Eitarosoft has developed a 3D world based on the Google Android platform for mobile phones and advertises its claim that it can host 400 concurrent users within one environment, a clear knock on Second Life’s 40-or-so avatar limit per sim.

Says Eitarosoft:

eitarosoft, inc. today announced that they have successfully developed a 3D virtual world service on Google’s platform “Android”. The conventional 3D virtual world service required the use of a very high-specific PC, but Android-mounted mobile devices will enable users to enjoy the 3D virtual world service with commonly available PCs because of the mobility and accessibility.

Their video demos the world:

Eitarosoft’s business model seems to be primarily advertising-based. By allowing embedded Web pages within the 3D world “sponsor companies of this service can provide their promotional information. Therefore, companies need not prepare 3D graphics images for the purpose, thus enabling them to save cost on advertisements. In addition, sponsors can release new promotional information at the right time they like to.”

What’s unclear is whether the service will be able to work in reverse of the SL challenge, which works fine on a PC but only has a few options for mobile access. Whether the Google-based platform will also work on a PC isn’t stated.

Their Web content is either translated or poorly edited, and I find the “commonly available PCs” comment ambiguous since the world itself is shown on a phone – maybe that’s what they mean, although clearly they’re no strangers to PC-based (usually Java) virtual worlds with cute little Japanese-style cartoon avatars.
