商品描述
This book presents extensive research on the quality of 360 video perceived by users with HMDs. The book aims to develop a set of standard guidelines for the systematic visual quality assessment of 360 videos. Firstly, conventional subjective test methods such as Absolute Category Rating (ACR) and Double Stimulus Impairment Scale (DSIS) are applied to evaluate video quality, alongside the Modified ACR (M-ACR) method newly proposed. Building on the reliability and general applicability of the procedure across different tests, a methodological framework for 360 video quality assessment is then presented. The author also analyzes simulator sickness to investigate the impact of different influencing factors. The insights gained on simulator sickness related to 360 video contribute to a better understanding of this particular use case of VR and can help to improve comfort among users by suggesting improvements in the technical specifications of 360 video and HMD technology and thusimproving QoE.
商品描述(中文翻譯)
本書對使用 HMD（頭戴式顯示器）所感知的 360 度視頻質量進行了廣泛的研究。書中旨在制定一套標準指導方針，以系統性地評估 360 度視頻的視覺質量。首先，應用傳統的主觀測試方法，如絕對類別評分（Absolute Category Rating, ACR）和雙刺激損傷量表（Double Stimulus Impairment Scale, DSIS）來評估視頻質量，並引入新提出的修訂 ACR（Modified ACR, M-ACR）方法。在不同測試中，基於程序的可靠性和普遍適用性，隨後提出了一個 360 度視頻質量評估的方法框架。作者還分析了模擬器暈動症，以研究不同影響因素的影響。對於與 360 度視頻相關的模擬器暈動症所獲得的見解，有助於更好地理解這一特定的虛擬實境（VR）使用案例，並通過建議改進 360 度視頻和 HMD 技術的技術規格來提高用戶的舒適度，從而改善用戶體驗（QoE）。
作者簡介
Ashutosh Singla received his M.Sc degree in Communications Engineering from RWTH Aachen in May 2015, with a master's thesis on HEVC video coding optimization (Prof. Jens Rainer Ohm). From March 2016 to September 2016, he worked in the Multimedia Signal Processing Group (MMSPG, Prof. Touradj Ebrahimi) at the Swiss Federal Institute of Technology (EPFL), Lausanne, Switzerland, on a project for food image classification and recognition. Since September 2016, he has been working in the Audiovisual Technology Group at TU Ilmenau. In February 2022, he got his PhD in the field of Video Quality and Simulator Sickness Assessment for 360° videos under the supervision of Prof. Dr.-Ing. Alexander Raake.
