However, the difference between “direct” and “indirect” perception is usually of secondary importance. Place the SENSOR PLATE between the tubes (2). Combine the HAMMER and the SPEAKER WITH MAGNET to take out the MAGNET. Attach the plate to the MAGNET (3). Exit the room and enter the left room on the right side. After they defeat the mutant Death Stalker, Merlot self-destructs his lab. These insights open up new possibilities for designers to help people deal with problems associated with modern uses of interactive technologies.
Therefore, some of the questions, central for putting direct perception of affordances on the agenda of HCI research are: Can the basic principles of ecological psychology allow for the existence of perception, which is not direct? Even some of Gibson’s examples, such as using a mailbox, do not easily lend themselves to analysis in terms of layouts, objects, events, and ambient light. Another important challenge is to make sure a concept is practically relevant and useful, that it provides new insights that help practitioners deal with concrete problems of analysis, design, evaluation, and appropriation of interactive technologies. Conclusion: Reflections on the present and future of the concept of affordances in HCI and interaction design.
Growth provides infants with more advanced action and sensory systems, and these new capabilities are employed by the infants to expand and differentiate their perceptual worlds. The team ultimately makes their way through the facility to a testing lab, where they encounter a mutant Death Stalker. Gibson and Pick also conclude that perceptual learning and development in infants is species-typical: it is generally similar for all infants of the same species. For instance, they can mean shelters, tools, paths, obstacles, collisions, and so forth. The discussion in Section 3 suggests that some “technology-specific” accounts of affordances can be offered by activity theory and phenomenology.
