There has been a massive growth in the number of people who film and upload amateur footage of events to services such as Facebook and Youtube, or even stream live to services such as LiveStream. We present an exploratory study that investigates the potential of these spectators in creating footage en masse; in this case, during a live trial at a local marathon. We deployed a prototype app, RunSpotRun, as a technology probe to see what kinds of footage spectators would produce. We present an analysis of this footage in terms of its coverage, quality, and contents, and also discuss the implications for a) spectators enjoying the race, and b) extracting the stories of individual runners throughout the race. We conclude with a discussion of the challenges that remain for deploying such technology at a larger scale.

We present MultiNet, a novel method for securely associating devices with a domestic wireless network. We show that MultiNet has usability benefits over currently deployed commercial solutions while being backwards compatible with existing devices. MultiNet reduces the interaction overhead of secure association by focusing on users' interactions rather than the network's requirements. This leads to a novel architectural arrangement of the home network infrastructure: the network is dynamically re-configured to accept each pre-configured device, rather than the current norm where each device is configured to be acceptable to the pre-configured network. Assuming devices are pre-configured for a unique, device-specific network name and passphrase, MultiNet constructs an out-of-band visual channel via an intermediary network controller device to convey the device's configuration to the network. This makes the interaction to join a device to the wireless network lightweight and identical across all devices, considerably reducing the interaction overheads for users.

This demo presents MultiNet, a novel method for joining devices to a domestic Wi-Fi network. MultiNet dynamically reconfigures the network to accept each device, rather than configuring each device to fit the network as is the norm. It does so by assuming that each device is pre-configured with a cryptographically generated WPA2 network SSID/passphrase pair, and then providing a lightweight interaction through which the user creates a new network for each device. This approach makes securely adding devices to a wireless network straightforward without compromising security or burdening the user, and maintaining backward compatibility with existing deployed standards and protocols.
