CROWDSOURCING Crowdsourcing is, according to the Merriam- Webster Dictionary, the practice of obtaining needed services, ideas, or content by soliciting contributions from a large group of people, and especially from an online community, rather than from traditional employees or suppliers.

  21. 21. HOW TO PROVIDE UPDATES TO OLD DATA IN STREET VIEW?
  22. 22. MAIN CONTRIBUTION
  23. 23. 1. From a large number of users playing the game, researcher expect to collect up-to-date information about the street view and consumers will be provided with more accurate information. 2. In addition, based on the differences identified, the game can also be used by service providers to note which areas have changed the most and provide guidance on which areas need to have the street view images collected again.

  25. 25. HIDDEN VIEW GAME A human computation game was designed for users to identify differences between a stored image and the current real world
  26. 26. BASED ON SIMILAR PRINCIPLES TO THE “HIDDEN CATCH” GAME
  27. 27. HOW TO PLAY The user is given a and the goal of the game is to identify whether a label (or icon) exists or not in the latest street view. The user is shown an and is expected to drag the icon to the appropriate location on the street view and confirm the chosen location by selecting the ; if the icon does not exist in that particular street view, then the user selects In order to keep the game simple and entertaining, the following were added street view image icon checkmark ‘X’ three features

  31. 31. HIGH-LEVEL BLOCK DIAGRAM
  32. 32. THE OUTPUT OF THE GAME
  33. 33. SCORE As users play the game, the database will be updated with a score that represents the accuracy of the labels. There are two significant challenges in the Hidden View game: 1. can the user selection be trusted? (i.e. user credibility) and 2. how accurate are the labels that are currently in the database? (i.e. label accuracy).
  34. 34. ALGORITHM A simple probabilistic approach is used to design the algorithm that predicts the user accuracy and the label scores; it is based on the following relationships: label_score = f (label_score, user_credibility, selection) user_credibility = g (label_score, user_credibility, selection)
  35. 35. EVALUATION
  36. 36. IMPLEMENTATION In the initial implementation, all icons that were obtained from the Google Place API were given an initial score of 0.6 and the randomly generated icons were given an initial score 0.4. A user study was performed and had two goals: 1. to obtain feedback on the user interface of the game and 2. to determine whether meaningful information could be collected.
  37. 37. EXPERIMENTS There were 17 participants who were familiar what the location of the street view used in the game Each user played the Hidden View game three times Each game consisted of 25 street view images that covered approximately 300m of streets The street view images were sourced from Daum Road View, and the images were taken from May 2011.
  38. 38. RESULT
  39. 39. DEVELOPMENT OF RESEARCH IDEAS
  40. 40. RESEARCHER They plan on expanding the game to include additional entertainment features so that it will attract more users. In addition to the commonly used POIs, we plan on expanding the icons to non-traditional POIs, such as construction icons, which could provide valuable information to drivers.
  41. 41. REVIEWER Adding GPS feature to more accurate information when updating Use this game to update WA & WB map and update the sampling frame for census and survey Developing method to create shortcut way to avoid traffic jam
  42. 42. CONCLUSION
  43. 43. In this work, an initial implementation of the Hidden View game was presented; this game provides an opportunity to obtain the latest information of a street view through a crowdsourced game.
