Viewpoint: Homeostasis as Inspiration—Toward Interactive Materials

Homeostatic systems combine an ability to maintain integrity over time with an incredible capacity for interactive behavior. Fundamental to such systems are building blocks of “mini-homeostasis”: feedback loops in which one component responds to a stimulus and another opposes the response, pushing the module to restore its original configuration. Particularly when they cross time and length scales, perturbation of these loops by external changes can generate diverse and complex phenomena. Here, it is proposed that by recognizing and implementing mini-homeostatic modules—often composed of very different physical and chemical processes—into synthetic materials, numerous interactive behaviors can be obtained, opening avenues for designing multifunctional materials. How a variety of controlled, nontrivial material responses can be evoked from even simple versions of such synthetic feedback modules is illustrated. Moreover, random events causing seemingly random responses give insights into how one can further explore, understand and control the full interaction space. Ultimately, material fabrication and exploration of interactivity become inseparable in the rational design of such materials. Homeostasis provides a lens through which one can learn how to combine and perturb coupled processes across time and length scales to conjure up exciting behaviors for new materials that are both robust and interactive.     

Interactivity,engagement, and technology dependence: understanding users’ technology utilisation behaviour

To better understand users’ technology utilisation behaviour, a construct named technology dependence is suggested; as well a technology dependence model is proposed and empirically tested. Based on the literature on marketing, information systems’ utilisation, and psychology, a comprehensive set of constructs and hypotheses are compiled with a methodology for testing them in this paper. A questionnaire was designed and data were collected from 255 users of smartphones in Korea, mainly consisting of students and academics. Structural equation modelling was then applied to analyse the data. The result indicated that engagement is the strongest indicator of technology dependence along with user satisfaction. User satisfaction is affected by engagement and responsiveness of the technology. And all three dimensions of interactivity, namely, control, communication, and responsiveness, are revealed to be significant indicators of engagement. Based on the findings, the model develops useful insights into the factors that influence technology dependence and provides new ideas in understanding technology utilisation.     

Smart TV: are they really smart in interacting with people? Understanding the interactivity of Korean Smart TV

Smart TV (STV), a new digital television service, has been rapidly developing, particularly in Korea. With the conceptual model of interactivity, this study empirically investigates the effects of perceived interactivity on the motivations and attitudes towards STV in Korea. The model is created to validate the relationship of perceived interactivity to performance, attitude and intention. Further, the model examines the mediating roles of perceived interactivity in the effect of performance on attitude towards STV. Empirical evidence supports the mediating role of perceived interactivity. Implications of the findings are discussed in terms of building a theory of interactivity and providing practical insights into developing a user-centred STV interface.

局部颜色模型的交互式Graph-Cut分割算法

由于目前大多数交互式Graph-Cut分割算法很难达到精确分割且实时交互的效果.对此,提出一种基于局部颜色模型的改进算法.该算法利用Mean-Shift预分割,建立基于局部颜色模型的交互式分割框架,并将像素级的Graph-Cut算法转化为基于区域的算法进行快速求解.预分割之后的区域保持了原有图像的结构,不仅提高了采用局部颜色模型估计分布的准确性,而且基于区域Graph-Cut的算法明显降低了计算的复杂度.实验结果表明,改进后的算法不仅保证了分割的精确性,而且还达到了实时交互.     

Kinaesthetic thinking: The tacit dimension of interaction design

Designers of computer-based material are currently forced by the available design tools to express interactivity with concepts derived from the logical-mathematical paradigm of computer science. For designers without special training as programmers this represents a barrier. The three psychological experiments presented here indicate that it is possible to express interactive behavior in a more direct fashion by letting the designers compose software from interaction elements with built-in behavior. The resulting “kinaesthetic thinking” of the software designers shows similarities with visual and musical thinking. To be able to support this style of design it might be necessary to rebuild from scratch parts of today's software using simple interactive building blocks. As an illustration, a design tool is presented, based on a pixel-level agent architecture.
