We present our novel naturalistic laboratory setup that facilitates the presentation of real-world live-action stimuli by physically present actors in a controlled manner. Participants observe live-action stimuli through a screen, which is surrounded by ...

Social robots have revolutionized social interaction and communication. This study explores our perception of robots, focusing on the factors influencing evaluations of Agency and Experience - two dimensions of mind perception. Three distinct aspects of ...

Popularity bias in recommendation lists refers to over-representation of popular content and is a challenge for many recommendation algorithms. Previous research has suggested several offline metrics to quantify popularity bias, which commonly relate the ...

Most user studies in the QoE multimedia domain are done by asking users about quality. This approach has advantages: it obtains many answers and reduces variance by repeated measurements. However, the results obtained in this context may be different ...

Deeply immersive experiences are intrinsically rewarding; evoking them for another is a cornerstone of success in artistic or design practice. At the same time, modern interfaces have created a state of ’partial continuous attention’, and frequent self-...

In fields where in situ performance cannot be measured, ecological validity is difficult to estimate. Drawing on theory from social psychology and virtual reality, we argue that face validity can be a useful proxy for ecological validity. We provide ...

Current stress induction methods are often too theoretical and do not reflect to real life scenarios. In this study, we used a dual task paradigm in virtual reality, combining a navigation task with a reaction task. With this setup, we aimed at creating ...

There is a growing body of research focusing on the ecological validity of neuropsychological assessments. For some authors, the neurocognitive tests should be developed to assess the operation of cognitive functions in real-world activities. This ...

The ecological validity of password studies is a complex topic and difficult to quantify. Most researchers who conduct password user studies try to address the issue in their study design. However, the methods researchers use to try to improve ...

In this paper, we present MoCCha, a mobile campus application used not only as a subject of research, but as a research platform for a number of scientific disciplines. Using apps that are available from mobile application stores enables studying user ...

We describe the use of a technique aimed at allowing users to realistically experience novel mobile applications in a naturalistic environment as part of the formative evaluation of the system. This technique, that we have named naturalistic enactment, ...

Catching a flying ball is a difficult task that requires sensory systems to calculate the precise trajectory of the ball to predict its movement, and the motor systems to drive the hand in the right place at the right time.

In this paper we have ...

We present the results of an in-situ evaluation of a mobile application aimed at assisting geriatric nurses in attending emergency calls from elders. Nurses use the application for assistance in providing a recommendation to elders. One of the main ...

An important question for ecologically valid virtual environments is whether cohort characteristics affect immersion. If a method for assessing a certain neurocognitive capacity (e.g. attentional processing) is adapted to a cohort other than the one that ...

The traditional approach to assessing neurocognitive performance makes use of paper and pencil neuropsychological assessments. This received approach has been criticized as limited in the area of ecological validity. While virtual reality environments ...

Motivation - Combination of qualitative and quantitative methodologies to develop a simulated environment to study decision-making processes from a NDM perspective. Research approach - Discourse analysis to find interpretative repertoires, use of Visual ...

Subjective quality evaluation is used to optimize the produced audiovisual quality from fundamental signal processing algorithms to consumer services. These studies typically follow the basic principles of controlled psychoperceptual experiments. ...

This paper describes the current state of our ongoing work developing tools for tracking player enjoyment in traditional face-to-face tabletop gaming situations. The challenge presented is that of quantifying game enjoyment whilst minimising the effects ...

The results presented in this paper illustrate how a specific map visualization technique is sensitive to setting: a comparative evaluation of the technique gives conflicting results depending on where it takes place. While prior research has explored ...

Non-traditional environments often change rapidly without forewarning, are difficult or impossible to control, and have other environmental and operational constraints that cannot easily be modeled in a laboratory, partly because the necessary level of ...
