or debugging.
  • Openness — asking good questions, answering them, being open to people and ideas, making source code available.
  • “Can-Do” attitude.

Raffle Tickets

“Tickets” are distributed when participants demonstrate these values. Teams presenting during Hackathon Demos receive a ticket. Tickets are used for raffle drawings for general prizes — the more tickets you have, the more likely you’ll receive a general prize.

Structure

Team Forming

Friday evening and Saturday morning feature open-mic times for announcements about team formation, seeking talent, or joining teams. Staff actively assist participants struggling to make connections. Teams may also form prior to the event via Discord or our contact form.

Team Focus Time

Teams assemble and work on projects for the majority of the event. Most time is unstructured for preparation toward Sunday’s Hackathon Demos.

Entry Deadline

Teams wishing to demo and compete must submit an entry form no later than 12:00 JST on Sunday 28 June 2026. A submission link will be provided during the event. If submissions exceed available demo time, submissions that offer source code under an open-source license will be given first priority, then submissions the moderators think are particularly strong.

Hackathon Demos

Demos take place on Sunday afternoon at the CIC Fukuoka / Fukuoka One Building main venue. Each demo is approximately 3 minutes. Multiple displays enable rapid transitions between presentations. Where possible, please use the device’s standard screen-mirroring feature (e.g. Apple Vision Pro mirroring) to demonstrate spatial features.

Judging

After demos conclude, event moderators consult on winning entries. Winners are selected at the sole discretion of the event staff, except for special co-sponsored award categories, which include sponsor representatives in the selection process.

Ceremony — Special Awards

Valuable prizes from sponsors are awarded in special-award categories. Each special-award sponsor will have the opportunity to say a few words and personally present the award to the winner if they are present. Event staff may also award special recognition to non-demoing participants who exemplified sharing, participation, and a “can-do” attitude.

Ceremony — Sponsored Awards

Sponsored awards are distributed for sponsored award categories.

Ceremony — General Awards

Desirable general prizes are awarded by random draw to hackathon participants. Remaining prizes go to those holding the most tickets.

Clean-Up & Closing Party

Participants are invited to help reset the venue. Source code and demo recordings will be released publicly that evening. A closing party (taco truck, outdoors) follows.

AI Use Policy

AI tools are allowed — coding assistants, image/asset generators, LLM-based agents, on-device models, and similar are all welcome. Most modern XR projects will benefit from them.

Disclosure (required)

At submission time, teams must disclose:

  • What AI tools or services were used (e.g. specific model, IDE assistant, generation service).
  • Whether any of them were paid services — and if so, which.
  • Team’s experience level with AI — first-time user, regular user, or expert.
  • Whether AI is required at runtime to run any part of the demo (e.g. live LLM call during the demo) — judges need to know in advance for venue networking.

Judging

Judges will not weight for or against AI use in itself.

However, completeness is a judging factor, and AI-augmented projects are reasonably expected to achieve a higher grade of completeness in the same time-budget. Where two entries are otherwise comparable in concept and execution, the more complete one will likely score better — regardless of how it got there.

To keep the playing field level, judges may choose to split a category award between AI-assisted and non-AI-assisted entries (e.g. Best XR (AI) and Best XR (Hand-Built)) when the field warrants.

Some sponsors may offer AI credits as prizes; those sponsors may require AI use as a condition for their specific prize category. Such requirements will be stated in the category description before submission.

Eligibility

General Prizes

Everyone is eligible for general prizes by earning a ticket through participation, demoing, or demonstrating the core values.

Special Awards

To be eligible for a special award, an entry must satisfy all of the following:

  • The application must not currently be publicly distributed without source available (e.g. on a closed app store) — or, if so, source code must be available on a public repository.
  • The team must register for the hackathon by the entry deadline.
  • The team must demonstrate the application during demos. If too many submissions exist, moderators may have to make a judgment call regarding which entries fit in the demo block.
  • Event staff are not eligible for special awards.

Special Award Criteria

  • Categories may have additional requirements set by special-award sponsors.
  • Applications in most categories are judged on function, fun, and aesthetic appeal.
  • Simplicity and elegance are valued.
  • Special recognition is given to applications developed during XR VisionDevCamp itself. Pre-existing applications and data are acceptable provided the judges are informed.
  • Priority is given to applications offering source code under an open-source license — though this is not a strict requirement to win.
  • Applications do not have to be “finished” to win — we’d rather see what your application can do well than something polished but generic.

Award Categories & Prizes

The full prize-category list for 2026 — Best Unity, Best AVP, Best Android XR, Best XR, Best Team, Best Solo, Best AI, Best Artistic, Best Concept, Best System Design, plus categorical awards (Game · Utility · Health & Fitness · EDU/Training · Storytelling) — is on the Schedule page.

Sponsorship of devices and prizes for the 2026 event is open.

Code of Conduct

XR VisionDevCamp follows a community-first code of conduct. Be welcoming, be inclusive, and treat fellow participants with respect. The full conduct policy will be linked here closer to the event.
