Why an online conference?

The Where Online Conference provides an ongoing forum for exploring the latest issues, without the expense or inconvenience of travel. It's our way of bringing Where to your desktop and keeping the conversation alive throughout the year.

How does it work?

In an online conference, participants log on and attend sessions, enter into discussions with other participants and presenters using the live text chat, and are able to pose questions and interact with people from all over the world. It has a similar structure to a physical conference, except that you hear the speakers discuss topics and watch their slide presentations via your computer from the convenience of your office or home. You'll take breaks between sessions and enjoy lively conversations with your fellow attendees.

Where 2.0 Online Conference has concluded

The mobile phone is fast becoming the primary I/O device for geodata. Since the last Where 2.0 Conference in May 2009, the iPhone has continued to define the state of the art for location enabled sensors. By creating a widespread platform that allows for third-party development and geolocation, iPhones are advancing the whole industry. What game-changing applications are now under construction? The combination of camera, GPS, accelerometer, and compass on a single device now allows us to layer information on top of the world. How are we perceiving and consuming new information? How can the layers be edited to push the envelope further? Learn more as the first Where 2.0 Online Conference explores:

The O'Reilly Where 2.0 Online Conference is the meeting ground where emerging trends are examined, predictions are made, and business models vetted. In this half-day online conference, you'll log on and attend sessions by viewing slides and listening to the speakers presentation. You'll be able to pose questions and interact with people from all over the world using live text chat. You will have the opportunity to hear from experts, share your ideas, ask questions, and join in a conversation with panelists and other participants, all looking to build a solid and profitable future for location enabled technologies.



US-PST: 9:00am - 9:15am
US-EST: 12:00pm - 12:15pm

The Sensors in Your iPhone + Q&A

US-PST: 9:15am - 10:05am
US-EST: 12:15pm - 1:05pm

The iPhone, like a lot of high-end smart phones these days, comes with a number of sensors: camera, accelerometer, GPS, proximity, magnetometer (digital compass). The first half of this session will cover the parameters and functions for each sensor. The second half will be a live coding of an accelerometer based app. We'll be demonstrating the use of iSimulate as a tool to capture your iPhone's movement. Each section will also have an equal amount of Q&A time. This hour long section will be the foundation for the rest of the event and is based on the Using Sensors chapter of Alasdair's upcoming book Learning iPhone Programming. Participants will receive an advance copy of this chapter as a part of the conference.

Speaker: Alasdair Allan, University of Exeter and Babilim Light Industries


US-PST: 10:05am - 10:20am
US-EST: 1:05pm - 1:20pm

Augmented Reality + Q&A

US-PST: 10:20am - 10:50am
US-EST: 1:20pm - 1:50pm

Having a compass and camera built into the iPhone opens up possibilities for augmented reality (AR) on the iPhone. Programmers now know more than just location; by also knowing which direction the phone is facing, you can overlay objects on users’ view of the world. Derek Smith of SimpleGeo is a developer of their AR framework. He’s going to step you through the challenges of providing a realtime overlay on the physical world. Nicola Radacher of Mobilizy will discuss what they’ve learned in the four releases of their popular Wikitude.

Speaker: Derek Smith, SimpleGeo and Nicola Radacher, Mobilizy

Location Sensors + Q&A

US-PST: 10:50am - 11:30am
US-EST: 1:50pm - 2:30pm

The iPhone includes several ways to determine your location: cellular tower triangulation, Wi-Fi-based positioning using Skyhook Wireless’s system, and GPS. The iPhone SDK gives programmers the ability to add location capabilities to their apps using the Core Location framework. Alok Deshpande from Loopt, will discuss what they learned about building location-aware apps. Alok will be followed by Nick Brachet of Skyhook Wireless, who will give an overview of the Skyhook system and how it uses WiFi to provide location to applications.

Speaker: Alok Deshpande, Loopt and Nick Brachet, Skyhook Wireless

Working with Audio Input + Q&A

US-PST: 11:30am - 12:00pm
US-EST: 2:30pm - 3:00pm

The microphone is useful for more than just transmitting and recording audio; it's a sensor in its own right, and can be used to create applications that react to things around you. Martin Roth from RjDj will talk about how they used the microphone to connect the experience of listening to music with the world around the user.

Speaker: Martin Roth, RJDJ


US-PST: 12:00pm - 12:15pm
US-EST: 3:00pm - 3:15pm

Computer Vision and the iPhone Camera + Q&A

US-PST: 12:15pm - 12:45pm
US-EST: 3:15pm - 3:45pm

The camera and associated APIs on the iPhone are easy to get started with, but it is tricky to unlock the full potential. iPhone OS 3.1’s new camera APIs open the door for much more innovative uses of the camera, such as programmatic picture capture and completely customizable interfaces. With techniques from computer vision, the iPhone camera can be made to recognize things in the real world. Even with the enhancements in OS 3.1, the iPhone SDK still prevents realtime video processing, a killer application area for mobile cameras. Occipital co-Founder Jeffrey Powers discusses getting started with the camera, and then will dive into advanced tricks that Occipital uses for photo capture in Snapture and for barcode recognition in RedLaser.

Speaker: Jeffrey Powers, Occipital

Program subject to refinement.

The entire conference will be recorded and made available to attendees free of charge afterwards.
