  2. 2. MOBILE COMPUTING <ul><li>   INTRODUCTION </li></ul>MOBILE COMPUTING is a generic term describing your ability to use technology to wirelessly connect to and use centrally located information.
  3. 3. Two categories <ul><li>Portable computing </li></ul><ul><li>mobility computing </li></ul><ul><li>Portable computing actually refers to wired communication. Moveable for small area. </li></ul><ul><li>Mobility computing is true wireless communication. Movable ,Accessed from anywhere. </li></ul>
  4. 5. USAGE OF MOBILE COMPUTING <ul><li>First used in vehices . </li></ul><ul><li>Cell phones are another rampant proliferation of mobile computing today. </li></ul><ul><li>Every single cell phone is a computer in its own right. </li></ul><ul><li>Blue tooth and MMS has brought cell phone users closer . </li></ul>
  5. 6. ADVANTAGE OF MOBILE COMPUTING: <ul><li>In built wireless capabilities </li></ul><ul><li>One of the primary reasons is cost. </li></ul><ul><li>wireless capacity is so inexpensive </li></ul>
  6. 7. Optimized interactive images and graphics for the wireless web
  7. 8. Mobile Image software: <ul><li>Automatically optimizes the image. </li></ul><ul><li>This software uses 'Just-In-Time' image delivery. </li></ul><ul><li>Uses proprietary data streaming and caching technology to serve the images. </li></ul><ul><li>Provides scalability -- capable of supporting thousands of simultaneous users. </li></ul><ul><li>Maps overlaid with information on traffic . </li></ul>
  8. 9. Mobile Image software: <ul><li>Real time stock charts with links to news and buy/sell functions . </li></ul><ul><li>Photographs of products /Drawings of floor plans for purchasing Real Estate. </li></ul><ul><li>It can be used for Peer-to-Peer applications like the exchange of &quot;photo“. </li></ul>
  9. 10. Riding the Wireless Internet Revolution <ul><li>The number of Internet users over wireless links is expected to grow from 4 million today to over 58 million by the year 2006. </li></ul><ul><li>In the U.S. there will be 21.3 million mobile data users by the end of 2001. </li></ul><ul><li>In Japan, DoCoMo is adding roughly 1 million wireless Internet subscribers for each month. </li></ul>
  10. 11. Image Engine Framework
  11. 12. <ul><li>A given image is processed and represented as child Image objects using an ImageLOD data model. </li></ul><ul><li>Imagetranscoding and adaptation. </li></ul><ul><li>Working on different protocols - HTML, HDML, WAP, Palm OS, Pocket PC,etc. </li></ul><ul><li>Working on different network technologies – CDMA, CDPD, GSM, etc. </li></ul><ul><li>Capable of handling different image/graphic file formats - JPEG, GIF, PNG, WBMP, BMP, etc. </li></ul>
  12. 14. Translation: <ul><li>The translation methods convert the image objects to different formats, sizes, color depth, compression and scale. </li></ul><ul><li>The slicer methods generate different hierarchical sections of the original image. </li></ul><ul><li>Both this methods can be cascaded to change the fidelity of the images. </li></ul>
  13. 15. Architecture <ul><li>Administration Console: provides the ability to control device and user profiles. </li></ul><ul><li>ImageLOD Representation </li></ul><ul><li>Content Analysis: Analyze the inter-relationship between different sections of the content. </li></ul><ul><li>Transformation: progressive image representation with color depth, scaling factor. </li></ul>
  14. 16. <ul><li>Content Customization: These modules customize the content based on the user interests. </li></ul><ul><li>The architecture is based on a Proxy or Network Server paradigm. </li></ul><ul><li>A set of JavaBeans, which provides the most flexible configuration. </li></ul>
  15. 18. Advantage of image engine: <ul><li>Image Engine propels businesses to the second wave of the Internet . </li></ul><ul><li>Image Engine helps make accessing content across the Wireless Internet quicker, easier , delivering only what you need. </li></ul><ul><li>Image Engine helps make communication across the Wireless Internet more targeted, convenient and personalized. </li></ul>
  16. 19. CONCLUSION: <ul><li>By bringing together powerful image handling capabilities into a robust and versatile standards-neutral architecture, the Image Engine imaging application platform is intended to help propel business possibilities to a whole new level of experiences in the pervasive computing environment. </li></ul>
