An Android application that measures cognitive performance based on scientifically validated cognitive games for attention, short-term and long-term memory, speed, reaction time. The data are stored in order to be accessible from the reseachers, while the user can explore her scores through visualisations and history overview.
The Android application prototype represents a standalone Android application which handles cognitive performance data when completing the tasks and provides scheduling and alarm capabilities. All data collected is stored for later usage, for example visualizations and data mining.
The tasks are modules and were implemented as separate activities.
This section aims to provide insight on the functionality and extensibility of the task module developed for the project. The Data manipulation module serves basically as a translator between the format in which the data is being saved and the Android object oriented programming language. For developing purposes, the data is stored at the moment in the external file system of the mobile phone. Specifically the data file is handled externally as JSON data. In this regard the google free library GSON has been employed. The general idea is that the data operations types are parsing from Object to JSON and reverse, writing to file and reading from file. Most of the data operations are self explanatory
