Signages that elicit guilt is an effective strategy in influencing segregation behaviour especially if it includes a statement of action and an appropriate picture to illustrate the consequence of bad behavior. This paper examines the direct effect of signage design factors: type of guilt statement and pictorial component to guilt. Clarity of purpose was considered as a mediating variable between the design factors and guilt, while guilt proneness was considered as moderating variable between guilt and segregation behavior. The evaluation of the model was done through a Structural Equation Model (SEM) with a data set count of 404. There was no significant effect in the use of actual picture and cartoon in promoting the clarity of purpose of a signage. The mediating effect of clarity of purpose was established between the design factors and guilt, while guilt proneness also moderated the relationship between guilt and segregation behavior.

Self-evaluation and self-critics is a rare exercise, among the members or executive committees of academic and professional associations. Human factors and ergonomics associations throughout their seven decades of existence have rarely been evaluated. The aim of the present research is to highlight what objectives were achieved, what are the obstacles to attain the outlined objectives of the HF/E associations of the study sample, and what lessons can be learned throughout the existence of each society? To answer these questions, five responsible/representatives of four (4) HF/E associations participated in the discussion panel. Their answers to the three questions on: achievements, obstacles and lessons learned were stratified into categories of (1) achievements: seven goals have been achieved, (2) eight obstacles are facing HF/E societies to achieve their missions, and (3) twelve lessons are learned during life time of HF/E society from its inception to today. These results are discussed taking into account the context of each HF/E society, while having a critical eye when adopting experiences of other HF/E societies. Some of these are of great value, others cannot be applied locally. A particular emphasize steamed from the discussion among members of the panel is the implementation of workable strategies for short, medium and long terms to promote ergonomics at all levels.

Objective: To illustrate how fatigue affects the workload, situation awareness, and control strategy of air traffic controllers. Background: As air traffic control becomes more complex and demanding due to the increasing number of aircraft movements in major airport hubs, the need to particularly look into the interplay of performance shaping factors has also intensified. Despite the previous efforts of scholars to understand the framework of air traffic control based on factors on workload and situation awareness (SA) and its impact to shift in control strategy, the role of fatigue in such factors is ignored notwithstanding its relative impact on air traffic controllers as tasks are carried out in varying workload and work shift. Method: A case study is conducted in an actual tower control center in the Philippines to demonstrate the hypothesized relations among fatigue, workload, SA, and control strategy. Questionnaires based on SPAM, SASHA, Samn-Perelli fatigue scale, and visual attention self-report are deployed to measure air traffic controllers’ fatigue levels, SA, and control strategy. Results: Fatigue has an inverse relationship with workload and has a significant effect on SA. Furthermore, fatigue is also found to have a significant relationship with some areas of interest including visual display terminal. Conclusion: Such results underpin the resource allocation decisions of stakeholders in the commercial aviation industry geared toward fostering the welfare of air traffic controllers.

Objectives This study aims to characterize the working environment, stress levels, and psychological detachment of employees working from home during the COVID-19 pandemic in the Philippines and investigate their relationship to productivity and musculoskeletal symptoms. Methods Structural equation modeling was used to examine the direct effect of workstation characteristics, stress, and musculoskeletal symptoms to productivity and the indirect effect of psychological detachment to productivity. Data were gathered from a survey of employees working from home during the pandemic from different industries (n = 352). Multigroup analysis was also conducted to determine the effect of age, having a spouse, and having children less than 18 years old, to the model. Results Ergonomic suitability of the workstation (WES) has a significant effect on musculoskeletal symptoms (MSS) (β = −0.31, SE = 0.06; p < .001). Both workstation suitability (β = −0.24, SE = 0.03; p < .001) and workstation ergonomic suitability (β = −0.18, SE = 0.01; p < .01) inversely affect STR. Psychological detachment has a significant inverse effect on stress (β = −0.31, SE = 0.07; p < .001) and stress has a significant negative effect on productivity (β = −0.13, SE = 0.09; p = .03). Multigroup analyses showed that stress significantly affected the productivity of those without spouses and young employees. Conclusion Workstation suitability helps improve the productivity of people working from home while stress negatively affects it. Workstation ergonomic suitability and musculoskeletal symptoms have no significant effect.

Color is an important property of visualizations especially in the comprehension of complex line charts while chart size measured as distance between data points, is significant when dealing with numerous data points that are used for comparison. Multiple time-series line (MTSL) graphs are a common tool in visual representation of data but only a few studies explored the effect of visual properties on its comprehension. This study evaluated the effect of color properties (saturation and lightness), and vertical distance (chart height) in the comprehension of multiple time-series line graphs. It was posited that color palettes with higher saturation levels and charts with higher vertical distance improve comprehension. Comprehension was measured in terms of accuracy and response time using a discrimination task that required participants to find which time series possessed the highest value at a point. Six sets of multi-hued palettes with varying lightness and saturation were developed using colors equidistant in the color wheel. Two levels of chart heights were used to evaluate vertical distance. A total of ninety-two (92) subjects took part in the experiment. Results showed that when color saturation alone was considered, the highest saturation level was established to have the best user performance. Nevertheless, when the interaction of saturation with lightness was factored in the study, findings show that when colors with high level of lightness are used, they should have lower saturation levels and vice versa. This implies that there should be a balance between lightness and saturation when using colors in data visualizations. Vertical distance did not have a significant effect on comprehension, but a larger size generally resulted in better performance.

There was a shift in sustainability consumption in the last decade that stimulated new strategies for ecological friendly industries and new product innovations. Environmental labeling is a marketing technique used to inform consumers that a company has employed a process to protect the environment. However, uncertainty remains concerning how eco-labels influence consumers. Buying green products can elicit emotion in consumers. When consumers buy eco-products, they feel that they are helping save the environment. Products provide certain emotional benefits and therefore affect mood and behavior. This study aims to examine how consumers who differ in environmental attitudes respond to eco-labels. Aside from this, it wants to determine the intensity and type of emotions elicited by these kinds of products based on a certain set of pre-purchase emotions. These emotions are still unknown. Also, it proposes the Green Emotion Model (GEM) 2.0 that correlates environmental attitudes, visual attention towards these eco-labels, emotion and the desirability of purchasing a product. This framework proposes that the environmental attitudes and awareness of consumers are crucial for them to look for this eco-label on a product. These environmental labels should be able to capture the attention of consumers and thus will provoke positive emotions and lead to the purchase of an eco-product.

In this study, a design framework that integrates functional and aesthetic attributes with apparent usability and affective quality was validated using prototypes. The framework was validated using a mobile phone which is a high involvement product. Product attributes that affected visual evaluation prior to usage were selected and categorized into functional and aesthetic attributes. Nine design alternatives were generated out of varied functional and aesthetic design attributes. A survey was used to evaluated each design alternative in terms of the pre-purchase dimensions of affective quality, apparent usability, and desirability. Structural equation modeling (SEM) was used to validate the design framework. After conducting the experiment, the model obtained has a good fit and the relationships were significant. It was found that affective quality has the greatest direct effect on desirability and apparent usability has the greatest total effect on desirability. Functional attributes have significant total effects on apparent usability and desirability. For comparative analysis, older people’s perception on functional attributes have a greater effect on apparent usability, affective quality and desirability. Finally, it can be said that apparent usability evokes more emotions for people having greater usability needs such as older people.

Engineers are expected to design systems and products for human use. However, the curriculums of most engineering courses do not include a course on human factors. Thus, engineers design products and systems considering only the technical aspects. This results in usability problems and poor performance in the market. This paper discusses some of the problems in designing buildings and workplace environments such as lack of thermal comfort, excessive illumination, poor layout, confusing design of controls, etc. A framework for integrating human factors in designing built environments will be proposed that will include a system for various engineering disciplines to communicate and consider the needs of the users at different stages of the design process.

This paper highlights a preference evaluation methodology for text entry methods in a touch keyboard smartphone using analytic network process (ANP). Evaluation of text entry methods in literature mainly considers speed and accuracy. This study presents an alternative means for selecting text entry method that considers user preference. A case study was carried out with a group of experts who were asked to develop a selection decision model of five text entry methods. The decision problem is flexible enough to reflect interdependencies of decision elements that are necessary in describing real-life conditions. Results showed that QWERTY method is more preferred than other text entry methods while arrangement of keys is the most preferred criterion in characterizing a sound method. Sensitivity analysis using simulation of normally distributed random numbers under fairly large perturbation reported the foregoing results reliable enough to reflect robust judgment. The main contribution of this paper is the introduction of a multi-criteria decision approach in the preference evaluation of text entry methods.
