基于德温特专利数据库,以1998—2017年中美可穿戴设备专利信息为依据,运用社会网络分析方法,对两国可穿戴设备产业合作网络的网络结构和演化规律进行比较研究。结果表明,两国可穿戴产业合作创新网络规模不断扩大,中国专利权人间的合作程度不如美国高。中国企业控制着网络的大部分资源,而美国的个体研究者与少数大型企业共同控制着网络的资源。两国的专利技术领域不断完善,但中国缺乏前端核心专利,可穿戴技术创新的速度落后于美国。总的来说,中国的可穿戴产业发展与美国仍有一定差距,需要个体、企业和政府共同促进合作创新。 相似文献

科学技术的发展使技术人工物不断趋于智能化。智能可穿戴装置作为技术人工物的一种,以解决人类生产和生活问题的功能性装置为主。现代科学不仅要关心如何为智能可穿戴装置提供技术应用,还要思考如何将道德价值和伦理责任设计到智能可穿戴装置中,这是智能人工物技术治理中不容忽视的问题。本文通过技术现象学还原法,追溯了智能可穿戴装置的价值和责任问题,分析了其起源和范围以及责任划分,以期为智能可穿戴设计中的技术伦理问题提供一些参考。最后得出智能可穿戴装置的价值分为其技术设计价值、道德伦理主体价值,责任则是四个主要责任主体由设计师和工程师、智能可穿戴装置、用户和政府监管单位形成了一个责任闭环。 相似文献

Sedentarism is a common problem that can affect human health and wellbeing. Predicting sedentary behaviour is an emerging area that can benefit from data collected from sensors available in ubiquitous devices, such as wearables and smartphones. In this paper, we present an approach aiming at predicting the sedentary behaviour of a user from data collected from sensors installed in wearable/mobile devices. We compare personal and impersonal models using a real-life dataset consisting of sensing data of 48 users during 10 weeks. We found that impersonal models using Deep Neural Networks were able to accurately predict the subject’s future sedentary behaviour. 相似文献

Despite the widespread adoption of the wearable fitness tracker (WFT), the phenomenon of acceptance-discontinuance has limited their value. This phenomenon has called attention to the issue of continued WFT use, with emphasis on how the value of the WFT can be sustained. Using the concept of value co-creation, this research aims to understand the effects of actor-to-actor interactions on continued use of a WFT, with a specific focus on the interactions generated through two WFT services: choice and involvement of dietitians. Considering a WFT’s service system as part of the greater healthcare ecosystem, this paper also considers the moderating role of self-efficacy in health management as an internal factor and healthcare system satisfaction as an external factor. A randomized experimentation using a scenario-based survey was conducted, and the data generated by 423 participants were analyzed. The results emphasize the significant positive effect of dietitian involvement on users’ intentions to continue using their WFT. Dietitian involvement not only improves continued use intention, but also realizes the effect of choice. The positive effect of dietitian involvement is robust, regardless of user satisfaction with the healthcare service system. Self-efficacy in health management also plays a key role in positively moderating the effect of choice on continued use intention. This study expands information system literature by providing theoretical insights into continued use from the perspective of value-co-creation. Our findings also have implications for the development of service systems for fitness wearables. 相似文献

This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors. 相似文献

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction. 相似文献

Electronic data interchange (EDI) provides means for interorganizational communication, creates network externalities, requires an advanced information technology (IT) infrastructure, and relies on standards. In the diffusion of such innovations, institutional involvement is imperative. Such institutions contain governmental agencies, national and global standardization organizations, local government, and nonprofit private organizations like industry associations. The last type of organizations we call intermediating institutions. They intermediate or coordinate ("inscribe") the activities of a group of would-be adopters. Unfortunately, little is known of how these organizations shape the EDI diffusion trajectory. In this article we examine one specific type of intermediating organizations?industry associations?and how they advanced the EDI diffusion process in the grocery sectors of Hong Kong, Denmark and Finland. We identify six institutional measures, placed into a matrix formed by the mode of involvement (influence vs. regulation) and the type of diffusion force (supply push vs. demand pull), that can be mobilized to further the EDI diffusion. Industry associations were found to be active users of all these measures to varying degrees. Their role was critical especially in knowledge building, knowledge deployment, and standard setting. Furthermore, institutional involvement varied due to policy and cultural contingencies and power dependencies. 相似文献

With great care, Dr. ZHOU Zhonghe takes out a package wrapped by cotton tissue from a drawer and says: "This is the gem of our collections: the fossil of a bird that lived 125 million years ago!" Then, pointing at a tiny mound, he explains: "Look, this is the claw and that is the head. It was in the egg shell and ready to hatch ... The species fell into a family of waterside inhabitants." 相似文献
