The basic problem here is that a given screen contains a massive amount of information, and most of it is meaningless. There might be hundreds of tiles, most of which is just random grass and trees, yet any detail could prove important. While it's theoretically possible for a text interface to tell you exactly where everything is, it would be tedious to do so even once, much less every time you took a step. If you ask me, your best bet is to have a sort of limited bot that asks you what to do, enters the commands for you, and then gives you the result. For example, a text interface for adventure mode, using such a bot, might go like this:
"You are standing in a field, surrounded by plump helmets. There is a small wooden house to your north and another to your northwest, a hill to your east, and a vulture above you. The sun is high in the sky."
attack vulture
"You cannot reach the vulture"
throw dagger at vulture
"The spinning dagger strikes the vulture in the head, and the severed part flies off in an arc! The vulture has been struck down. The vulture corpse falls a moderate distance to the ground."
pick up dagger
"You pick up your dagger"
butcher vulture corpse with dagger
"You butcher the vulture corpse. You see [insert long list of parts here]"
Pick up all vulture parts
"You pick up [same list of parts]"
Go to house
"Which house? There is a house to your north, and to your northwest."
Go to north house
And so on and so forth. Do you understand what I'm going for here? Just targeting the vulture with the dagger would have been a huge pain to do yourself, and it might not have been immediately evident that you couldn't do reach it for close combat. This way would be much cleaner, and wouldn't waste your time with specific information that isn't necessary. It would also be difficult to implement, although I can't say how difficult since I lack the skills to do it myself. One thing that this method has going for it is that the simple interface and style has appeal for those who aren't blind as well as those that are, so willing programmers might not be too hard to find. Assuming this is even possible.
