Interactive video browsing on mobile devices

Abstract

Today, videos can be replayed on modern handheld devices, such as multimedia cellphones and personal digital assistants (PDAs), due to significant improvements in their processing power. However, screen size remains a limiting resource making it hard, if not impossible to adapt common approaches for video browsing to such mobile devices. In this paper we propose a new interface for the pen-based navigation of videos on PDAs and multimedia cellphones. Our solution -called the MobileZoomSlider -enables users to intuitively skim a video along the timeline on different granularity levels. In addition, it allows for continuous manipulation of replay speed for browsing purposes. Both interaction concepts are seamlessly integrated into the overall interface, thus taking optimum advantage of the limited screen space. Our claims are verified with a first evaluation which proves the suitability of the overall concept.

The Video Browser Showdown: a live evaluation of interactive video search tools

“…Many browsing tools, with better interaction means than provided by a typical video player, have been presented in the literature (for a detailed review see [29]). While many of them are advanced navigation methods (e.g., [7,8]), extended video players (e.g., [10,14,18]) or enhanced video content visualizations [6], some are highly sophisticated browsing tools (e.g., [1,25,30]). These sophisticated tools provide very specific interfaces and advanced interaction methods, such as combined mouse/keyboard interaction for 3D navigation, table-of-content navigation in videos, navigation trees and spatial interaction (e.g., [12,13,22,23,26,28]).…”

A new interface for video browsing on PDAs

“…The feasibility of our concept for video browsing on traditional desktop PCs has been evaluated in [3] and [4]. An evaluation of the PDA version described here can be found in [5]. An initial user study with 20 participants confirmed our statement that operation of the interface is easy and intuitive despite its complexity and the variety of offered interaction styles.…”

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

“…Hürst et al proposed the Mobile ZoomSlider interface [2] for stylus-based navigation on handheld devices. The basic idea is a virtual seeker-bar that can be used at any screen position.…”

“…In a recent work that builds on the idea of [6] and [2], we also proposed to use wipe gestures for navigation in videos on mobile devices instead of navigation with seeker-bars [8]. The idea in this work was to use simple wipe gestures for navigation in videos, as also used on touch-based devices for inspection of photo collections, documents, or slides of a presentation.…”
