When using direct-touch displays, the users' fingers sometimes occlude the content. To avoid this problem, previous studies have proposed using the back side of a device [Hiraoka et. al., 2003] [Wigdor et al., 2007]. These approaches were shown to be useful for inputting from the backside of a device, for tasks such as selecting targets. Although these approaches have not been shown the usability of double sided touch displays, we explored how users touch both sides of a transparent display using the LimpiDual Touch (LDT) [Iwabuchi et al., 2008]. In our experiments, participants touched a target on the double-sided display. The location of the target was not predictable. We compared the reaction time (RT) and accuracy under the different input conditions (front/back/dual).
