Abstract
There is provided a mobile terminal device designed to perform wireless communication with an RFID tag being held over the device by using electromagnetic waves. The device includes a plurality of antennae arranged in or in vicinity to a display area of the mobile terminal device, and a control unit configured to detect a part of the display area, which is not covered with the RFID tag, from electromagnetic wave intensities acquired by the plurality of antennae and to display information for a user in the detected part of the display area.
Claims9
A mobile terminal device designed to perform wireless communication with an RFID tag being held over the mobile terminal device by using electromagnetic waves, the mobile terminal device comprising:
- a plurality of antennae arranged in or in vicinity to a display area of the mobile terminal device;
- and
- a control unit configured to detect a part of the display area which is not covered with the RFID tag, from electromagnetic wave intensities acquired by the plurality of antennae and to display information for a user in the detected part of the display area which is not covered with the RFID tag,
- wherein the control unit is further configured to:
- determine whether or not the RFID tag is held over the mobile terminal device,
- compare electromagnetic wave intensities acquired by the plurality of antennae when it is determined that the RFID tag is being held over the mobile terminal device,
- specify the part of the display area which is not covered with the RFID tag, of an entire display area of the mobile terminal device, based on a comparison result,
- calculate a ratio of the part of the display area which is not covered with the RFID tag to the display area,
- display the information on a display position in the specified part of the display area which is not covered with the RFID tag when it is determined that the calculated ratio is greater than a predetermined value, and
- notifies the user by sound, light, or vibration if the calculated ratio is less than or equal to the predetermined value.
A non-transitory computer-readable program storage medium which stores a program to be executed by a computer within a mobile terminal device having a plurality of antennae arranged in or in vicinity to a display area of the mobile terminal device and designed to perform wireless communication with an RFID tag being held over the mobile terminal device by using electromagnetic waves, the program comprising:
- detecting a part of the display area which is not covered with the RFID tag, from electromagnetic wave intensities acquired by the plurality of antennae;
- and
- displaying information for a user in the detected part of the display area which is not covered with the RFID tag,
- wherein the program further comprises:
- determining whether or not the RFID tag is held over the mobile terminal device,
- comparing electromagnetic wave intensities acquired by the plurality of antennae when it is determined that the RFID tag is being held over the mobile terminal device,
- specifying the part of the display area which is not covered with the RFID tag, of an entire display area of the mobile terminal device, based on a comparison result,
- calculating a ratio of the part of the display area which is not covered with the RFID tag to the entire display area, and
- displaying the information on a display position in the specified part of the display area which is not covered with the RFID tag when it is determined that the calculated ratio is greater than a predetermined value, and
- notifying the user by sound, light, or vibration if the calculated ratio is less than or equal to the predetermined value.
An information displaying method for use in a mobile terminal device having a plurality of antennae arranged in or in vicinity to a display area of the mobile terminal device and designed to perform wireless communication with an RFID tag being held over the mobile terminal device by using electromagnetic waves, the method comprising:
- detecting a part of the display area which is not covered with the RFID tag, from electromagnetic wave intensities acquired by the plurality of antennae;
- and
- displaying information for a user in the detected part of the display area which is not covered with the RFID tag,
- wherein the method further comprises:
- determining whether or not the RFID tag is held over the mobile terminal device,
- comparing electromagnetic wave intensities acquired by the plurality of antennae when it is determined that the RFID tag is being held over the mobile terminal device,
- specifying the part of the display area which is not covered with the RFID tag, of an entire display area of the mobile terminal device, based on a comparison result,
- calculating a ratio of the part of the display area which is not covered with the RFID tag to the entire display area, and
- displaying the information on a display position in the specified part of the display area which is not covered with the RFID tag when it is determined that the calculated ratio is greater than a predetermined value, and
- notifying the user by sound, light, or vibration if the calculated ratio is less than or equal to the predetermined value.
