isolated pairs of user input and system output. However, when the properties of a product, such as its shape, change our perceptions will follow these changes through a process of adaptation [12]. A product that changes its shape can potentially give rise to a feedback loop playing on the action-perception possibilities, offering a dynamic interaction between the action of the user and the reaction of the product, which has been named interactive materiality [34]. Our perspective on designing shape-changing interfaces and evaluating emerging interactions takes this broader perspective.
The focus is on interaction supported by manipulation, gesture, and touch, with medium sized (hand scale) objects. Lederman and Klatzky [28] provided a systematic framework for analyzing hand movements and manipulations that are conducted in the context of the active explorations people make in order to perceive with touch, what Gibson [12] called active touch. Specifically, Lederman and Klatzky [28] identified the necessity and demonstrated the appropriateness of a small set of stereotypical movements for perceiving the shape of different objects: lateral motion, pressure, static contact, unsupported holding, enclosure, contour following, function test, and part motion test. This framework is not directly related to shape-changing interfaces or current models thereof; yet it helps generate design ideas and identify ways one may engage with shape-changing interfaces.
Design Processes In a one week-long design boot camp, we invited 20 advanced Master level students in industrial design to use a parallel design process to develop shape-changing interfaces that feature variations on the interactive action-perception loop. The shape-changing interfaces were to sense the explorations that the user makes through active touch [12] and adapt their physical properties. Students
were instructed to design artifacts that support different explorations of users along the classification of typical movement patterns for exploratory procedures (EPs). A collection of ten shape-changing artifacts was created (Figure 1). Videos of the artifacts can be viewed at http://www.anonymous.com.
These first design explorations were followed by a more sustained and in-depth design process, where a design researcher synthesized the initial design concepts, redesigned the initial artifacts in order to create a collection of six shape changing interfaces featuring very distinct experiences of shape-change.
The processes described above resulted in six artifacts, illustrated in Figure 2 through Figure 7. The accompanying video details the interaction possible with the artifacts. These six artifacts were used in the study presented next.

right figure shows two artifacts.
Figure 2. PIEGA explores dynamic changes in form as a response to static contact and consists of a cloth surface
attached in the center to a servomotor. The rotation of the servomotor results in folds in the cloth surface. A capacitive sensor is used to determine user presence and static contact.
Figure 3. GATO explores dynamic changes in texture as a response to static contact and consists of a platform with spring steel loop ‘hairs’ that lowers and rises to alter the length of the ‘hairs’; short hairs are rougher to the touch than longer hairs.
A capacitive sensor is used to determine user presence and static contact.

Hand Movements: A Window into Haptic Object Recognition

Two experiments establish links between desired knowledge about objects and hand movements during haptic object exploration. Experiment 1 used a match- to-sample task, in which blindfolded subjects were directed to match objects on a particular dimension (e.g., texture). Hand movements during object exploration were reliably classified as “exploratory procedures,” each procedure defined by its invariant and typical properties. The movement profile, i.e., the distribu- tion of exploratory procedures, was directly related to the desired object knowl- edge that was required for the match. Experiment 2 addressed the reasons for the specific links between exploratory procedures and knowledge goals. Hand move- ments were constrained, and performance on various matching tasks was as- sessed. The procedures were considered in terms of their necessity, sufficiency, and optimahty of performance for each task. The results establish that in free exploration, a procedure is generally used to acquire information about an object property, not because it is merely sufficient, but because it is optimal or even necessary. Hand movements can serve as “windows,” through which it is pos- sible to learn about the underlying representation of objects in memory and the processes by which such representations are derived and utilized. o 1987 Academic

When we feel extremely helpless in a situation, we commonly say, “My hands are tied!” Indeed, it is hard to imagine a world in which we cannot feel the soft fur of a kitten or even tie our shoelaces. Yet, psy- chology has often portrayed the hand as a second-class citizen. Research
