In the last decade, we have been experiencing an increasing level of intelligence that the objects in the Internet of Things (IoT) have been augmented with, especially in the direction of giving them cognitive and socialization capabilities. We believe that this evolution should go further in the direction of the Emotional Intelligence, which allows humans to be successful in their lives. EmIoT is the resulting paradigm that we propose, which is aimed to increase the Quality of Experience delivered by IoT applications by making IoT capable of: understanding peoples needs by observing them; better management of its own resources on the basis of users emotional state; creating a level of affection to be used for leveraging the level of interaction between IoT and users. The paper's contribution lies in the definition of the paradigm, the analysis of the new functionalities the IoT should be augmented with, and the preliminary investigation of the possible EmIoT architecture.

In this paper we describe a set of video subjective tests with 498 student viewers in the age range 9–17. These tests are based on earlier tests that we carried out with adult viewers. The aim was not to validate our earlier results, but to use them as a reference against which we could compare the scores of the students, to allow us to address the questions of how sensitive students in this age range are to video quality issues, and how suitable they would be as viewers in subjective tests. We used the same test content as in our earlier tests, including content at high and ultra-high resolution, and with standard and high dynamic range.

Virtual Reality (VR) multiplayer games are currently developed more frequently, while in parallel VR is becoming more accessible to the broader public. Also exergames, which refer to computer games combined with a physical activity, are getting widely available, driven by developments in sensor technologies. In this paper, we present results of a multiplayer exergame experiment where two players race against each other four times on two rowing ergometers. Experimental conditions were type of environment (with VR vs. without VR) and the possibility of conversation with the opponent (conversation enabled vs. conversation disabled). To measure subjective experience, participants rated perceived flow, sense of presence and social presence on standardized questionnaires. Results show that the type of environment has a significant influence on the perceived presence, as participants rated the presence higher in VR. The possibility of conversation resulted in a perception of a significantly higher social presence. This illustrates that the usage of virtual environments as well as the possibility of conversations between users are highly valuable to increase the Quality of Experience during exergames. In our future research, we plan to further investigate means to improve the user experience by applying gamification, different representations of opponents, and to assess the impact of network impairments during multiplayer scenarios.

User surveys for Quality of Experience (QoE) are a critical source of information for application developers. In addition to the common “star rating” used to estimate Mean Opinion Score (MOS), more detailed survey questions (problem tokens) about specific areas provide valuable insight into the factors impacting QoE. This paper explores two aspects of problem token questionnaire design. First, we study the bias introduced by fixed question order, and second, we provide a methodology to manage the size of the survey while keeping it informative. Based on 900,000 calls gathered using a randomized controlled experiment from Skype, we find that token selections can be strongly biased due to token positions and display design. This selection bias can be significantly reduced by randomizing the display order of tokens. It is worth noting that users respond to the randomized-order variant at levels that are comparable to the fixed-order variant. The effective selection of a subset of tokens is achieved by extracting tokens that provide the highest information gain over user ratings. This selection is known to be in the class of NP-hard problems. We apply a well-known greedy submodular maximization method on our dataset to capture 94% of the information using just 30 % of thequestions.

Light field acquisition devices can capture static and dynamic information of the light field in space that is processed using computational imaging techniques for creating visual representation of the captured scene. The main applications are the creation of visual effects such as perspective change, refocusing, recoloring. Advances in light field technologies will provide the devices and tools needed for the development of new services in the virtual/augmented/merged reality domains. This paper presents an analysis of the effects of light field subsampling on the quality of experience in refocusing applications.

In this paper, we evaluate the influence of different VR rendering styles on the QoE of users of a training application. To this end, we present the results of a lab-based QoE study featuring a virtual manufacturing training setting in which participants were asked to correctly allocate spare parts to mounting locations inside and outside a vehicle using an HTC Vive VR Setup. We evaluate how five different rendering styles (defined by rendering technique and shader used), ranging from point cloud to highly photo-realistic, affect different quality dimensions such as perceived visual quality, task difficulty, spatial orientation ability, and discomfort (including cyber-sickness). Our results show that while rendering style has a significant impact on QoE and other dimensions (like task completion time), a standard shader already can provide sufficient quality to support the provided training task and can even outperform rendering styles using more sophisticated techniques like ambient occlusion. Furthermore, we also discuss significant influence of user-related factors like previous experience with VR or gender as well as other related critical issues to be considered in VR training application and assessment study design.

Subjective assessment for image or video qualities is considered as the most reliable way to obtain the ground truth for the development of objective quality metrics, especially when leaded by Mean Opinion Score (MOS approaches). However, obtained MOS with standard protocols are noisy due to subject's personal characteristics, such as viewing experience, gender or profession, leading to uncertain ground truth driven by the number of panelists/subjects. The usual way to reduce uncertainty relies on raising this number. In this paper, we demonstrate how a recently introduced Maximum Likelihood Estimation (MLE) based quality recovery model can improve the discriminability of standard subjective quality assessment. Compared to straightforward MOS computation, we present a case study where one can save between 26% to 39% in terms of numbers of subjects at the same discriminability.

Experience assessment is a key activity for understanding and developing interactive systems and technologies. Virtual reality (VR) is no exception, considering its rising popularity and the increasing availability of affordable VR devices. However, in experience studies where participants typical have to rate multiple test conditions presented to them, having to repeatedly take off the head mounted display (HMD) just for the purpose of issuing ratings is cumbersome and breaks the immersion. As a solution we present VRate, a Unity3D asset to integrate subjective experience questionnaires directly in virtual reality environments. The suitability of VRate has been proven by successfully using the asset in a QoE and a UX study. We describe the technical implementation and suggest how to integrate the VRate in a study setup. VRate will be provided to the scientific community for research purposes, educational and noncommercial usage under a Creative Commons License.

The quality of adaptive streaming may fluctuate strongly during a session. Therefore, a challenge is how to evaluate the quality of a session over time. In this study, a cumulative quality model is proposed for HTTP adaptive streaming. The model is based on the concept of a sliding window of video segments over a session. It is found that the minimum window quality, the last window quality, and the average window quality are key components of the cumulative quality model. In addition, the proposed model is applicable to real-time quality monitoring, which is especially important for cost-effective evaluation of streaming technologies and as basis for adaptive quality mechanisms.

Recent advances in haptic communication cast light onto the promise of full immersion into remote real or virtual environments. The quality of compressed haptic signals is crucial to fulfill this promise. Traditionally, the quality of haptic signals is evaluated through a series of subjective experiments. So far, only very limited attention was directed toward developing objective quality measures for haptic communication. As touch applications continue to grow, the need for efficient haptic quality assessment (HQA) measures is becoming more pronounced. In this work, we attempt to pragmatically approach this problem inspired by recent advances in the visual domain. More specifically, we design a HQA measure based on our knowledge of human haptic perception represented by Stevens power law and a similarity comparison between a reference and a compressed haptic force-feedback signal represented by the SSIM index as a full-reference quality measure. The proposed HSSIM measure provides clear advantages over existing approaches. We validate the performance of the proposed HQA measure with subjective experiments which show high correlation with human quality assessment results.
