Method and system for associating content with map zoom function

Abstract: Various methods, systems and apparatus for displaying content associated with a point-of-interest (“POI”) in a digital mapping system, are disclosed. One such method may include detecting a change in the zoom level of an electronic map displayed on a computing device, determining if the new zoom-level is at a pre-determined zoom level (e.g. at maximum zoom), identifying a POI on the map, retrieving content associated with the POI (“POI content”) and displaying the POI content. The method may further include detecting a change in the zoom, or pan, of the digital map while POI content is displayed, and removing the POI content in response. One apparatus, according to aspects of the present invention, may include means of detecting a change in the zoom level in a digital map displayed through an application (e.g. a web browser, an application on web-enabled cellular phones, etc., displaying a map generated by a service such as Google Maps®, Yahoo! Maps®, Windows Live Search Maps®, MapQuest®, etc.) on a computing device (e.g. personal computer, workstation, thin client, PDA, cellular phone/smart phone, GPS device, etc.) means of identifying a POI at the pre-determined zoom level, means of obtaining content associated with the POI, and means of displaying the POI content. POI content may be retrieved from a database (e.g. internet-based database); or, in an alternate embodiment, gathered by crawling websites associated with the POI. In one embodiment, POI content may be displayed as an image (e.g. a PNG file, GIF, Flash® component, etc.) superimposed on the digital map (e.g. as an overlay object on the map image.) In alternate embodiments, POI content may replace the digital map and may contain links to other content.

Global start-ups: Entrepreneurs on a worldwide stage

Abstract: Executive Overview If the mouse connected to your personal computer is made by Logitech, Inc.—and there's a good chance it is—then you're plugged into the growing phenomenon of global start-ups. Most people expect new ventures to begin domestically and for their international operations to evolve slowly, but global start-ups are international at inception. Logitech was founded in 1982 by a Swiss and two Italians who had global aspirations from the beginning. The venture was headquartered in both California and Switzerland. The firm's R&D and manufacturing were also split between California and Switzerland, and then quickly spread to Taiwan and Ireland. By 1989, it had revenues of $140 million and 30 percent of the worldwide market for those ubiquitous computer rodents. Was the Logitech experience unique, or might there be a pattern underlying the creation dynamics and success characteristics of global start-ups? To answer these questions, we analyzed twelve such start-ups, and personally interviewed sever...

Green Cloud Computing: Balancing Energy in Processing, Storage, and Transport For processing large amounts of data, management and switching of communications may contribute significantly to energy consumption and cloud computing seems to be an alternative to office-based computing.

Abstract: Network-based cloud computing is rapidly expanding as an alternative to conventional office-based computing. As cloud computing becomes more widespread, the energy consumption of the network and computing resources that underpin the cloud will grow. This is happening at a time when there is increasing attention being paid to the need to manage energy consumption across the entire information and communications technology (ICT) sector. While data center energy use has received much attention recently, there has been less attention paid to the energy consumption of the transmission and switching networks that are key to connecting users to the cloud. In this paper, we present an analysis of energy consumption in cloud computing. The analysis considers both public and private clouds, and includes energy consumption in switching and transmission as well as data processing and data storage. We show that energy consumption in transport and switching can be a significant percentage of total energy consumption in cloud computing. Cloud computing can enable more energy-efficient use of computing power, especially when the computing tasks are of low intensity or infrequent. However, under some circum- stances cloud computing can consume more energy than conventional computing where each user performs all com- puting on their own personal computer (PC).

Virtual reality-enhanced stroke rehabilitation

Abstract: A personal computer (PC)-based desktop virtual reality (VR) system was developed for rehabilitating hand function in stroke patients. The system uses two input devices, a CyberGlove and a Rutgers Master II-ND (RMII) force feedback glove, allowing user interaction with a virtual environment. This consists of four rehabilitation routines, each designed to exercise one specific parameter of hand movement: range, speed, fractionation or strength. The use of performance-based target levels is designed to increase patient motivation and individualize exercise difficulty to a patient's current state. Pilot clinical trials have been performed using the above system combined with noncomputer tasks, such as pegboard insertion or tracing of 2D patterns. Three chronic stroke patients used this rehabilitation protocol daily for two weeks. Objective measurements showed that each patient showed improvement on most of the hand parameters over the course of the training. Subjective evaluation by the patients was also positive. This technical report focuses on this newly developed technology for VR rehabilitation.

Influence of experience on personal computer utilization: testing a conceptual model

Abstract: The influence of prior experience on personal computer utilization was examined through an extension of a conceptual model developed and tested previously. Respondents were classified on the basis of their self-reported skill level and length of time having used personal computers. Three competing ways of modeling the influence of experience were tested: (1) a direct influence, (2) an indirect influence through six distinct attitude and belief components, and (3) a moderating influence on the relations between the attitude/belief components and utilization. The results suggested that experience influenced utilization directly, that indirect influences were present but less pronounced, and that the moderating influence of experience on the relations between five of six antecedent constructs and utilization was generally quite strong. For researchers, the implications are that prior experience with an information technology (IT) is an important factor to include when developing, testing, or applying models of IT adoption and use. For practitioners, the results highlight the importance of emphasizing applicability of the information technology to the current job and professional development early in the adoption process, with more emphasis on future benefits as experience is gained.
