Interaction with an autostereoscopic touch screen: effect of occlusion on subjective experiences when pointing to targets in planes of different depths
JOURNAL OF THE SOCIETY FOR INFORMATION DISPLAY(2012)
摘要
It is well known that the usability of a typical touch screen depends on several parameters, including interface design, device characteristics, and input operations. However, there is virtually no knowledge regarding how people evaluate interaction with 3D display-integrated touch screen. Twenty-one participants were asked to use standard touch screen to point to targets in planes of different planes on an autostereoscopic display and evaluate how natural and easy this action was. Clear differences in pointing experiences across depth levels and input operators were found. Pointing to targets in a back plane was reported to be more natural and easier than the same action with targets in a front plane. The use of finger input was less unnatural than the use of a stylus, but the use of stylus with icons in the front plane was more fun and entertaining.
