The human-computerinteraction community has long been concerned with design. Terms such as 'creativity' and 'innovation' are frequently used when referring to the design process and in this paper we examine what creativity is with respect to design. Design is often a collaborative and, therefore, a social activity. We review the evolution of definitions of creativity, leading to our proposal of a unified definition, we present a theoretical account of why social creativity should in principle be more productive than individual creativity. We explain findings to the contrary in terms of three social influences on creativity and suggest that research in supporting design should focus on mitigating the effects of these social influences on the creativity of design teams.

Numerous guidelines for making websites more accessible for older users have been proposed, but few provide evidence from such users for their recommendations This study investigated effects of line spacing and text justification on younger (24 - 31 years) and older (65 - 78 years) adults' performance and preferences in web reading tasks. The three levels of line spacing (single, 1.5, and double) and 2 types of text justification (left only and left-right) were studied. Neither variable had a significant effect on performance measures, although both younger and older adults preferred 1.5 or double spacing over single spacing. There were no significant differences in preferences for left versus left-right justification. These results suggest that contrary to common recommendations, 1.5 or double spacing should be recommended for all users, not only older users and that no recommendation is needed on text justification.

Objective: Fibromyalgia (FM) is a syndrome marked by chronic pain, fatigue, and mood disorders. Nonpharmacologic strategies are recommended to avoid overuse of opioids or nonsteroidal anti-inflammatory drugs, but current approaches often provide limited relief. This study aimed to preliminarily assess the efficacy and feasibility of a new combined intervention of immersive virtual reality with multisensor biofeedback (IVR-BF) in FM management. Methods: In this single-center, pilot, open-label, randomized controlled trial, adult patients with FM were randomly assigned 1:1 to either the treatment (TR) group, receiving IVR-BF immediately, or a waitlist control (WL) group, receiving IVR-BF after the TR group completed treatment. The primary outcome was reduction in visual analog scale (VAS) pain scores in the TR group, after five IVR-BF sessions, compared to the WL group, after the waiting period. Secondary outcomes included improvements in FM impact (FM Impact Questionnaire [FIQ] score) and qualitative aspect of pain (Short-form McGill Pain Questionnaire [SF-MPQ] score). A longitudinal analysis was conducted across all patients to examine the trends in VAS pain, SF-MPQ, and FIQ score during the trial. Results: Fifty patients were screened, and 20 female patients (10 TR and 10 WL) completed the trial and were analyzed. Those in the TR group showed significantly lower VAS pain scores compared to those in the WL group (P = 0.011), along with significant improvement in the FIQ score (P = 0.018). The longitudinal analysis revealed progressive improvements in VAS pain, SF-MPQ, and FIQ score, supported by physiologic improvements (heart rate variability, respiratory rate, skin conductance). No significant safety concerns were reported. Patients expressed a high level of satisfaction with the IVR experience. Conclusion: IVR-BF is a feasible treatment that shows potential in reducing pain and improving quality of life in patients with FM, supporting the need for larger trials t

More modes are. better than one when it corner fa comprehending human speech, especially when, speakers are accented or interacting innoisy natural environments.A MULTIMODAL ARCHITECTURE CAN FUNCTION MORE ROBUSTLY THAN ANYindividual recognition technology that is inherently error prone, includingspoken-language systems. One goal of a well-designed muhimodal system is the integration of complementary input modes to create a synergistic blend, permitting the strengths of each mode to overcome weaknesses in the other modes and to support "mutual compensation" of recognition errors.

Multimodal interaction serves an important role in human-computerinteraction. In this paper we propose a multimodal interaction model based on the latest cognitive research findings. The proposed model combines two proven neural computations, and helps to reveal the enhancement or depression influence of multimodal presentation upon the corresponding interaction task performance. A set of experiments is designed and conducted within the constraints of the model, which demonstrates the observed performance enhancement and depression effects. Our exploration and the experimental results help to further solve the question about how tactile feedback signal contribute the multimodal interaction efficiency which could provide guidelines for designing the tactile feedback in multimodal interaction.

Perception of charts is a challenging task for blind and visually impaired people. Nevertheless, charts are an important tool to analyse data. Appropriate output media are required to make data analysis more accessible. We propose a semantic preserving workflow as well as tooling requirements to integrate the generation process of accessible charts. Towards getting there, we present our current prototypical state and specify further steps. Copyright (C) 2017 bei den Autoren.
