Information processing apparatus and operation control method
View Patent ↗According to one embodiment, an information processing apparatus includes a state change controller and a display processor. When a first key of a keyboard is pressed, the state change controller changes a state of a first operational environment. The display processor displays a first message indicative of a current state of the first operational environment in an informing area of a display screen for a first duration of time. When a second message indicative of a past state of the first operational environment is displayed by the display processor for the first duration of time in the informing area, the display processor display the first message in the informing area together with the second message.
1. An information processing apparatus comprising:
a keyboard;
a state change controller configured to change, when a first key of the keyboard is pressed, a state of a first operational environment of the information processing apparatus; and
a display processor configured to display a first message indicative of a current state of the first operational environment in an informing area of a display screen for a first duration of time, and when a second message indicative of a past state of the first operational environment is displayed by the display processor for the first duration of time in the informing area, the display processor is further configured to display the first message in the informing area together with the second message.
2. The apparatus of claim 1 , wherein the display processor is further configured to remove the first message when the first duration of time elapses after start of display of the first message, and remove the second message when the first duration of time elapses after start of display of the second message.
3. The apparatus of claim 1 , wherein the display processor is further configured to fade out the first message such that the first message disappears when the first duration of time elapses after start of display of the first message, and fade out the second message such that the second message disappears when the first duration of time elapses after start of display of the second message.
4. The apparatus of claim 3 , wherein the display processor is further configured to fade out the first message such that a color of the first message continuously becomes lighter, and fade out the second message such that a color of the second message continuously becomes lighter.
5. The apparatus of claim 1 , wherein the display processor is further configured to display the first message in the informing area such that the first message and the second message are stacked each other.
6. The apparatus of claim 1 , wherein the first operational environment is an operational environment associated with one of a power-saving setting of the information processing apparatus, an enabled/disabled state of a touch pad of the information processing apparatus, an ON/OFF state of a wireless communication device of the information processing apparatus, and an ON/OFF state of a keyboard backlight of the information processing apparatus.
7. The apparatus of claim 1 , wherein
when a second key of the keyboard is pressed, the state change controller is configured to change a second operational environment of the information processing apparatus, and
when the first message is being displayed in the informing area, the display processor is configured to display a third message indicative of a current state of the second operational environment in the informing area together with the first message for the first duration of time.
8. The apparatus of claim 7 , wherein the first operational environment is an operational environment associated with a power-saving setting of the information processing apparatus, and the second operational environment is an operational environment associated with an ON/OFF state of a keyboard backlight of the information processing apparatus.
9. An operation control method for an information processing apparatus, comprising:
changing, when a first key of a keyboard of the information processing apparatus is pressed, a state of a first operational environment of the information processing apparatus; and
displaying a first message indicative of a current state of the first operational environment in an informing area of a display screen for a first duration of time, wherein
the displaying comprises displaying the first message in the informing area together with a second message, when the second message indicative of a past state of the first operational environment is displayed for the first duration of time in the informing area.
10. A computer-readable, non-transitory storage medium comprising a computer program configured to be executed by a computer, the computer program controlling the computer to execute functions of:
changing, when a first key of a keyboard of the computer is pressed, a state of a first operational environment of the computer; and
displaying a first message indicative of a current state of the first operational environment in an informing area of a display screen for a first duration of time,
the function of displaying comprising displaying the first message in the informing area together with a second message, when the second message indicative of a past state of the first operational environment is displayed for the first duration of time in the informing area.
