Quickdraw: The impact of mobility and on-body placement on device access time | PDF
What if you could get to your information faster? We studied how fast people could get to devices placed in different on-body locations.

Abstract: We investigate the effect of placement and user mobility on the time required to access an on-body interface. In our study, a wrist-mounted system was significantly faster to ac- \\cess than a device stored in the pocket or mounted on the hip. In the latter two conditions, 78% of the time it took to access the device was spent retrieving the device from its holder. As mobile devices are beginning to include peripherals (for example, Bluetooth headsets and watches connected to a mobile phone stored in the pocket), these results may help guide interface designers with respect to distributing functions across the body between peripherals.
