Abstract: An alarm unit includes an apparatus and a method of maximizing the efficiency of an alarm function that wakes up a sleeping user. An image input unit capable of photographing an eye image as a criterion for determining if the user has woken up is mounted on an alarm control apparatus. The image input unit mounted alarm control apparatus photographs a face image of the user, detects the eye region from the face image, and then determines a state of whether the user has woken up or not based on movement of the pupils in the eye region. If it is determined that the user keeps a waking state for a certain time, an alarm function is cancelled. By doing this, the alarm unit can help prevent the user from easily cancelling an alarm and maximize the efficiency of an alarm function that wakes up a sleeping user.

Abstract: Many devices are configured to present notifications to a user in an environment, such as mobile phones that ring or buzz to notify the user of an incoming call, and navigation devices that present verbal instructions to a driver of a vehicle. Many such devices present such audio notifications when information with potential relevance to the user is initially identified, but such techniques may interrupt an activity of the user, such as a conversation. Instead, a device may monitor an activity of the user within an environment to detect a notification opportunity when notifications may be presented to the user without interrupting the activity (e.g., a break in the conversation, or a gap of idle time between a first scheduled appointment and a second scheduled appointment). The device may present notifications of pertinent information to the user during the notification opportunities rather than interrupting the activity of the user.
