The article presents a research study on recognizing therapy progress among children with autism spectrum disorder. The progress is recognized on the basis of behavioural data gathered via five specially designed tablet games. Over 180 distinct parameters are calculated on the basis of raw data delivered via the game flow and tablet sensors - i.e. touch screen, accelerometer and gyroscope. The results obtained confirm the possibility of recognizing progress in particular areas of development. The recognition accuracy exceeds 80%. Moreover, the study identifies a subset of parameters which appear to be better predictors of therapy progress than others. The proposed method - consisting of data recording, parameter calculation formulas and prediction models - might be implemented in a tool to support both therapists and parents of autistic children. Such a tool might be used to monitor the course of the therapy, modify it and report its results.

The paper concerns the automation of measuring progress of children with autism spectrum disorder. The proposed approach combines diverse approaches: e-technologies and mobile applications for autism, behavioral metrics derived from gyroscope and game state with machine learning methods to find interconnections between the metrics and the progress of a child. The paper presents a gyroscope-based game, specifically designed as an investigation tool for therapy progress monitoring. The game enables registration of behavioral patterns of use of the applications and tablet. The paper presents how the game was used in a study of behavioral metrics. 31 children with autism took part in the study. Each of them played the game several times during a 6-months period. The data gathered during the gameplay are used to calculate a set of metrics, that might be used in evaluation of a child's progress. Results in terms of classification accuracy reach 80%, however they depend on the particular skill category. The best accuracies are obtained for evaluation of stereotypic behaviors and gross motor skills of a child. The approach presented in the study is novel and was not applied before, therefore it might be interesting for other researchers working on supporting technologies for autism. The results might be also interesting for practitioners applying e-technologies in autistics therapy.

Te paper reports current stage of the project Automated Terapy Monitoring for Children with Developmental Disorders of Autism Spectrum (AUTMON), that aims at development of methods and tools to allow for the automatic evaluation of the therapy progress among children with autism. Finding objective measures suitable for evaluating therapy progress would let create a system supporting those who diagnose autism and the therapists working with the children. In future these measures could be also applied as optimization criteria in defning the optimal therapy path. Such tool could be helpful in preparing the therapy plan, choosing the type of tasks and their frequency. It might also follow the therapy course, predict its direction and indicate the points which probably require intervention and changing the plan. Obviously it would never replace a therapist, but make his work more effective. Moreover, it could also support the parents in their efforts to objectively report valuable observations to the therapists, which would be especially important in the case of a limited access to therapy centers.

The article describes the idea of detecting stress among programmers on the basis of keystroke dynamics. An experiment with a group of students of artificial intelligence classes was performed. Two samples of keystroke data were recorded for each case, the first while programming without stress, the second under time pressure. A number of timing and frequency parameters were calculated for each sample. Then statistical analysis was performed to evaluate the significance of keystroke parameters changes. It turned out that some of the defined features might be indicators of being stressed.

Raport powstał w ramach projektu Automatyzacja pomiarów postępów terapii dzieci z zaburzeniami rozwoju ze spektrum autyzmu (AUTMON), finansowanego z programu Innowacje Społeczne, NCBR, (nr projektu: IS-2/6/NCBR/2015). Projekt jest realizowany w konsorcjum Politechnika Gdańska, Harimata sp z o.o., Fundacja Hipoterapia i ma na celu opracowanie metody automatycznego pomiaru wybranych aspektów funkcjonowania dzieci z autyzmem na podstawie interakcji ze specjalnie przygotowanymi aplikacjami mobilnymi. Raport zawiera sprawozdanie z wykonanych pomiarów w ramach zadania 2 projektu.
