Implementation and evaluation of a reminder registration interface for daily life objects

Abstract

There are many tasks regarding objects that are conducted according to specific date and time in daily life. To avoid forgetting to handle a task, reminder applications are useful. However, these tools require some effort on the part of the user to verbalize her or his task, e.g., “Read the book taken out from the library,” and input it to the system. To address this issue, we devised a model in which the user physically registers “the existence information of the task” to the object. This enables the user to notice the existence of a task related to the object and recall the content of the task every time he or she sees it. To realize this model, we propose a method for registering an object reminder by attaching clips to it. This makes it possible for the user to set the reminder only by attaching clips that have the specified duration information. Each clip has a full-color LED and displays the existence of task and deadline information associated to it. The evaluation result demonstrates that the proposed method yields better operability and acceptability for registering reminders than those of the conventional method.
