Signpost 2007

Signpost2007 is a location aware conference guide. It lets the user browse a conference's or event's schedule, shows the user where on the map each sessions is held and tells the user how to get there from his/her current location. Signpost2007 uses well established AR tracking technology (Studierstube Tracker) for sparse wide area indoor tracking.

Signpost2007 has 4 screens which each represent a different tool set of the application.

Schedule

On the Schedule screen, the user can filter via days and track titles to quickly browse even large lists of talks. After selection a specific talk, the screen switches to the map view that shows the user his/her current and the talk's location. Furthermore a full text search engine allows finding any task or author.

   

Map

On the Map screen, the user can pan and zoom the 2D map freely to explore the conference location. Signpost2007 renders the map with sub-pixel accuracy (bilinear filtering, a feature usually only implemented in hardware) in software at high frame rates even on slow devices.

Since the TechEd edition of Signpost2007, multiple maps are supported that can be switched at any time. Furthermore we added a 3D rendering of the building that shows the current 2D and target positions.

   

   

Tracked

The Tracked screen has three functions: In 2D mode it shows the users his/her current live-tracked position and direction on the 2D map, while it automatically positions and orients (rotates) the map correctly. In the 3D mode ir rotates the building, showing the user which direction he's facing. In the Augmented Reality (AR) mode it transforms the device into a magic lens that lets the user view Augmented Reality objects that might be bound to certain markers (read more about this in the "treasure hunt" section below).

   

Tool

The Tool screen allows updating the schedule via wireless networking. Conference organizers can provide schedule updates via RSS feeds. Finally, the user can use the camera setup wizard to tweek camera settings and thereby overcome bugs in DirectShow drivers.

 

Treasure Hunt Game

For an even greater fun of using Signpost2007 there's also a built-in treasure hunt game. Conference or event organizers can announce prices for those users who find all hidden virtual items. Those virtual items can either be the letters or of the conference organizer's name or any other 3D objects.

Handheld Augmented Reality at commercial Quality

Signpost2007 is the first application developed in the Handheld AR project that targets a large public audience. It goes beyond the usual research demonstration application, but was instead designed from ground up with commercial product quality in mind. It was specifically ported and tested to a wide range of devices, including:

  • Tornado Noble
    also known as: i-mate SP5, O2 XDA IQ, O2 XDA Orion, Vodafone VDA II, Vodafone v1240, Qtek 8310, Dopod 577W
  • Palm Treo 700W
  • MotorolaQ
  • HTC Excalibur
    also known as: Orange SPV E600, T-Mobile MDA Mail, T-Mobile Dash, Dopod C720W, O2 XDA Cosmo, HTC S620
  • HTC Wizard
    T-Mobile MDA Vario, T-Mobile MDA US, Dopod 838, Vodafone VPA Compact II, Cingular 8125, Cingular 8100, O2 XDA mini PRO, O2 XDA mini S, Qtek 9100, Orange SPV M3000, I-Mate K-JAM
  • HTC Startrek
    also known as: Orange SPV F600, Cingular 3125, Qtek 8500, I-Mate Smartflip, Dopod 710 / StrTrk S300
  • HTC Artemis
    also known as: Orange M650, O2 XDA Orbit, Dopod P800W, T-Mobile MDA Compact III, HTC P3300
  • HTC Vox
    also known as: Vodafone VDA V, Dopod C500, HTC S710, Orange SPV E650

Signpost2007 is built on top of Studierstube ES, using Studierstube Tracker for pose tracking and a custom, high speed and high quality map rendering algorithm. While performance is not a top priority for such an application we measured frame-rates of at least 10 fps on even the slowest supported devices.

Video Download

A video demonstrating the Signpost2007 MEDC Edition can be downloaded from here. Please notice that many features described above were added for the TechEd Edition and are not shown in the video. A video of the current version will be available here soon.

The video is 23.7 MBytes large, has a resolution of 720x576 at 25Hz and is encoded with DivX 6 (which can be downloaded from here). A smaller version of the same video with a resolution of 512x400 pixels and a size of 9.5MB can be downloaded from here.

Introduced at MEDC2007

Signpost2007 has been introduced to a public audience in May 2007 at the MEDC (Microsoft Mobile & Embedded Developers Conference) 2007 in Las Vegas. It is planned to deploy Signpost2007 on further Microsoft conferences (to be announced).

Deployed at Tech-Ed 2007

We created a heavily extended version of Signpost2007 for the Microsoft Tech-Ed conference 2007 in Orlando.
