Consequently and we designed a multimodal mobile diet diary supporting interaction through text and graphics and speech. The diary and which gave personalized advice about maintaining a healthy diet based on meals entries and was evaluated with 32 older adults in a Smart Home Lab through use of scenarios. Results indicate that participantsâ€™ satisfaction was highest when the feedback was provided through text and graphics. We found no effect on the effectiveness and efficiency. Additionally and spatial ability and computer experience and age explained variance in the evaluation of the diary. Our findings show that a multimodal mobile diet diary can support older adults maintaining a healthy diet and give insights on designing usable mobile interfaces for older adults.</style></abstract></record></records></xml>
