Luanti (formerly known as Minetest, which is now the default game in the engine) is a community-driven, free and open-source voxel game engine, available on various platforms. Originally, Minetest was a voxel game created in October 2010 by Perttu Ahola to explore the mechanics of Minecraft. Over time, Luanti evolved from the original Minetest game into a general game engine as developers integrated new features.

I remember seeing a video of a blind woman using them, in combination with some earbuds, so she could get her surroundings described to her, as well as have objects she picked up described. But you’re right, glasses with discreet cameras on them, aren’t necessary for a situation like that - Something more overt would be fine for that use case.

Perhaps it’s Manam? Their island has a volcano, but they use a land-sea axis for directions:

Manam, like most Oceanic languages, primarily uses an absolute reference directional system, even on a local scale, (as opposed to many European languages which primarily use relative reference systems). This system is oriented on a land-sea axis. However, Manam’s system is unique because it has taken on a circular nature, becoming intrinsically linked to the geography of the island which is almost perfectly circular. Below are the directional terms associated in Manam:

llau ‘toward the sea’

Auta ‘toward the land’

Ata ‘to one’s right when one is facing the sea’

Awa ‘to one’s left when one is facing the sea’

The Wikipedia article doesn’t specifically phrase it as “towards/away from the volcano” , but Reddit posts linking to the Wikipedia article phrase it like that.
