This concept of Layar Vision layer associates some geo-data (POIs) with logos of companies. It answers the following questions: how to get nearby devices (places) with the same logo. E.g. each ATM has got bank’s logo. So, it is just a practical case - for any ATM that does not work for example we can find the nearby places with ATMs from the same bank.

Search by logo

  1. 1. Search by logos use case for Layar Vision Dmitry Namiot dnamiot@gmail.com Lomonosov Moscow State University
  2. 2. Introduction <ul><li>Our conception shortly: </li></ul><ul><li>Search nearby things (places) with the same logo we can recognize via Layar Vision </li></ul>
  3. 3. Example <ul><li>Here is a typical ATM </li></ul>
  4. 4. Example (cont.) <ul><li>Each ATM has got bank’s logo </li></ul>
  5. 5. Example (cont.) <ul><li>Suppose you see ATM that does not work: </li></ul>
  6. 6. Model <ul><li>How to find more ATMs for the same bank nearby? </li></ul><ul><li>Visual geo search – let us use bank’s logo as a key for search </li></ul><ul><li>Each search is a typical geo-layer. We just need to know logo (name) for getting to the proper geo-layer </li></ul>
  7. 7. Model <ul><li>Layar Vision enabled layer is a wrapper for several geo-layers </li></ul><ul><li>As soon as the logo is recognized by Layar Vision we can switch to the “standard” geo-layer for this bank </li></ul><ul><li>That switch could be performed manually (as an action for the Layar Vision enabled layer response) or simply via auto-trigger (we do not need some special response from Layar Vision enabled layer at all) </li></ul>
  8. 8. The steps are: <ul><li>Collect logos (two Russian banks in this example) </li></ul><ul><li>Upload them to Layar in order to train Layar Vision recognize them </li></ul><ul><li>Create “standard” geo-location layer for the each brand (each logo). </li></ul><ul><li>Invoke (open) geo-layer in action defined for vision enabled layer </li></ul>
  9. 9. How does it work <ul><li>Vision enabled layer here is actually just a placeholder for geo-layers </li></ul><ul><li>Vision enabled layer can either display the recognized logo + action for switching to the appropriate geo-layer </li></ul><ul><li>OR </li></ul><ul><li>Vision enabled layer can define auto-trigger for geo-layer associated with the recognized logo </li></ul>
  10. 10. Technical details <ul><li>We can use one endpoint for all supported requests </li></ul><ul><li>By default server side script returns data for vision enabled layer </li></ul><ul><li>In the parameterized requests it returns POIs for geo-layers </li></ul>
  11. 11. Conclusion <ul><li>Visual geo search – go the AR layer after getting the logo recognized </li></ul><ul><li>This concept demonstrates search for ATMs by bank’s logo </li></ul><ul><li>Could be extended of course to any logo (logos) </li></ul><ul><li>Analogue: logo here replaces QR-code with landing to search page </li></ul>
