Interface designs for pen-based mobile video browsing

Interfaces for timeline-based mobile video browsing

“…Given the high relevance of parameter optimization and usability evaluation, naturally, further user studies are one of our main interests for future work -for example, comparative evaluations with our previous work [3,4] and tests in true mobile scenarios, where people use the interface designs in an actual mobile situation, (e.g., while riding the bus or when walking), as already mentioned in Section 2 and 4, respectively. In the experiments presented here, participants had to solve different problems that represent typical browsing task, i.e.…”

“…[3]). Our own work in this context includes the MobileZoomSlider [3] and the ScrollWheel design [4]. Both approaches combine speed-with position-based navigation by providing several sliders at different granularity levels and a wheel-shaped interface, respectively.…”

Scrubbing Wheel: An Interaction Concept to Improve Video Content Navigation on Devices with Touchscreens

“…The same interaction concept has been proposed for video content navigation on PDAs and smartphones in a follow-up work [3]. The authors further suggested circular navigation gestures for stylusbased navigation in video and presented a few different interaction concepts in [1]. However, unfortunately in the evaluation no direct comparison to seeker-bar navigation was performed.…”

“…Our video navigation interface is based on the findings of [1] for stylus-based video navigation. Its interaction concept is inspired by the original Click Wheel hardware design of the classic Apple iPod device.…”

“…This navigation interface, called Scrubbing Wheel, provides superior navigation performance and higher user experience than the commonly used seekerbar. The idea of the interface is based on the findings of [1] and inspired by the hardware design of classic Apple iPod devices, which used a ClickWheel for media interaction where the user could start/pause music by clicking and browse files by performing a circular wipe gesture. We use the same interaction concept for navigation in video files through touch interaction and evaluate it with modern smartphones.…”
