User Experience (UX) is a key factor and an opportunity for improvement in digital products. Traditionally, it has been evaluated retrospectively through surveys and interviews. However, retrospective and subjective evaluation is not in all cases the optimal approach, as it does not evaluate the UX at the time of human-machine interaction, and therefore may not project reality due to inaccurate recall.

ABSTRACT: User Experience (UX) is a key factor and an opportunity for improvement in digital interfaces. Traditionally, it has been evaluated retrospectively through surveys and interviews. However, this is not always the optimal approach, as it does not measure UX at the moment of human-machine interaction and is therefore prone to human error due to inaccurate recall. Thus, physiological monitoring is emerging as a promising technique to assess UX during interactions. This paper aims to identify UX case studies carried out with physiological monitoring by means of a Systematic Literature Review (SLR). The results of the 33 UX case studies reviewed show that interest in incorporating physiological technologies in UX studies is growing and expanding into different fields. The electroencephalogram (EEG) was found to be the most used physiological tool, and the most used set of tools was the Galvanic Skin Response (GSR) with the electrocardiogram (ECG). In addition, the average number of participants was obtained depending on the physiological tool used. The research opportunities identified are: 1) the combination of different methods and tools in the assessment of UX, and 2), the validation of a sample size for UX tests performed with physiological monitoring Keywords: User Experience (UX), evaluation, Systematic Literature Review (SLR), physiological monitorization

Successful interaction with complex systems is based on the system ability to satisfy the user needs during interaction tasks, mainly related to performances, physical comfort, usability, accessibility, visibility, and mental workload. However, the “real” user experience (UX) is hidden and usually difficult to detect. The paper proposes a Transdisciplinary Assessment Matrix (TAS) based on collection of physiological, postural and visibility data during interaction analysis, and calculation of a consolidated User eXperience Index (UXI). Physiological data are based on heart rate parameters and eye pupil dilation parameters; postural data consists of analysis of main anthropometrical parameters; and interaction data from the system CAN-bus. Such a method can be adopted to assess interaction on field, during real task execution, or within simulated environments. It has been applied to a simulated case study focusing on agricultural machinery control systems, involving users with a different level of expertise. Results showed that TAS is able to validly objectify UX and can be used for industrial cases.

Face expression recognition (FER) has gained very much attraction to researchers in the field of computer vision because of its major usefulness in security, robotics, and HMI (Human-Machine Interaction) systems. We propose a CNN (Convolutional Neural Network) architecture to address FER. To show the effectiveness of the proposed model, we evaluate the performance of the model on JAFFE dataset. We derive a concise CNN architecture to address the issue of expression classification. Objective of various experiments is to achieve convincing performance by reducing computational overhead. The proposed CNN model is very compact as compared to other state-of-the-art models. We could achieve highest accuracy of 97.10% and average accuracy of 90.43% for top 10 best runs without any pre-processing methods applied, which justifies the effectiveness of our model. Furthermore, we have also included visualization of CNN layers to observe the learning of CNN.

Machine Interaction

Electric power wheelchairs (EPWs) enhance the mobility capability of the elderly and the disabled, while the human-machine interaction (HMI) determines how well the human intention will be precisely delivered and how human-machine system cooperation will be efficiently conducted. A bibliometric quantitative analysis of 1154 publications related to this research field, published between 1998 and 2020, was conducted. We identified the development status, contributors, hot topics, and potential future research directions of this field. We believe that the combination of intelligence and humanization of an EPW HMI system based on human-machine collaboration is an emerging trend in EPW HMI methodology research. Particular attention should be paid to evaluating the applicability and benefits of the EPW HMI methodology for the users, as well as how much it contributes to society. This study offers researchers a comprehensive understanding of EPW HMI studies in the past 22 years and latest trends from the evolutionary footprints and forward-thinking insights regarding future research.
