Calm Technology: designs which require only peripheral attention

"The most potentially interesting, challenging, and profound change implied by the ubiquitous computing era is a focus on calm. If computers are everywhere they better stay out of the way, and that means designing them so that the people being shared by the computers remain serene and in control. Calmness is a new challenge that UC brings to computing. When computers are used behind closed doors by experts, calmness is relevant to only a few. Computers for personal use have focused on the excitement of interaction. But when computers are all around, so that we want to compute while doing something else and have more time to be more fully human, we must radically rethink the goals, context and technology of the computer and all the other technology crowding into our lives. Calmness is a fundamental challenge for all technological design of the next fifty years. The rest of this paper opens a dialogue about the design of calm technology. ...

We use 'periphery' to name what we are attuned to without attending to explicitly. Ordinarily when driving our attention is centered on the road, the radio, our passenger, but not the noise of the engine. But an unusual noise is noticed immediately, showing that we were attuned to the noise in the periphery, and could come quickly to attend to it.

It should be clear that what we mean by the periphery is anything but on the fringe or unimportant. What is in the periphery at one moment may in the next moment come to be at the center of our attention and so be crucial. The same physical form may even have elements in both the center and periphery. The ink that communicates the central words of a text also peripherally clues us into the genre of the text though choice of font and layout.

A calm technology will move easily from the periphery of our attention, to the center, and back. This is fundamentally encalming, for two reasons.

First, by placing things in the periphery we are able to attune to many more things than we could if everything had to be at the center. Things in the periphery are attuned to by the large portion of our brains devoted to peripheral (sensory) processing. Thus the periphery is informing without overburdening.

Second, by recentering something formerly in the periphery we take control of it. Peripherally we may become aware that something is not quite right, as when awkward sentences leave a reader tired and discomforted without knowing why. By moving sentence construction from periphery to center we are empowered to act, either by finding better literature or accepting the source of the unease and continuing. Without centering the periphery might be a source of frantic following of fashion; with centering the periphery is a fundamental enabler of calm through increased awareness and power.

Not all technology need be calm. A calm videogame would get little use; the point is to be excited. But too much design focuses on the object itself and its surface features without regard for context. We must learn to design for the periphery so that we can most fully command technology without being dominated by it.

Our notion of technology in the periphery is related to the notion of affordances, due to Gibson and applied to technology by Gaver and Norman. An affordance is a relationship between an object in the world and the intentions, perceptions, and capabilities of a person. The side of a door that only pushes out affords this action by offering a flat pushplate. The idea of affordance, powerful as it is, tends to describe the surface of a design. For us the term 'affordance ' does not reach far enough into the periphery where a design must be attuned to but not attended to."

Limitations of the Decision Cycle Model of Interactive Interfaces

"One central idea missing from the decision cycle model is the notion that goals are often not fully formed in an agent's mind. As anyone who has ever tried to write an essay knows, we do not always act by moving through a decision sequence where we have a clear idea of our goal. Often we explore the world in order to discover our goals. We use the possibilities and resources of our environment to help shape our thoughts and goals, to see what is possible, and we have no clear idea of what we want to do any more than we always have a clear idea of what we are going to write before we begin the process of writing. This is a different orientation than the classical Cartesian view that we know things internally and just communicate fully intact thoughts in external vehicles. In this more dynamic interactionist view, the action of externally formulating thoughts is integral to internally formulating them too. We do not have a clear and distinct idea in mentalese awaiting expression in English or French. The very action of putting 'thoughts' in words helps to formulate them. If this is generally true about many of our actions it means that the goal of an interactive interface is not merely to allow users to do what they want to do, it must also allow them to discover what they want to do. ...

The overhaul I propose to the decision cycle model begins by noting that the way we cope with badly formulated goals and plans is by relying on two facts: we tend to operate in the same workplace over time, and we are usually clever enough to figure out on-line what we must do next. If one observes most creative activity it is apparent that there are both planful and improvisational elements to it. Creative activity is improvisational because agents are opportunistic -- they pursue ideas and possibilities as they emerge regardless of whether those ideas or possibilities have been anticipated. Creative activity is planful because the skilled agent tries to prepare the environment so that he or she has the greatest chance of stumbling on excellent ideas and possibilities. Thus, although an agent may not know, in advance, what he will create, he knows that by doing certain actions, or by arranging the environment in a certain way, or by laying out certain tools, he is doing the best he can to put himself in a position to recognize unimagined possibilities. This setting up the environment to facilitate on-line choice and improvisation I call preparation. It is a key component of skilled activity. There are others. To accommodate them in a decision model requires adding new forms of action, and new forms of interactivity throughout the decision cycle."

Motive Architecture: spaces which engage social interaction

"Architecture traditionally has been considered the spatial backdrop to social interaction. But increasingly architects enabled by computational technologies are creating spaces that can engage actively within these social interactions. My research focuses on the non verbal aspects of human computer interaction, embedding kinetic behaviours into physical objects. ...

While increasing numbers of designers are using robotic systems to build novel performative objects and spaces, there is little discourse in design on what forms of motion are most engaging and why? I am exploring how, and when, we percieve animism and causality in moving objects as I hypothesise that the most salient of motions are those which give a subjective impression that something is alive. My research examines the minimal amount of motion required to elicit immediate and seemingly irresistible interpretations of life gaining inspiration from the perceptual research of Michotte (1946), Heider and Simmel (1944), and Tremoulet and Feldmann (2006). A test rig for suspending and animating simple geometric figures has been developed to test methods of eliciting anima. Computer vision systems have been developed in parallel to observe human levels of engagement and to explore novel forms of exchange between architecture and inhabitant."
