  • 3. MAPS are universal medium for communication, easily understoodand appreciated by most people, regardless of language or culture.•oldest forms of nonverbal communication. DIGITAL WORLD• Navigational• Informational• Transactional PHYSICAL WORLD• We use properties and characteristics of objects and places to locate anddifferentiate them among other objects and environment in the real world. Ex: ATM cards Dept of ISE SDMCET 2009-10 3
  • 4. TaPuMa is a digital, tangible public map that allows people to usetheir own belongings or the everyday objects they carry with themto access relevant informationFEATURESPhysical objects as key words.Locations and non-spatial information.Multiple user interaction.Dynamic and contextual information.

  • 7. Table-top environment where map and dynamic content is projected on the table. Dept of ISE SDMCET 2009-10 7
  • 8. A camera mounted above the table identifies and tracks the locations of the objects on the surface.Dept of ISE SDMCET 2009-10 8
  • 9. The projector augments the table and objects on the table with projected digital information from overhead along with the map. Dept of ISE SDMCET 2009-10 9
  • 10. The projector and the camera are connected to a computer. A software program identifies and registers the location of objects on the table. On the basis of identifications of the objects, the software program provides relevant information visualization to be shown on the tableDept of ISE SDMCET 2009-10 10
  • 11. The system also consist supplementary components such asRFID readers to support the user identification and providecustomized information relevant to the user.For example : A student ID card. Dept of ISE SDMCET 2009-10 11
  • 12. •Working prototype consists of a Sensetable, a projector and a laptop computer. •Sensetable detects IDs and positions of circuit-embedded small plastic packs(tokens) on a table. •The Sensetable is connected to the computer.Dept of ISE SDMCET 2009-10 12
  • 13. • Sensetable program which is running on the computer generates and updates an xml file. •This xml file describes the positions of each packs on it. •The xml file is loaded by another program that is made using Adobe Flash.Dept of ISE SDMCET 2009-10 13
  • 14. • The flash program scans and uses the location of the tokens to generate relevant visualization. •The projector then projects the graphics on the Sensetable.Dept of ISE SDMCET 2009-10 14
  • 15. For Example: TaPuMa shows the position and path to the gate when the boarding pass is placed on the surface of TaPuMa.Dept of ISE SDMCET 2009-10 15
  • 16. New prototype we use OpenCV, an open source computer visionlibrary originally developed by Intel, to detect objects on the surface ofthe table. The openCV software uses computer vision techniques for thedetection and tracking of the objects. The software has access to images of a predefined set of objects. Besides this, the system will also be capable to detect everyday objectslike coffee cups, keys, mobile phones. Also exploring the possibilities of using user-defined objects, so thatTaPuMa can learn from users about new objects and their relations to theuser intentions. Dept of ISE SDMCET 2009-10 16
  • 17. Eliminates the language barrier of conventional graphicalinterfaces. Enables multiple user interactions. Requires a very little learning. TaPuMa provides the ability to show dynamic andcontextual information. Allows people use the objects they carry around as hints. Dept of ISE SDMCET 2009-10 17
  • 18. This technology is still not mature and foolproof. User is not carrying objects which is a hint to theinformation he is interested in. Impossible to map all the possible information we seek forto our objects. Objects as keywords can also be ambiguous. Different places, age-group, and culture have differentmeanings to objects. Dept of ISE SDMCET 2009-10 18
  • 19. With TaPuMa, maps in the places like airports,shopping malls, movie theaters, where people usuallycarry similar objects with them, are less challengingthan generic public maps in a city or town. Dept of ISE SDMCET 2009-10 19
  • 20. Object Amelioration Dept of ISE SDMCET 2009-10 20
  • 21. We think maps will exist as long as humanexistence continues; everyday objects as well. Proposes a novel interaction mechanismwhere physical objects are used as interfacesto digital information. TaPuMa is an attempt to bridge the gapbetween our physical and informationalworlds.
