A spatial interface earns consideration through the task it helps someone understand.
Name the work before designing the world
Give position a meaning
Keep actions clear across views
Compare the experience, including its effort
What the note asks us to consider.
A note on evaluating spatial interfaces against a clear task, its information and the effort involved.
A task belongs to a project. A decision depends on information. An action can affect work beyond the place it begins. These relationships suggest possibilities for spatial interfaces, but they do not establish that space will make the work easier.
If two objects appear beside each other, a person may infer a relationship. Placement should communicate something useful about the work rather than add visual activity.
Changing the interface should not change the meaning of an action. People need to understand what is selected, what will happen and how to return to the wider task.
A useful study would compare a defined task in a spatial concept with a clear conventional interface. It should examine understanding, completion and the effort each approach requires.
