Summary of the themes on usability, usefulness and needs, model understanding, and trust
My journal paper for Agriculture presents a prototypical visual decision support system that incorporates price prediction, uncertainty, and visual analytics techniques. Interviews and questionnaires suggest that user-centred approaches are key for increasing the uptake of visual decision support systems in agrifood.
