7 Things You Should Know

Multi-touch interfaces are input devices that recognize two or more simultaneous touches, allowing one or more users to interact with computer applications through various gestures created by fingers on a surface. Some devices also recognize differences in pressure and temperature. Multi-touch technology introduces users to swipes, pinches, rotations, and other actions that allow for richer, more immediate interaction with digital content. Multi-touch devices and supporting applications offer diverse ways of visualizing information to improve understanding, and they facilitate new ways to foster collaborative creation, permitting several users to work simultaneously on a single screen.

The "7 Things You Should Know About..." series from the EDUCAUSE Learning Initiative (ELI) provides concise information on emerging learning technologies. Each brief focuses on a single technology and describes what it is, where it is going, and why it matters to teaching and learning. Use these briefs for a no-jargon, quick overview of a topic and share them with time-pressed colleagues.

Ning is an online service that allows users to create their own social networks and join and participate in other networks. No technical skill is required to set up a social network, and there are no limits to the number of networks a user can join. Users of Ning social networks have access to functionality similar to that of more well-known social networks, such as Facebook and MySpace. Various features allow users to read news or learn about related events, join groups, read and comment on blog entries, view photos and videos, and other activities as set up by the network creator. RSS feeds let users subscribe to updates from specific parts of the social network.

Google Apps is a collection of web-based programs and file storage that run in a web browser. The applications include communication tools (Gmail, Google Talk, and Google Calendar), productivity tools (Google Docs: text files, spreadsheets, and presentations), a customizable start page (iGoogle), and Google Sites (to develop web pages). Google stores all of the files and content centrally and keeps a record of the different versions of a file. With Google Apps, sharing content is as simple as granting someone access, which facilitates collaboration, peer review of academic materials, and the collective generation of knowledge.

Flickr is a photo-sharing website where anyone can upload and tag photos, browse others' photos, and add comments and annotations. Users can create photo sets and collections to manage content and participate in topical groups to cultivate a sense of community. Although Flickr is ostensibly for photos, the site might more aptly be described as a venue for sharing experiences and building relationships. The site provides the tools, but the value derives from the contributions of the user community -- photos, comments, ratings, and organization -- and the connections that the site facilitates between individuals. In this way, Flickr embodies what has come to be known as Web 2.0 technology.

Lulu is a web-based self-publishing service, providing online access to the tools an individual needs to design, publish, and print original material, including books, brochures, reports, calendars, and posters. Self-publishing offers an alternative to traditional publishing by allowing authors and creators of content to decide what gets published and in what form, allowing anyone to publish a book inexpensively and much more quickly than with traditional publishing. Faculty can use the service to publish more timely textbooks and other material for courses, and by having access to the tools of production, students can see and understand the processes involved.

Skype is a voice over Internet protocol (VoIP) application that lets users make free phone calls between Skype-equipped computers and inexpensive calls between Skype computers and landline or cell phones. Skype functions on a P2P model rather than as a centralized application, and it offers features such as voicemail, call forwarding, conference calling, and video chat. In most circumstances, Skype provides access to voice and video communication for a fraction of what other options cost. It allows more frequent contact between colleagues, collaborators, and friends and permits connections with those not likely to be in touch through conventional phone systems.

Citizen journalism refers to a wide range of activities in which everyday people contribute information or commentary about news events. With the birth of digital technologies, people now have unprecedented access to the tools of production and dissemination. Citizen journalism epitomizes the belief that the experiences of people personally involved with an issue present a different -- and often more complete -- picture of events than can be derived from the perspective of an outsider. Citizen journalism encompasses content ranging from user-submitted reviews on a Web site about movies to wiki-based news. It forces contributors to think objectively, asking probing questions and working to understand the context -- the kinds of activities that lead to deeper learning.

Data visualization is the graphical representation of information. Information technology combines the principles of visualization with powerful applications and large data sets to create sophisticated images and animations. Representing large amounts of disparate information in a visual form often allows you to see patterns that would otherwise be buried in vast, unconnected data sets. Data visualizations offer one way to harness infrastructure to find hidden trends and correlations that can lead to important discoveries. Visual literacy is an increasingly important skill, and data visualizations are another channel for students to develop their ability to process information visually.

Haptics technologies provide force feedback to users about the physical properties and movements of virtual objects represented by a computer. Human-computer interaction is largely visual -- words, data, or images on a screen. Input devices such as the keyboard or the mouse translate human movements into actions on the screen but provide no feedback to the user about those actions. Haptics incorporates both touch (tactile) and motion (kinesthetic) elements. For applications that simulate real physical properties -- such as weight, momentum, friction, texture, or resistance -- haptics communicates those properties through interfaces that let users "feel" what is happening on the screen.

Cyberinfrastructure is not a new technology, per se, or merely a better, faster Internet. While cyberinfrastructure brings together high-performance computing, remote sensors, large data sets, middleware, and sophisticated applications (modeling, simulation, visualization), it also involves people as participants in the generation of knowledge, giving them the opportunity to share expertise, tools, and facilities. Cyberinfrastructure merges technology, data, and human resources into a seamless whole.

Twitter is an online application that is part blog, part social networking site, and part cell phone/IM tool. It is designed to let users describe what they are doing or thinking at a given moment in 140 characters or less. As a tool for students and faculty to compare thoughts on a topic, Twitter could be used academically to foster interaction and support metacognition.

Wikipedia is a free online encyclopedia anyone can add to or edit. A highly popular resource, Wikipedia has become a primary research tool of college students, and it may help them develop comparative research skills. However, since Wikipedia’s entries don’t undergo verified expert review, many academics are concerned about its use for academic purposes.

Since ELI's first brief on Facebook (http://www.educause.edu/LibraryDetailPage/666?ID=ELI7017), the social networking site originally developed for college and university students has become available to anyone. It now offers new ways of organizing social networks as well as extensive new features and access to other Web applications. Users can now manage online identities and engage other users much more easily. They also enjoy privacy policies that give them unprecedented control over how their personal information is handled on the site.
