Indicating potential focus in a user interface
Methods and apparatus, including computer program products, implementing and using techniques for an integrated user interface an interface that receives user input through the user interface. Output is provided through the user interface, and all user input received through the user interface is interpreted as explicitly being separated input into one of three classes, namely, pointing input, content input, and command input.
1. A method performed by an information appliance, the method comprising:
receiving a verb-text input from a user and displaying the received verb-text in a user interface of the information appliance, wherein the information appliance is operable to invoke a plurality of commands in response to receiving command input from the user, and wherein receiving the verb-text input is not associated with any of the plurality of commands;
receiving a user input selecting a portion of the displayed verb-text;
after receiving the user input selecting the portion of the displayed verb-text, receiving a command input from the user that designates the displayed verb-text input as being command text;
after receiving the command input, selecting a first command from the plurality of commands according to the command text;
receiving a noun-text input from the user and displaying the received noun-text in the user interface, wherein receiving the noun-text input is not associated with any of the plurality of commands; and
invoking the first command, wherein the first command uses the displayed noun-text as an operand.
2. The method of claim 1 , further comprising:
after receiving the command input and before invoking the first command, receiving an input from the user identifying the displayed noun-text.
3. The method of claim 2 , wherein the command input is a tap of a command key by the user, and wherein the command key is a designated control that, when tapped by a user, indicates that a current selection of displayed text is to be interpreted by the information appliance as command input.
4. The method of claim 1 , further comprising:
receiving an input from the user activating a command quasimode;
receiving the verb-text input from the user while the command quasimode is activated; and
selecting the first command after receiving an input from the user deactivating the command quasimode.
5. The method of claim 4 , wherein a command quasimode is defined by the user activating and holding a control that indicates that other input submitted by the user while the control is held is to be interpreted by the information appliance as command input.
6. The method of claim 4 , wherein the user input activating the command quasimode is a press of a command key by the user and the user input deactivating the command quasimode is a release of the command key by the user.
7. The method of claim 4 , further comprising:
displaying the verb-text input in a transparent message box in the user interface while the command quasimode is activated.
8. The method of claim 1 , further comprising:
deleting the displayed verb-text after invoking the first command.
9. An information appliance apparatus comprising:
one or more processors and one or more storage devices storing instructions that when executed by the one or more processors cause the one or more processors to perform operations comprising:
receiving a verb-text input from a user and displaying the received verb-text in a user interface of the information appliance apparatus, wherein the information appliance apparatus is operable to invoke a plurality of commands in response to receiving command input from the user, and wherein receiving the verb-text input is not associated with any of the plurality of commands;
receiving a user input selecting a portion of the displayed verb-text;
after receiving the user input selecting the portion of the displayed verb-text, receiving a command input from the user that designates the displayed verb-text input as being command text;
after receiving the command input, selecting a first command from the plurality of commands according to the command text;
receiving a noun-text input from the user and displaying the received noun-text in the user interface, wherein receiving the noun-text input is not associated with any of the plurality of commands; and
invoking the first command, wherein the first command uses the displayed noun-text as an operand.
10. The information appliance apparatus of claim 9 , the operations further comprising:
after receiving the command input and before invoking the first command, receiving an input from the user identifying the displayed noun-text.
11. The information appliance apparatus of claim 10 , wherein the command input is a tap of a command key by the user, and wherein the command key is a designated control that, when tapped by a user, indicates that a current selection of displayed text is to be interpreted by the information appliance as command input.
12. The information appliance apparatus of claim 9 , the operations further comprising:
receiving an input from the user activating a command quasimode;
receiving the verb-text input from the user while the command quasimode is activated; and
selecting the first command after receiving an input from the user deactivating the command quasimode.
13. The information appliance apparatus of claim 12 , wherein a command quasimode is defined by the user activating and holding a control that indicates that other input submitted by the user while the control is held is to be interpreted by the information appliance as command input.
14. The information appliance apparatus of claim 12 , wherein the user input activating the command quasimode is a press of a command key by the user and the user input deactivating the command quasimode is a release of the command key by the user.
15. A computer storage medium encoded with a computer program, the program comprising instructions that when executed by an information appliance cause the information appliance to perform operations comprising:
receiving a verb-text input from a user and displaying the received verb-text in a user interface of the information appliance, wherein the information appliance is operable to invoke a plurality of commands in response to receiving command input from the user, and wherein receiving the verb-text input is not associated with any of the plurality of commands;
receiving a user input selecting a portion of the displayed verb-text;
after receiving the user input selecting the portion of the displayed verb-text, receiving a command input from the user that designates the displayed verb-text input as being command text;
after receiving the command input, selecting a first command from the plurality of commands according to the command text;
receiving a noun-text input from the user and displaying the received noun-text in the user interface, wherein receiving the noun-text input is not associated with any of the plurality of commands; and
invoking the first command, wherein the first command uses the displayed noun-text as an operand.
16. The computer storage medium of claim 15 , the operations further comprising:
after receiving the command input and before invoking the first command, receiving an input from the user identifying the displayed noun-text.
17. The computer storage medium of claim 16 , wherein the command input is a tap of a command key by the user, and wherein the command key is a designated control that, when tapped by a user, indicates that a current selection of displayed text is to be interpreted by the information appliance as command input.
18. The computer storage medium of claim 15 , the operations further comprising:
receiving an input from the user activating a command quasimode;
receiving the verb-text input from the user while the command quasimode is activated; and
selecting the first command after receiving an input from the user deactivating the command quasimode.
19. The computer storage medium of claim 18 , wherein a command quasimode is defined by the user activating and holding a control that indicates that other input submitted by the user while the control is held is to be interpreted by the information appliance as command input.
20. The computer storage medium of claim 18 , wherein the user input activating the command quasimode is a press of a command key by the user and the user input deactivating the command quasimode is a release of the command key by the user.
