Mobile stereoscopic 3D (S3D) user experience (UX) design has not yet been widely studied. Stereoscopy in today's products is used for visual design purposes, whilst the potential for holistic interaction design and utilitarian aspects have been neglected. In this paper we introduce the design, implementation and evaluation of a mobile S3D phonebook application. In the application stereoscopy was used to augment the 2D user interface (UI) design to provide information related to the time when the last call with each phonebook contact was made. We describe the results of the pilot study charting the design directions, laboratory study of first impressions, and results of a field trial, where 21 participants used the application for a few days. The S3D UI design provoked first impressions related to entertainment and 2D UI to practical qualities, whereas the field study showed that our S3D phonebook design successfully demonstrated that utilitarian value can be incorporated to the design.

“…The question of how the stereoscopic depth effect could be used in UI design has been investigated in several studies. Using S3D is perceived as a potential way to group similar content items or to highlight contextual information in a user interface [53]. There have also been design proposals where object depth within S3D UIs has been considered as an informative parameter e.g.…”

Abstract. The penetration of stereoscopic 3D (S3D) output devices is becoming widespread. S3D screens range in size from large cinema screens, to tabletop displays, TVs in living rooms, and even mobile devices are nowadays equipped with autostereoscopic 3D screens. As a consequence, the requirement for interacting with 3D content is also increasing, with "touch" being one of the dominant input methods. However, the design requirements and best practices for interaction with S3D touch screen user interfaces are only now evolving. To understand the challenges and limitations S3D technology brings to interaction design, and in particular the additional demands they place on the users of such interfaces, we present our research that considers stereoscopic touch screens of different sizes in static and mobile usage contexts. We report on perceptual, cognitive and behavioral aspects revealed by user studies and present interaction design requirements based on the findings.

“…for grouping items or highlighting contextual information, has been suggested (Ventä-Olkkonen et al, 2013). However, this work has generally not considered the usability of such designs beyond the static laboratory environment (Please note, later referrals to S3D in this paper, if not specified in detail, refer to mobile S3D).…”

ABSTRACT3D output is no longer limited to large screens in cinemas or living rooms. Nowadays more and more mobile devices are equipped with autostereoscopic 3D (S3D) touchscreens. As a consequence interaction with 3D content now also happens whilst users are on the move. In this paper we carried out a user study with 27 participants to assess how mobile interaction, i.e. whilst walking, with mobile S3D devices, differs from interaction with 2D mobile touchscreens. We investigate the difference in touch accuracy between 2D touchscreens and mobile S3D touchscreens and evaluate the minimum touch target size for mobile S3D touchscreens. The contributions of this paper are twofold: Firstly, we found the increase in minimum touch target size caused by walking was larger for a mobile S3D UI than for a 2D UI. Secondly, we present touch target sizes and aspect ratios required for reliable user interaction in each case. Additionally we examined differences in the angle at which users held the mobile S3D device compared to a 2D mobile device. We found that mobile S3D caused users to hold the device at a different angle when walking, compared to the 2D case. This first study of its kind provides valuable information to developers of the next generation of UIs and applications for mobile S3D displays and devices.
