MultiFi : multi-fidelity interaction with displays on and around the body

This work was supported by the EU FP7 project MAGELLAN under the grant number ICT-FP7-611526.Display devices on and around the body such as smartwatches, head-mounted displays or tablets enable users to interact on the go. However, diverging input and output fidelities of these devices can lead to interaction seams that can inhibit efficient mobile interaction, when users employ multiple devices at once. We present MultiFi, an interactive system that combines the strengths of multiple displays and overcomes the seams of mobile interaction with widgets distributed over multiple devices. A comparative user study indicates that combined head-mounted display and smartwatch interfaces can outperform interaction with single wearable devices.Postprin
