Chapter 9 Notes
The Changing Internet
software-as-a-service (SaaS) is a delivery model for software in which you pay for software on a pay-per-use basis
in the SaaS model you pay for software on a pay-per-use basis using a personal application service provider
an application service provider (ASP) supplies software applications (and often related services, such as maintenance, technical
support, information storage, and the like) over the Internet that would otherwise reside on customers’ computers
Physiological Interaction
Automatic Speech Recognition (ASR)
an ASR system not only captures spoken words but also distinguishes word groupings to form sentences
to perform this, an ASR system follows 3 steps:
1) Feature analysis—The system captures your words as you speak into a microphone, eliminates any background noise, and
converts the digital signals of your speech into phonemes (syllables).
2) Pattern classification—The system matches spoken phonemes to a phoneme sequence stored in an acoustic model database.
3) Language processing—The system attempts to make sense of what you’re saying by comparing the word phonemes
generated in step 2 with a language model database.
Summary: Student Learning Outcomes Revisited
1. Describe the emerging trends and technologies that will have an impact on the changing Internet.
Emerging trends and technologies that will have an impact on the changing Internet include
Software-as-as-service (SaaS)—delivery model for software in which you pay for software on a pay-per-use basis instead
of buying the software outright.
Push—technology environment in which businesses and organizations come you via technology with information, services,
and product offerings based on your profile.
F2b2C (factory-to-business-to-consumer)—an e-commerce business model in which a consumer communicates through a
business on the Internet and directly provides product specifications to a factory that makes the customized and
personalized product to the consumer’s specifications and then ships it directly to the consumer.
VoIP (Voice over Internet Protocol)—allows you to send voice communications over the Internet and avoid the toll charges
that you would normally receive from your long distance carrier.
Web 2.0—second generation of the Web focusing on on-line collaboration, users as both creators and modifiers of content,
dynamic and customized information feeds, and many other services.
2. Define the various types of technologies that are emerging as we move toward physiological interactions with technology.
Emerging technologies in the area of physiological interaction include
Automatic speech recognition (ASR)—a system that not only captures spoken words but also distinguishes word groupings
to form sentences.
Virtual reality—three-dimensional computer simulation in which you actively and physically participate.
CAVE (cave automatic virtual environment)—special 3-D virtual reality room that can display images of other people and
objects located in other CAVEs all over the world.
Haptic interface—uses technology to add sense of touch to environment that before had only visual and textual elements.
Biometrics—use of physiological characteristics—such as your fingerprint, the blood vessels in the iris of your eye, the
sound of your voice, or perhaps even your breath—to provide identification.
3. Define the emerging trends of near field communication, Bluetooth, WiFi, cell phones, and RFID, as they relate to the
wireless environment.
Emerging trends related to the wireless environment include
Near field communication (NFC)—short-range wireless technology developed mainly for use in mobile phones.
Bluetooth—standard for transmitting info in the form of short-range radio waves over distances of up to 30 feet.
WiFi—standard for transmitting information in the form of radio waves over distances up to about several miles.
Cell phones—advances in storage capacity, processor capability, music enhancements, and video support—and threats
such as viruses and hackers.
RFID (radio frequency identification)—the use of a chip or label to store information, by which information is transmitted
from, or written to, the tag or label when the chip is exposed to the correct frequency of radio waves.
4. Define and describe emerging technologies that, while purely technology, can and will impact the future.
These technologies include
