“…Our simulator, based on well-known literature findings [ 25 , 27 ], like the Hick-Hyman law for cognitive information capacity [ 28 , 29 ] and Fitts' law for human movement [ 30 ] became capable of predicting the number of interaction events within infotainment scenarios and the time needed to complete them [ 31 ]. Hick's law states that the time between a stimulus and the user's response is increasing by the number of available choices at any given time.…”

Virtual user modeling research has attempted to address critical issues of human-computer interaction (HCI) such as usability and utility through a large number of analytic, usability-oriented approaches as cognitive models in order to provide users with experiences fitting to their specific needs. However, there is demand for more specific modules embodied in cognitive architecture that will detect abnormal cognitive decline across new synthetic task environments. Also, accessibility evaluation of graphical user interfaces (GUIs) requires considerable effort for enhancing ICT products accessibility for older adults. The main aim of this study is to develop and test virtual user models (VUM) simulating mild cognitive impairment (MCI) through novel specific modules, embodied at cognitive models and defined by estimations of cognitive parameters. Well-established MCI detection tests assessed users' cognition, elaborated their ability to perform multitasks, and monitored the performance of infotainment related tasks to provide more accurate simulation results on existing conceptual frameworks and enhanced predictive validity in interfaces' design supported by increased tasks' complexity to capture a more detailed profile of users' capabilities and limitations. The final outcome is a more robust cognitive prediction model, accurately fitted to human data to be used for more reliable interfaces' evaluation through simulation on the basis of virtual models of MCI users.

“…As one of the most typical and widely used cognitive architecture and a unified theory of cognition [7], ACT-R aims at using software to simulate a full range of cognitive tasks, has been used to construct models to simulate human's task performing and cognitive process, such as Beckmann and Yilmaz(2012) introduce a realization of a more complicated interactive warning framework to avoid operator mistakes during maintenance [8], Kennedy and Patterson (2102) present an ACT-R model to predict the development of intuitive decision-making in humans [9] etc. In addition, ACT-R has been used to access and improve human's performance in complex and adaptive system such as aircraft operations, nuclear power operations and supervisory control.…”

Astronauts are exposed to numerous stressors during spaceflights, to reduce the faulty operations and improve human performance in manually controlled rendezvous and docking (manual RVD) of space vehicles, a method, which applies sophisticated cognitive architecture Adaptive control of thought-rational (ACT-R ) to model astronaut's cognitive behaviors and investigate the cognitive components influencing human performance, is proposed in this paper . To model the cognitive behaviors in completing manual RVD task, the declarative knowledge of the cognitive processes was obtained from experiments, the procedural knowledge was acquired by analyzing the relationship between cognitive processes and behaviors, and the model parameters were set up according to the boundary conditions and task characteristics. Manual RVD cognitive behavior model is then built up based on the declarative knowledge, the procedural knowledge and the model parameters. Comparisons of model running results and manual control results were performed to test the model's validation. ACT-R control panel tool was also used to analyze the process of model's running and manual control behaviors. Results of the comparisons indicate that the ACT-R model proposed in this paper is in accordance with human cognitive behaviors.
