The present disclosure relates to an apparatus and method for displaying information, a program, and a communication system, which enable the provision of an apparatus making use of a display device excellent in flexibility. An information display apparatus includes a display unit including a time information presenting section for presenting at least time information and a band section to be worn on an arm, and a display control unit for changing a display of the display unit. The present disclosure can be applied to, for example, the information display apparatus.

A sequential displaying method is provided. The method includes providing a display device which includes a first display area. The first display area has N first sub-areas that are arranged in sequence, wherein N is positive integer. Then, displayed images in the N first sub-areas are sequentially updated, wherein a time interval of updating the displayed images in two adjacent first sub-areas is 60/N seconds and a frequency for updating a displayed image in each of the first sub-areas is once every 60 seconds. Thus, a method for displaying time information could be improved.

Smart watches and associated systems and methods thereof for lock-screen management are disclosed. A smart watch includes a heart rate sensor, and a method for lock-screen management of the smart watch includes: reading, by the heart rate sensor, a heart rate; determining based on the heart rate whether the smart watch has been taken off by the user, and if yes, stopping the heart rate sensor from working and entering by the smart watch a password-lock-screen mode. Thus, using the method according to the present disclosure can improve the information security on the smart watch.

Past and future time visualization enables a user to visualize the amount of time that has passed or when a future time will be reached. By triggering past time visualization, a device displays an arced line from a previously selected time to the present time. By triggering future time visualization, a device displays an arced line from the present time to a selected future time. In some embodiments, when the future time is reached, an alarm is triggered.

An information display method includes recognizing a position relationship between a dial and an indicating hand from an image in which an electronic timepiece having a dial and an indicating hand for indicating the dial is included as an imaged subject, specifying a value corresponding to the position relationship, based on specification information of the electronic timepiece, and displaying an annotation image relating to the specified value along with the image.

A display device includes a display having a first area and a second area, a counter configured to count a number of steps of a user during walking, and a processor configured to alternately turn on display of the first area and display of the second area in a case where the number of steps of the user during walking is being counted by the counter.

An electronic timepiece includes a display section capable of displaying reception state information based on the strength of a received satellite signal or the number of captured satellites during the execution of a reception process. In a case where a predetermined period has elapsed with no acquisition of time information or position information since the reception process started, the reception state information is displayed on the display section, and in a case where the time information or the position information has been successfully acquired within the predetermined period since the reception process started, the reception state information is not displayed on the display section but the reception process is terminated.

An annular electronic device, including at least two curved sections which are connected into a ring, wherein each curved section includes a processing chip and a display panel, in which the display panel is disposed on an external surface of the curved section, and the processing chip is connected with the display panel. The display area of the annular electronic device is adjustable, and can prolong the service life thereof to a certain degree.
