Towards the design of an intuitive multi-view video navigation interface based on spatial information

Abstract

A Multi-View Video (MVV) is a set of related videos that capture an interesting scene from different perspectives at overlapping times. The work at hand is concerned with the design of innovative user interfaces (UI) for viewing MVVs. As a first contribution four different MVV UIs are designed. While different in design, their common aim is to allow a pleasant viewing and perspective switching experience by reducing the cognitive effort associated with constructing a mental map of the scene. This is achieved by incorporating the spatial relationships of the available views in the UI elements. As a second contribution a quality model is developed and a methodical evaluation process is designed. This is used to evaluate and compare the UIs. In a third contribution we use principal component analysis (PCA) to reveal information about the perceptual quality space which helps validating our proposed quality model. Based on the findings, a series of conclusions for best design practices are provided.

Multidimensional QoE of Multiview Video and Selectable Audio IP Transmission

“…Apostu et al have investigated the design of an intuitive user interface for MVV that makes effective use of available information about the spatial relationship of the individual perspectives [5]. This paper compares four user interfaces in terms of multidimensional QoE.…”
