Display apparatus and non-transitory computer readable medium for preventing execution of processing unrelated to situation of preparation of processing
A display apparatus include: a displayer that displays on a screen at least one image used for an operation to instruct execution of processing under a predetermined condition; a preparation detector that detects preparation performed by a user for the processing; and a disabling unit that disables a non-target image used for an operation to instruct execution of non-target processing different from target processing corresponding to a result of detection of the preparation detector, the non-target image being of the at least one image displayed on the screen.
1. A display apparatus comprising:
a displayer that displays on a screen at least one image used for an operation to instruct execution of processing under a predetermined condition;
a preparation detector that detects preparation performed by a user for the processing, wherein the preparation comprises supplying objects or data required for processing to the display apparatus by an operation or an activity of the user; and
a disabling unit that disables a non-target image used for an operation to instruct execution of non-target processing different from target processing corresponding to a result of detection of the preparation detector, the non-target image being of the at least one image displayed on the screen, wherein the at least one image includes a target image used for an operation to instruct execution of the target processing, and the non-target image, and the disabling unit disables an operation of the target image and the non-target image while the screen is scrolled by an operation of the user.
2. The display apparatus according to claim 1 ,
wherein the disabling unit disables an operation using the non-target image.
3. The display apparatus according to claim 2 ,
wherein the at least one image includes a target image used for an operation to instruct execution of the target processing, and the non-target image, and
the disabling unit causes the non-target image to be displayed distinctively from the target image.
4. The display apparatus according to claim 3 ,
wherein the at least one image includes a target image used for an operation to instruct execution of the target processing, and the non-target image, and
the display apparatus further comprises:
an operation detector that detects a situation of operations of the user until an operation using the target image is performed; and
a processing controller that changes steps until the target processing is executed, according to the operation using the target image of the at least one image displayed on the screen, based on the situation of the operations detected by the operation detector.
5. The display apparatus according to claim 2 ,
wherein the at least one image includes a target image used for an operation to instruct execution of the target processing, and the non-target image, and
the display apparatus further comprises:
an operation detector that detects a situation of operations of the user until an operation using the target image is performed; and
a processing controller that changes steps until the target processing is executed, according to the operation using the target image of the at least one image displayed on the screen, based on the situation of the operations detected by the operation detector.
6. The display apparatus according to claim 1 ,
wherein the disabling unit controls display of the non-target image to achieve a state in which the non-target image does not accept an operation.
7. The display apparatus according to claim 6 ,
wherein the disabling unit, after displaying a message indicating that the non-target image is hidden, hides the non-target image.
8. The display apparatus according to claim 7 ,
wherein the at least one image includes a target image used for an operation to instruct execution of the target processing, and the non-target image, and
the display apparatus further comprises:
an operation detector that detects a situation of operations of the user until an operation using the target image is performed; and
a processing controller that changes steps until the target processing is executed, according to the operation using the target image of the at least one image displayed on the screen, based on the situation of the operations detected by the operation detector.
9. The display apparatus according to claim 6 ,
wherein the at least one image includes a target image used for an operation to instruct execution of the target processing, and the non-target image, and
the display apparatus further comprises:
an operation detector that detects a situation of operations of the user until an operation using the target image is performed; and
a processing controller that changes steps until the target processing is executed, according to the operation using the target image of the at least one image displayed on the screen, based on the situation of the operations detected by the operation detector.
10. The display apparatus according to claim 1 ,
wherein the at least one image includes a target image used for an operation to instruct execution of the target processing, and the non-target image, and
the display apparatus further comprises:
an operation detector that detects a situation of operations of the user until an operation using the target image is performed; and
a processing controller that changes steps until the target processing is executed, according to the operation using the target image of the at least one image displayed on the screen, based on the situation of the operations detected by the operation detector.
11. The display apparatus according to claim 10 ,
wherein the situation of the operations is an elapsed time or a number of operations of scrolling the screen until the operation using the target image is performed since the preparation is detected by the preparation detector and
when the elapsed time or the number of the operations satisfies a predetermined condition, the processing controller accepts another operation to instruct start of the processing, then starts the target processing.
12. The display apparatus according to claim 1 , wherein the at least one image includes a target image used for an operation to instruct execution of the target processing, and the non-target image, and the display apparatus further comprises: an operation detector that detects a situation of operations of the user until an operation using the target image is performed; and a processing controller that changes steps until the target processing is executed, according to the operation using the target image of the at least one image displayed on the screen, based on the situation of the operations detected by the operation detector.
13. A non-transitory computer readable medium storing a program causing a computer to execute a process comprising: displaying on a screen at least one image used for an operation to instruct execution of processing under a predetermined condition;
detecting preparation performed by a user for the processing, wherein the preparation comprises supplying objects or data required for processing to the computer by an operation or an activity of the user; and disabling a non-target image used for an operation to instruct execution of non-target processing different from target processing corresponding to a result of detection of the preparation, the non-target image being of the at least one image displayed on the screen, wherein the at least one image includes a target image used for an operation to instruct execution of the target processing, and the non-target image, and disabling an operation of the target image and the non-target image while the screen is scrolled by an operation of the user.
