More Emerging Trends and Technologies

More Emerging Trends and Technologies April 17 – April 21

. Physiological Interaction: o Currently, you input data into the computer through physical devices. In the future, you may input into the computer through physiological means such as real body characteristics, such as breath, your voice, your height and weight, and even your eye (p. 427). o Automatic speech recognition (ASR) captures spoken words, but also distinguishes word groupings to form sentences. Microsoft Office 2003 and Office XP have ASR capabilities (p. 427).

. Virtual Reality: o In virtual reality, a 3-D computer simulation in which you actively and physically participate. In VR, you make use of special input and output devices that capture your physiological movements and send physiological movements back to you (p. 428). . Glove – an input device that captures the movement of your hand . Headset – an input device that captures the movement of your head; an output device that produces an image based on your movements. . Walker – an input device that captures the movement of your feet o A couple of VR applications include pilot training and doctor training (p. 429).

. CAVE Automatic Virtual Environments: o A CAVE is a special 3-D reality room that can display images of other people in other CAVES all around the world (p. 429). o In a CAVE room, numerous digital cameras capture images about you and someone in another CAVE room. They will appear to you just like they were in the room with you, and you will appear to them just like you were in the room with them (p. 429). o Because the digital cameras do all the work, you do not need any special equipment in a CAVE room (p. 430). . Biometrics: o Biometrics is the use of physiological characteristics, such as your fingerprints, the blood vessels in your eye, the sound of your voice, or even your breath, to provide identification (p. 430). o However, biometrics are not limited to supply identification as seen on the list on p. 431. o The best form of security for personal information encompasses three aspects: . What you know (ex - password) . What you have (ex – swipe card) . Who you are (ex – biometrics)

. Increasing Portability and Mobility: o Portability refers to how easy it is for you to carry around your technology. Mobility is what you have the ability to do with your technology while carrying it around (p. 434). o For example, digital cash is an electronic representation of cash. You pay the bank and they give you digital cash files in return. You find the product or service on the Internet that you wish to purchase and then send the digital cash files to the seller (p. 434). o Digital cash has several problems (435): . If your computer crashes and your digital cash files are lost, they are gone. . One bank’s digital cash files may not look like another bank’s digital cash files; therefore, it could be very easy to counterfeit. . Digital cash is sent over the Internet and is therefore, very easy to steal.

. Multi-state CPUs: o From the first lecture of this semester, we learned that computers worked in a system known as binary (either 1s or 0s). Multi-state computers will work with information representing more than just ten states (probably 10). Because they do not have to perform binary translation into decimal, they will be much faster (p. 437). . Rebirth of e-Commerce: o The author predicts a tremendous explosion in C2C commerce, as consumers sell more and more products to other consumers (p. 438).

o The author also predicts a tremendous broadening in “e-government” (p. 439): . G2G – e-commerce activities performed between multiple branches of government. . G2B – e-commerce activities performed between a government and its business partners . G2C – e-commerce activities performed between a government and its citizens . International G2G – e-commerce activities between foreign governments

. Miscellaneous Concepts: o An electronic portfolio (e-portfolio) is a cohesive, powerful, and well-designed collection of electronic documents that demonstrate your skills, education, professional development, and benefits you offer to a hiring organization (p. 455). o An electronic job market is emerging as more and more companies use the Internet to recruit potential employees (p. 455).
