“…Recent studies could show that applications such as tablet mobile devices with integrated memory training apps can be used even by people with early stage of dementia [ 1 , 2 ]. Some reviews reported that exergames that combine physical activity with digital gaming have also been found wide application in healthy [ 3 ], disabled older adults [ 4 ], and in people with cognitive impairment or dementia [ 5 - 7 ]. Just to name a few examples, a computerized Tai Chi game using the Microsoft’s motion-capture device Kinect [ 8 ] or a computer tele-rehabilitation platform that combines game-based exercises with telemonitoring [ 9 ] has the potential to improve motor and cognitive functions in the older population.…”

BackgroundExergames often used for training purpose can also be applied to create assessments based on quantitative data derived from the game. A number of studies relate to these use functionalities developing specific assessment tasks by using the game software and provided good data on psychometric properties. However, (1) assessments often include tasks other than the original game task used for training and therefore relate to similar but not to identical or integrated performances trained, (2) people with diagnosed dementia have insufficiently been addressed in validation studies, and (3) studies did commonly not present validation data such as sensitivity to change, although this is a paramount objective for validation to evaluate responsiveness in intervention studies.ObjectiveSpecific assessment parameters have been developed using quantitative data directly derived from the data stream during the game task of a training device (Physiomat). The aim of this study was to present data on construct validity, test–retest reliability, sensitivity to change, and feasibility of this internal assessment approach, which allows the quantification of Physiomat training effects on motor-cognitive functions in 105 multimorbid patients with mild-to-moderate dementia (mean age 82.7±5.9).MethodsPhysiomat assessment includes various tasks at different complexity levels demanding balance and cognitive abilities. For construct validity, motor-cognitive Physiomat assessment tasks were compared with established motor and cognitive tests using Spearman’s rank correlations (rs). For test–retest reliability, we used intra-class correlations (ICC3,1) and focused on all Physiomat tasks. Sensitivity to change of trained Physiomat tasks was tested using Wilcoxon statistic and standardized response means (SRMs). Completion rate and time were calculated for feasibility.ResultsAnalyses have mostly shown moderate-to-high correlations between established motor as well as cognitive tests and simple (rs=−.22 to .68, P ≤.001-.03), moderate (rs=−.33 to .71, P ≤.001-.004), and complex motor-cognitive Physiomat tasks (rs=−.22 to .83, P ≤.001-.30) indicating a good construct validity. Moderate-to-high correlations between test and retest assessments were found for simple, moderate, and complex motor-cognitive tasks (ICC=.47-.83, P ≤.001) indicating good test–retest reliability. Sensitivity to change was good to excellent for Physiomat assessment as it reproduced significant improvements (P ≤.001) with mostly moderate-to-large effect sizes (SRM=0.5-2.0) regarding all trained tasks. Completion time averaged 25.8 minutes. Completion rate was high for initial Physiomat measures. No adverse events occurred during assessment.ConclusionsOverall, Physiomat proved to have good psychometric qualities in people with mild-to-moderate dementia representing a reliable, valid, responsive, and feasible assessment strategy for multimorbid older adults with or without cognitive impairment, which relates to identical and integrated performances trained by using t...

“…The use of game technology and 3D game engine techniques for interactive visualisation is becoming increasingly popular in eHealth and health data analysis. Such works, for example, are an interactive environment for supporting the assessment, rehabilitation and prediction of dementia [36] and virtual reality for assessing cognition in the elderly [37].…”

In cancer biology, genomics represents a big data problem that needs accurate visual data processing and analytics. The human genome is very complex with thousands of genes that contain the information about the individual patients and the biological mechanisms of their disease. Therefore, when building a framework for personalised treatment, the complexity of the genome must be captured in meaningful and actionable ways. This paper presents a novel visual analytics framework that enables effective analysis of large and complex genomics data. By providing interactive visualisations from the overview of the entire patient cohort to the detail view of individual genes, our work potentially guides effective treatment decisions for childhood cancer patients. The framework consists of multiple components enabling the complete analytics supporting personalised medicines, including similarity space construction, automated analysis, visualisation, gene-to-gene comparison and user-centric interaction and exploration based on feature selection. In addition to the traditional way to visualise data, we utilise the Unity3D platform for developing a smooth and interactive visual presentation of the information. This aims to provide better rendering, image quality, ergonomics and user experience to non-specialists or young users who are familiar with 3D gaming environments and interfaces. We illustrate the effectiveness of our approach through case studies with datasets from childhood cancers, B-cell Acute Lymphoblastic Leukaemia (ALL) and Rhabdomyosarcoma (RMS) patients, on how to guide the effective treatment decision in the cohort.

“…Showing positive results in multiple domains, such as prevention [15], rehabilitation [14], neurocognitive stimulation [16], assessment [17] and monitoring neurocognitive changes [18], leading to beneficial changes, when it comes to brain plasticity [19], changing the brain's structure [20] and facilitating the impact of neurocognitive stimulation on everyday functioning [6]. However, the use of serious games, with older people, is still in an early phase [21] and there is little information when it comes to the impact of these programs on the users' quotidian activities and on their quality life [22].…”

The ageing process is naturally accompanied by changes in people's cognitive processes. The European population ageing is a challenge for the European social policy and for the mental health professionals. New technologies can play an important role in the neurocognitive stimulation area as they possess characteristics that might reduce the anxiety levels of patients participating in neurocognitive stimulation or assessment programs. In particular, serious games provide a setting that can be explored to improve the easy access to neurocognitive stimulation and assessment, regardless of place and time, at a lower cost then traditional approaches. This paper presents a serious game aiming to analyse neurocognitive deficits and stimulate the players' deficitary neurocognitive processes. This game is built on top of sound neurocognitive psychotherapy for adults, mainly addressing the cognitive processes of attention and memory. The game will simulate real world scenarios, allowing a better generalization process due to ecological validity.
