Summary Conductor allows for multi-device usage by broadcasting cues to all devices in a group. Cues can be clicked to open the information on the most appropriate application or dragged across the screen to a list of possible functions to be performed with this cue. This generates a Duet between two devices, so any change in one device reflects on the other.
Description Hamilton and Wigdor describe the Conductor system, which relies on cues and duets to facilitate functionality chaining across devices. A user can choose to broadcast a cue from a menu on the source device, which then triggers a special cue widget to be shown on the potentially receiving devices. Cues are displayed chronologically and can be hidden if left untouched. Tapping a cue will trigger the most appropriate action, for example launching an email application if the cue was related to broadcasting an email message. Duets are an extension of Cues and facilitate functionality bonding across devices. Duets are formed among currently running applications and can be terminated by quitting the application. Forming Duets is achieved by dragging a Cue from the left side of the screen to the right side to a list of Duets, which is a visual representation of the functionality chaining that can be formed between devices. Adding devices to a group that can be actively used, called a symphony, is achieved by scanning QR-Codes on other devices that need to be added to the group, touching or bumping devices, or by using a proxy for a device positioned out of reach. Such a proxy can be a QR-Code or an NFC tag placed nearby.
