We illustrate in this paper some of the negative emotions experienced by students when interacting with digital systems in learning situations, where there is a lack of feedback, or the interaction with digital systems is faulty. The emotions are classified here as feelings of: neglection, frustration, uncertainty, need for confirmation, and discomfort. We proposed thereafter two solutions. The first solution focuses on the design of digital feedback from a system which should arouse positive emotions. We discuss this in relation to universal design principle 5, tolerance for error. The second solution we propose is to provide feedback mechanisms for user feedback (user input). This may be considered when the first solution is not possible.
