©2003 The McGraw-Hill Companies 11.1 Computers and Their Interfaces Fundamentally change the technology itself Change the way you interface or interact with your computer Most visible emerging technologies are those that:

©2003 The McGraw-Hill Companies 11.1 Computers and Their Interfaces Future forms of interaction –Automatic speech recognition –3-D technologies –Biometrics –Wearable computers –Multi-state CPUs –Holographic storage devices –Thought-control user interfaces

©2003 The McGraw-Hill Companies ASR Today and Tomorrow ASR is already available Will become more widespread Issues: –ASR must be flexible to recognize the voices of many people –Some systems are limited in recognizing continuous speech patterns –Speech not yet understood within the context of a conversation

©2003 The McGraw-Hill Companies Automatic Speech Recognition Captures your speech Distinguishes your words and word groupings to form sentences Includes these IT components: –Microphone & sound card –Software to distinguish your words –Database that contains words & language rules

©2003 The McGraw-Hill Companies Automatic Speech Recognition An ASR system processes speech in three steps: 2. Pattern Classification 1. Feature Analysis 3. Language Processing

©2003 The McGraw-Hill Companies Automatic Speech Recognition 1.Feature analysis –Captures words –Converts digital signal of voice into phonemes 2.Pattern classification –Attempts to recognize phoneme –Finds match in acoustic model database 3.Language processing (Key step) –Attempts to make sense of what you're saying by comparing the possible word phonemes to rules in a language model database

©2003 The McGraw-Hill Companies 3-D Two-dimensional presentations of information show only length and width. Pseudo three-dimensional presentations of information incorporate shadowing to show depth.

©2003 The McGraw-Hill Companies Real 3-D Can see depth of an image Can turn image to reflect different angles & perspectives Already available on some Web sites Real 3-D is becoming more popular –Limited by computer speed and capacity –Newer and cheaper computers will make real 3-D more available

©2003 The McGraw-Hill Companies Multi-state CPUs CPUs and Storage Devices What Can You Expect to See? Multi-state CPUs work with information represented in more than just two states,probably ten states with each state representing a digit between 0 and 9 Holographic storage devices will store information on a storage medium that is composed of 3-D crystal-like objects with many sides and faces. On each face information can be stored Holographic storage devices

©2003 The McGraw-Hill Companies Holographic Storage Devices

©2003 The McGraw-Hill Companies Thought-Control User Interfaces Graphical user interfaces will change to voice- control user interfaces through automatic speech recognition With Mind Drive technology a small sensing device on a finger captures 70 different bio- electrical signals produced by the mind that radiate though-out the body. These are processed and interpreted to determine what a person is thinking

©2003 The McGraw-Hill Companies Whats Your Thoughts on These Emerging Technologies? Are you fast at typing or would you rather use speech recognition? Can you ever foresee a time when your computer will capture your thoughts? Is technology becoming so important that you need to wear it all the time like a regular piece of clothing? Do you want an Internet-enabled toilet monitoring your physical well-being?

©2003 The McGraw-Hill Companies 11.2 The Changing Internet Internet-based trends and Internet-enabled technologies Internet-enabled home True personalization Renting software from ASPs E-cash

©2003 The McGraw-Hill Companies E-Cash Electronic representation of cash Can buy products on the Web by sending the e-cash file to a merchant Far beyond digital money & wallets

©2003 The McGraw-Hill Companies Using E-Cash on the Web E-Cash Transaction p Fig

©2003 The McGraw-Hill Companies What's Holding Up E-Cash? Anyone can be an electronic bank There are no e-cash standards Merchants must have accounts with electronic banks E-cash makes money laundering easy E-cash is easy to lose, impossible to replace Biggest Drawback: Acceptance by the consumer market at large that e-cash is safe to use

©2003 The McGraw-Hill Companies Renting Software from Application Service Providers Many companies are already planning for "pay-for-use" software over the Web May not need a disk drive in the future – even for Web- oriented devices p Fig

©2003 The McGraw-Hill Companies Personalization When a business knows so much about you that it can anticipate what you want or need and offer it to you This isnt spam You will receive personalized offerings that no one else will receive May be achieved with global positioning system (GPS) technology

©2003 The McGraw-Hill Companies Personalization or Spam? If your cell phone is GPS-enabled, can any organization track your movements? Is a push environment always better than a pull environment or will we need a combination of the two?

©2003 The McGraw-Hill Companies Push (Not Pull) Technologies

Numerous digital camera/projection units capture you both, send the images to the opposite CAVEs, and re-create your 3-D likenesses
