May I claim something somewhere between those two options? No, it is not backed up with controlled experiments with statistical analysis of the significance of results. But yes, it is backed up by corroborating evidence. At least I interpret the great popularity of on-mouse-over transient displays as evidence of greater usabilty for local variations in the display against a stable ground, as compared with a total context swap which fails to carry along any particulars from the context where the real problem is. On the other hand, it is often not appreciated why people with visual impairments often prefer a flattened static or "offline" presentation of large bodies of material. My interpretation is that this is because the navigation grid is reliable, and can be operated on from memory, in this sort of a space. So there is evidence in both directions. For a home-grown example, consider how well The WAVE was received. This give feedback inline rather than offline. So I consider what I said a strong hypothesis with some evidence to support it, and eagerly await more information that would confirm, deny or adjust it. Are you aware of any good objective studies that would be within spitting distance of extrapolation to this scenario?
