Abstract: A method is provided for controlling interaction among an information terminal, an electronic mail server, and a wearable terminal. The method causes an information terminal to receive electronic mail from an electronic mail server by using a mail application for executing transmission and reception of the electronic mail, the mail application being stored in a memory of the information terminal. The method also causes the information terminal to transfer the received electronic mail to a wearable terminal having a second display, and to receive viewing information from the wearable terminal, the viewing information indicating that the electronic mail was displayed on the second display. The method further causes the information terminal to determine whether the electronic mail is being displayed on the second display, and to automatically display, on the first display, a reply-mail creation screen for creating a reply mail to the electronic mail.

Abstract: A wearable terminal includes: a body having a display that performs display, a sensor that detects a first angle of rotation by which the display has been rotated with respect to a first axis as an axis of rotation, and a controller that controls the display according to the first angle of rotation; and a band that is connected to the body and extends around the forearm in an arcuate shape, wherein the first axis is perpendicular to a second axis and is parallel to a direction in which the forearm extends, when the first angle of rotation is within a first angle range, the controller causes a first display image displayed, and when the first angle of rotation changes from the first angle range to a second angle range, the controller causes a part of the first display image and a part of a second display image simultaneously displayed.

Abstract: In a wearable terminal, a controller determines whether a direction of a display surface detected by a detector is within a first angle range. In a case where a latest direction of the display surface is out of the first angle range, the controller puts the display in a sleep state, but otherwise the controller puts the display in an active state. Furthermore, the controller specifies a second angle range from the second reference direction. The controller switches the display from the sleep state to the active state in a case the controller determines that the plurality of directions of the display surface detected in the first period and that the direction of the display surface newly detected by the detector is out of the second angle range. In the second display control, the display is switched from the sleep state to the active state even when the newly detected direction of the display surface is out of the first angle range.

Abstract: If a customer has picked up a product from a display shelf, a display device displays first sales promotion information. In an information providing system, if the customer has not been attracted to the product and has returned the product to the display shelf, the display device displays second sales promotion information, which is different from the first sales promotion information. By displaying the different pieces of sales promotion information using the display device provided near the product, it is possible to promote the product to the customer in two different ways, thereby stimulating the customer's desire to buy the product and reducing loss in opportunities to sell the product.
