  1. 1. Chapter 17 Inventing The Future
  2. 2. Topics <ul><li>Tomorrow Never Knows </li></ul><ul><li>From Research to Reality: 21st-Century Information Technology </li></ul><ul><li>Human Questions for a Computer Age </li></ul>“ The best way to predict the future is to invent it.” Alan Kay
  3. 3. Tomorrow Never Knows <ul><li>Technology is hard to foresee, and it is even harder to predict the impact that technology will have on society. </li></ul>The 1930 movie Just Imagine presented a bold, if not quite accurate, vision of the future; here Maureen O’Sullivan sits in her personal flying machine.
  4. 4. Tomorrow Never Knows <ul><li>We can predict the future by recognizing the four phases of any technology or media business: hardware, software, service, and way of life. </li></ul>
  5. 5. Tomorrow Never Knows <ul><li>Hardware--develop new hardware </li></ul><ul><li>Software--software such as television programs, web pages and databases give value to hardware products </li></ul><ul><li>Service--companies focus on serving their customers </li></ul><ul><li>Way of life--product/service becomes so entrenched that it becomes almost invisible </li></ul>
  6. 6. From Research to Reality <ul><li>Ideas are sprouting from the minds of engineers and scientists that will collectively shape the future of information technology. </li></ul><ul><li>Trends point to those ideas most likely to succeed. </li></ul>
  7. 7. Tomorrow’s Hardware: Trends and Innovations <ul><li>Speed: computer speed today typically is measured in MIPS (millions of instructions per second), where an instruction is the most primitive operation performed by the processor </li></ul><ul><li>Size: central components of a modern computer are stored on a handful of tiny chips </li></ul><ul><li>Efficiency: desktop & portable computers consume very little electricity </li></ul>The IBM S/390 G6 server performs up to 1.6 billion instructions per second—almost 1 billion times the performance of the historic Mark I—at a cost that is far less than a mainframe or supercomputer.
  8. 8. Tomorrow’s Hardware: More Trends and Innovations <ul><li>Capacity: optical, magnetic, and semiconductor storage devices virtually eliminate storage as an issue </li></ul><ul><li>Cost: hardware has dramatically dropped in cost </li></ul>
  9. 9. Technological Innovations <ul><li>Alternative chip technologies </li></ul><ul><li>Alternative architectures </li></ul><ul><li>Alternative storage technologies </li></ul><ul><li>Alternative output displays </li></ul><ul><li>Alternative input devices: sensors </li></ul>“ Smart dust” computers at the University of California at Berkeley help monitor and control heating and cooling systems using environmental sensors and wireless communication links
  10. 10. Tomorrow’s Software: Evolving Applications and Interfaces <ul><li>Computer scientists aren’t even close to developing tools that will allow programmers to produce error-free software quickly. However, software technology is advancing rapidly. </li></ul><ul><ul><li>WIMP : (windows, icons, menus, and pointing devices) interface is easier to learn and use than earlier character-based interfaces </li></ul></ul><ul><ul><li>SILK : for speech, image, language, and knowledge capabilities. </li></ul></ul>
  11. 11. Evolving Interfaces <ul><li>SILK incorporates many important software technologies: </li></ul><ul><ul><li>Speech and language: voice recognition systems, natural-language processing </li></ul></ul><ul><ul><li>Image: three-dimensional models, animation, and video clips; virtual reality interfaces </li></ul></ul><ul><ul><li>Knowledge: self-maintaining systems </li></ul></ul>
  12. 12. Tomorrow’s Service: Truly Intelligent Agents <ul><li>Agents are software programs designed to be managed rather than manipulated. </li></ul><ul><li>An intelligent software agent: </li></ul><ul><ul><li>asks questions as well as responds to commands </li></ul></ul><ul><ul><li>pays attention to its user’s work patterns </li></ul></ul><ul><ul><li>serves as a guide and a coach </li></ul></ul><ul><ul><li>takes on its owner’s goals </li></ul></ul><ul><ul><li>uses reasoning to fabricate goals of its own </li></ul></ul>
  13. 13. More on Intelligent Agents <ul><li>Wizards and other agent-like software: guide users through complex tasks and answer questions when problems arise </li></ul><ul><li>Bots: software robots that crawl around the Web collecting information, helping consumers make decisions, answering email, and even playing games </li></ul>
  14. 14. Future Software Agents <ul><li>A well-trained software agent in the future might accomplish these tasks: </li></ul><ul><ul><li>Remind you that it’s time to get the tires rotated on your car </li></ul></ul><ul><ul><li>Distribute notes to the other members of your study group </li></ul></ul><ul><ul><li>Manage your appointments and keep track of your communications </li></ul></ul><ul><ul><li>Defend your system and your home from viruses, intruders, and other security breaches </li></ul></ul><ul><ul><li>Detect your emotional state and respond accordingly </li></ul></ul>
  15. 15. Tomorrow’s Way of Life: Transparent Technology “ This will be the generation where the technology disappears into the tool, serving valuable functions but keeping out of the way – the generation of the invisible computer.” Donald A. Norman
  16. 16. Embedded Intelligence <ul><li>Computers are disappearing into more of our tools. </li></ul><ul><li>Information appliances, including cell phones, fax machines, and GPS devices, perform their specialized functions while hiding the technological details from their users. </li></ul>
  17. 17. Embedded Intelligence <ul><li>Wearable computers : strap-on units for active information gatherer </li></ul><ul><li>CPUs, keyboards, and touchpads stitched right into the clothes, turning their wearers into wireless Internet nodes </li></ul>
  18. 18. Ubiquitous Computers <ul><li>Examples of ubiquitous computers are smart badges and smartboards </li></ul><ul><li>While ubiquitous computers offer convenience and efficiency beyond anything that’s come before, they also raise serious questions about personal privacy, intimacy, and independence. </li></ul>
  19. 19. From Internet to Omninet <ul><li>Connectivity is a critical part of ubiquitous computing. </li></ul><ul><li>As more machines become connected, the Net will evolve from today’s loose digital fishnet into a tightly-woven, seamless fabric that surrounds us. </li></ul>
