The ubiquity and educational potential of mobile applications are well acknowledged. This paper proposes six theory-based, pedagogical strategies to guide interaction design of mobile apps for young children. Also, to augment the capabilities of mobile devices, we used a humanoid robot integrated with a smartphone and developed an English-learning app that applied the design strategies to this environment. Our observations of children's one-on-one use support the promise of the strategies and the combined use of robots and mobile devices to be a viable option to help optimize mobile learning. 相似文献

Graphene-based actuators featuring fast and reversible deformation under various external stimuli are promising for soft robotics. However, these bimorph actuators are incapable of complex and programmable 3D deformation, which limits their practical application. Here, inspired from the collective coupling and coordination of living cells, we fabricated a moisture-responsive graphene actuator swarm that has programmable shape-changing capability by programming the SU-8 patterns underneath. To get better control over the deformation, we fabricated SU-8 micropattern arrays with specific geometries and orientations on a continuous graphene oxide film, forming a swarm of bimorph actuators. In this way, predictable and complex deformations, including bending, twisting, coiling, asymmetric bending, 3D folding, and combinations of these, have been achieved due to the collective coupling and coordination of the actuator swarm. This work proposes a new way to program the deformation of bilayer actuators, expanding the capabilities of existing bimorph actuators for applications in various smart devices. 相似文献

This article takes the concept and some of the existing applications of socialbots—software robots that operate on social networking sites and present themselves as human users—as an occasion to trace the evolution of online sociality. The argument mobilizes theories of social rationalization from Max Weber to contemporary critical theory to demonstrate that the appearance of automated profiles (socialbots) on social networking platforms can be seen as a logical step in the progressive enclosure of online social interaction in standardized, simplified, and trivialized forms, frames, and gestures. Critical questions concerning what the growth of robo-sociality may mean for individual users and the online public sphere are posed with a view to charting the directions for a needed public debate. 相似文献

机器人的研究应用领域不断拓宽,其中类人机器人的研究和应用尤其受到了普遍的关注,并成为智能机器人领域中最活跃的研究热点之一。研制与人类外观特征类似,具有人类智能、灵活性,并能够与人交流、不断适应环境的类人机器人一直是人类的梦想之一。本文阐述了采用了PIC系列单片机对机器人各功能子系统进行控制的同时,通过对舵机的优化控制使机器人具有多关节协调运动模仿人类动作的能力。 相似文献

自从奇虎360公司进军搜索引擎行业以来,其与百度公司之间的摩擦不断升级。百度在自己旗下的网站设置robots协议白名单,将360搜索引擎排除在外,而360则公然绕过robots协议,强行抓取百度网站页面。由于法律无明文规定,关于robots协议的法律效力值得探讨,但不管从哪个角度来分析,恶意越过ro-bots协议强行抓取网页或窥探隐私都应受到法律制裁,其具体是违反著作权法还是构成不正当竞争行为应视具体情况加以分析与选择。 相似文献

Fifty years of the compounding effects of Moore's Law have led to enormous advances in computer processing power. Increased network speeds, the availability of big data, and machine learning techniques have accelerated the development of artificial intelligence; this promises to dramatically change many industries, including libraries. This article offers some thoughts on the effects of automation on employment, the social and political fallout, and the threats and opportunities for academic and public libraries. 相似文献
