Exploring interactivity: user ability and the Chinese diaspora

Abstract

This paper focuses on two areas of enquiry, the phenomenon of interactivity and how ideas from outside of interaction design can expand our understanding of interactivity. Although generally seen as the user's ability to access information, interactivity's capacity can extend to the shaping of content and meaning. The paper proposes that visualities produced by diasporic individuals reveal the potential of users for reflexivity and intervention. It draws on theories of postcolonial identity and the mixing of cultural meanings of diasporic people to highlight the importance of allowing users to experience autonomy, agency and self-determination in digital media.     

The cognitive impact of interactive design features for learning complex materials in medical education

To identify the most effective way for medical students to interact with a browser-based learning module on the symptoms and neurological underpinnings of stroke syndromes, this study manipulated the way in which subjects interacted with a graphical model of the brain and examined the impact of functional changes on learning outcomes. It was hypothesized that behavioral interactions that were behaviorally more engaging and which required deeper consideration of the model would result in heightened cognitive interaction and better learning than those whose manipulation required less deliberate behavioral and cognitive processing. One hundred forty four students were randomly assigned to four conditions whose model controls incorporated features that required different levels of behavioral and cognitive interaction: Movie (low behavioral/low cognitive, n = 40), Slider (high behavioral/low cognitive, n = 36), Click (low behavioral/high cognitive, n = 30), and Drag (high behavioral/high cognitive, n = 38). Analysis of Covariates (ANCOVA) showed that students who received the treatments associated with lower cognitive interactivity (Movie and Slider) performed better on a transfer task than those receiving the module associated with high cognitive interactivity (Click and Drag, partial eta squared = .03). In addition, the students in the high cognitive interactivity conditions spent significantly more time on the stroke locator activity than other conditions (partial eta squared = .36). The results suggest that interaction with controls that were tightly coupled with the model and whose manipulation required deliberate consideration of the model's features may have overtaxed subjects' cognitive resources. Cognitive effort that facilitated manipulation of content, though directed at the model, may have resulted in extraneous cognitive load, impeding subjects in recognizing the deeper, global relationships in the materials. Instructional designers must, therefore, keep in mind that the way in which functional affordances are integrated with the content can shape both behavioral and cognitive processing, and has significant cognitive load implications.

The impact of online brand community characteristics on customer engagement: An application of Stimulus-Organism-Response paradigm

The advent of interactive digital platforms has led people to progressively interact on such platforms, urging organizations to create online communities to engage customers with them and with each other to enhance brand loyalty. This study attempts to investigate what motivates customers to engage in these brand communities. Through a questionnaire survey of 430 Facebook users, this study investigates whether and how the unique characteristics (information quality, system quality, virtual interactivity, and rewards) of online brand communities affect customer engagement. The consequent effect of customer engagement on brand loyalty is also examined. This study frames and empirically validates a model for engaging customers with online brand communities on Facebook, considering the moderating role of gender. The Stimulus-Organism-Response paradigm is solicited to justify the theoretical background of this study. The data were analyzed using structure equation modelling. Results reveal that each of the characteristics positively influences customer engagement, with information quality and virtual interactivity bearing the strongest influence. Customer engagement also exhibits a strong positive impact on brand loyalty. This results further reveal that gender gap in the online environment is declining as the impact of all the four characteristics of online brand communities on customer engagement was invariable across male and female members.     

Error Biases in Spoken Word Planning and Monitoring by Aphasic and Nonaphasic Speakers: Comment on Rapp and Goldrick (2000).

B. Rapp and M. Goldrick (2000) claimed that the lexical and mixed error biases in picture naming by aphasic and nonaphasic speakers argue against models that assume a feedforward-only relationship between lexical items and their sounds in spoken word production. The author contests this claim by showing that a feedforward-only model like WEAVER++ (W. J. M. Levelt, A. Roelofs, & A. S. Meyer, 1999b) exhibits the error biases in word planning and self-monitoring. Furthermore, it is argued that extant feedback accounts of the error biases and relevant chronometric effects are incompatible. WEAVER++ simulations with self-monitoring revealed that this model accounts for the chronometric data, the error biases, and the influence of the impairment locus in aphasic speakers.

Debouncing the speech button: A sliding capture window device for synchronizing turn-taking

When human beings converse, they alternate between talking and listening. Participating in such turntaking behaviors is more difficult for machines that use speech recognition to listen and speech output to talk. This paper describes an algorithm for managing such turn-taking through the use of a sliding capture window. The device is specific to discrete speech recognition technologies that do not have access to echo cancellation. As such, it addresses those inexpensive applications that suffer the most from turn-taking errors—providing a “speech button” that stabilizes the interface. Correcting for short-lived turn-taking errors can be thought of as “debouncing” the button. An informal study based on ten subjects using a voice dialing application illuminates the design.     

基于视听感官通道的交互性环境学习有效性研究

研究交互环境对于学习效果的影响,通过在受测验者的听觉、视觉感官组合变化所产生的通道效应下,探究在非交互教学、交互教学以及交互程度不同的教学环境下的学习效果有效性。设计组合式教学测验,把视觉、听觉不同通道的组合方式,与交互性高低程度不同的教学方式结合,来分析学习者的学习效果。通过测验获取数据并分析,探究不同环〖JP2〗境下的学习有效性。本文实验表明交互学习环境中通道效应对于学习有促进作用,不同交互程度的学习环境对于通道效应的影响也是不一样的,一定程度的交互学习环境对于学习有促进作用,而交互程度较高的学习环境反而会起消极作用。
