“…More precisely, a planar view is defined as a view in which (1) the major axis of the object is approximately perpendicular or parallel to the line of sight and (2) one axis is foreshortened. Further, if an object has flat surfaces, adults prefer to view the object so that the flat surface is perpendicular to the line of sight (Harman, Humphrey, & Goodale, 1999; Harries et al, 1991; James, Humphrey, & Goodale, 2001; James et al, 2002; Keehner, Hegarty, Cohen, Khooshabeh, & Montello, 2008; Locher, Vos, Stappers, & Overbeeke, 2000; Niemann, Lappe, & Hoffmann, 1996; Perrett & Harries, 1988; Perrett et al, 1992). Some studies suggest that subsequent object recognition benefits from object views that conform to these biases (James et al, 2001), a result that implies that these views may build better object representations.…”

Object recognition depends on the seen views of objects. These views depend in part on the perceivers’ own actions as they select and show object views to themselves. The self-selection of object views from manual exploration of objects during infancy and childhood may be particularly informative about the human object recognition system and its development. Here, we report for the first time on the structure of object views generated by 12 to 36 month old children (N = 54) and for comparison adults (N = 17) during manual and visual exploration of objects. Object views were recorded via a tiny video camera placed low on the participant’s forehead. The findings indicate two viewing biases that grow rapidly in the first three years: a bias for planar views and for views of objects in an upright position. These biases also strongly characterize adult viewing. We discuss the implications of these findings for a developmentally complete theory of object recognition.

“…Movement plots, that are a result of the experiment in which we evaluated the active and following behavior, are used as inspiration. We made movement plots [19] of the activity of all participants. Apparent from all these movement plots was that (1) participants have a certain approach that is recognizable in both the behaviors they experience and (2) that there are different parameters that characterize the exploration.…”

Perceptual crossing is the reciprocal interplay of perceiving while being perceived. In this paper we discuss the last iteration of our ongoing research project on designing for perceptive qualities in systems of interactive products. We describe the design of explorative behavior in an artifact to enable the artifact and a person to engage in perceptual crossing. The explorative behavior is compared to the following and active behavior, the results of two earlier iterations. Through the iterations we formulated, applied and evaluated design relevant knowledge in the form of seven design notions. These notions inform designresearchers and design-practitioners on how to design for perceptive qualities in systems of interactive products. Here we specifically focus on how the artifact detects active perceptive behavior of a person, and how the artifact becomes aware of bygone perception and anticipates on future perception. An experiment shows how participants preferred the resulting explorative behavior that is closest to our theoretical framework based on phenomenology.

“…Does the balanced structure of a three-dimensional (3-D) object, such as a sculpture, also influence the way people look at it? To answer this question, Locher, Vos, Stappers, and Overbeeke (2000) developed a tracking system capable of recording the way viewers examine 3-D objects. The system, illustrated and described in Figure 2, monitors and records the inspection behavior of someone free to select any viewing angle of an object by moving about it while at the same time being able to rotate it.…”

“…Figure 2. The experimental set-up used by Locher et al (2000) to monitor visual inspection behavior of an observer (1) free to select any viewing angle of a 3-D object by moving about it while at the same time being able to rotate it on a turntable (2). The observer wears an eyeglass frame to which a small reflecting dot is attached at a point between the eyes.…”
