And what is delight? For me, delight is born from a tool’s intuitiveness. Things just working without much thought or fiddling. Delight is a simple menu system you almost never have to use. Delight is a well-balanced weight on the shoulder, in the hand. Delight is the just-right tension on the aperture ring between stops. Delight is a single battery lasting all day. Delight is being able to knock out a 10,000 iso image and know it'll be usable. Delight is extracting gorgeous details from the cloak of shadows. Delight is firing off a number of shots without having to wait for the buffer to catch up. Delight is constraints, joyfully embraced.
There are many visual design guidelines but the basic principle might be summarized as the Visual Information Seeking Mantra:
Overview first, zoom and filter, then details-on-demand
Overview first, zoom and filter, then details-on-demand
Overview first, zoom and filter, then details-on-demand
Overview first, zoom and filter, then details-on-demand
Overview first, zoom and filter, then details-on-demand
Overview first, zoom and filter, then details-on-demand
Overview first, zoom and filter, then details-on-demand
Overview first, zoom and filter, then details-on-demand
Overview first, zoom and filter, then details-on-demand
Overview first, zoom and filter, then details-on-demand
Each line represents one project in which I found myself rediscovering this principle and therefore wrote it down it as a reminder. It proved to be only a starting point in trying to characterize the multiple information visualization innovations occurring at university, government, and industry research labs.
