most of the evaluators agreed that the feedback provided by the system needs to be enhanced by adding audio messages and visual prompts in certain specific
occasions, e.g., for changes of the currently active mode, during the game play to indicate the number of remaining questions, as well as in correct and erroneous answers during the cards game. In relation to the last concern, the feedback providing method was suggested to be reconsidered so as to provide messages more promptly, and be enhanced with hints in case the learner has serious difficulties in answering
the question.
