Absent-mindedness is a diagnosable mental health condition which individuals experience lapses of attention. Absent-mindedness has many causes and could be experienced by a wide range of populations. Experiencing absent-mindedness is inconvenient and disturbing, and it could lead to forgetful behaviors, such as forgetting important items like wallets and keys. Experiment 1 of the present study examined whether a new type of “smart tray” for storing small personal items could mitigate the effect of absent-mindedness through the implementation of visual feedback and development of user’s motor memory. In experiment 2, we added haptic feedback and acoustic feedback to the smart tray we used in experiment 1 to establish a feedback ecosystem. The motor memory training outcome and treatment effect to absent-mindedness of the three types of trays (visual feedback vs. no feedback vs. multiple feedbacks) were evaluated and compared to each other. Results show that the visual feedback group achieved better motor memory performance, was less affected by absent-mindedness, and had better user experience than the no feedback group. The feedback ecosystem group achieved the best motor memory performance and was even less affected by absent-mindedness than the visual feedback group. However, they had the worst user experience among the three groups. The findings suggest that implementing visual feedback and multiple feedbacks to train people’s motor memory is effective to mitigate or prevent absent-mindedness, but it is important to evaluate both the positive and negative impacts of each feedback method and to find the correct combination of feedback methods to optimize the product’s effectiveness.
