Advancing NASA-TLX: Automatic User Interaction Analysis for Workload Evaluation in XR Scenarios
Full text linkPresented at: 2024 IEEE Gaming, Entertainment, and Media Conference, GEM 2024, Turin, 5 June 2024 through 7 June 2024This version of the paper has been accepted for publication.[Abstract]: Calculating the effort required to complete a task has always been somewhat difficult, as it depends on each person and becomes very subjective. For this reason, different methodologies were developed to try to standardize these procedures. This article addresses some of the problems that arise when applying NASA-Task Load Index (NASA-TLX), a methodology to calculate the mental workload of tasks performed in industrial environments. In addition, an improvement of this methodology is proposed to adapt it to the new times and to emerging Extended Reality (XR) technologies. Finally, a system is proposed for automatic collection of user performance metrics, providing an autonomous method that collects this information and does not depend on the users' willingness to fill in a feedback questionnaire.This work has been funded by grant PID2020-118857RA-100 (ORBALLO) funded by MCIN/AEI/10.13039/501100011033 and by Centro Mixto de Investigación UDC-NAVANTIA (IN853C 2022/01), funded by GAIN (Xunta de Galicia) and ERDF Galicia 2021-2027.Xunta de Galicia; IN853C 2022/0

Image, anxiety and attitudes towards death before COVID-19 and three years later: A study with adolescents
Full text link[Resumen] Los trastornos de ansiedad y la depresión han aumentado como consecuencia de la COVID-19. El objetivo de este estudio es examinar la influencia de la pandemia y el género en las imágenes de la muerte, la ansiedad ante la muerte y las actitudes hacia la muerte en un grupo de adolescentes de secundaria. Un mes antes del comienzo de la pandemia, se entregaron pruebas que medían las imágenes de la muerte, la ansiedad ante la muerte y las actitudes hacia la muerte a 195 participantes, y 134 participantes realizaron las mismas pruebas tres años después, justo tras el final de la pandemia. La comparación de las puntuaciones antes y después de la pandemia no muestra diferencias significativas en las imágenes de la muerte o la ansiedad ante la muerte entre ambas. Después de la pandemia, los participantes mostraron una mayor Aceptación de Aproximación (AA) y Aceptación Neutral (NA), mientras que las mujeres experimentaron más Miedo a la Muerte (FD) y una mayor Aceptación de Escape (EA) que los hombres. Los resultados se explican teniendo en cuenta los momentos en que se realizaron las pruebas, así como las características de los participantes.[Abstract] Anxiety disorders and depression have increased as
a result of COVID-19. The aim of this study is to examine the
influence of the pandemic and gender on death imagery, death
anxiety and attitudes towards death among a group of 319 high school adolescents. A month before the beginning of the
pandemic, tests measuring death imagery, death anxiety and
attitudes towards death were handed out to 195 participants, and 134 participants took the same tests three years later, right after the end of the pandemic. The comparison of pre- and post-pandemic scores shows no significant differences
in death imagery or death anxiety between the two. After the
pandemic, participants showed higher Approach Acceptance
(AA) and Neutral Acceptance (NA), while women were found
to experience more Fear of Death (FD) and higher Escape
Acceptance (EA) than men. Results are explained considering
the times at which the tests were taken as well as the participants’ characteristic
