Abstract

Systems and methods are provided for detecting a touch of a first key associated with a first character on the keyboard, detecting a touch of a second key corresponding to a second character on the keyboard, determining an order for previewing the first and second characters in response to the detecting, and previewing the first and second characters in the determined order in an information entry field of the electronic device.

Claims

1. A method for operating an electronic device having a physical keyboard with a plurality of physical keys, the physical keyboard capable of detecting a touch of at least one physical key without a depression required for entry of a character associated with the physical key and that meets or exceeds a preview threshold, the method comprising:

detecting a first touch of a first physical key associated with a first character on the physical keyboard without the depression required for entry of the first character and that meets or exceeds the preview threshold;

detecting a second touch of a second physical key corresponding to a second character on the physical keyboard without the depression required for entry of the second character and that meets or exceeds the preview threshold;

determining an order for previewing the first and second characters in response to the detecting, wherein determining the order for previewing the first and second characters comprises using a word prediction engine to identify the word prediction candidate based on the first character, the second character, and the previously-entered characters, wherein the order for previewing the first and second characters is an order of the first and second characters in the word prediction candidate; and

displaying a preview of the first and second characters in the determined order next to previously-entered characters in an information entry field of the electronic device, the previously-entered characters entered with a depression required for entry, the preview of the first and second characters and the previously-entered characters forming a single word prediction candidate.

2. The method of claim 1, wherein the method further comprises:

detecting a third touch of a third physical key associated with a third character on the physical keyboard without the depression required for entry of the third character and that meets or exceeds the preview threshold; and

when the third key is associated with a previously-entered character, ignoring the third character when determining the order for previewing the first and second characters.

3. The method of claim 1, wherein whether the preview threshold is met or exceeded is evaluated on at least one of:

a depression amount of a physical key less than the amount that is required for entry of the character associated with the key; and

a presence on a physical key without a depression of the physical key.

4. The method of claim 1, wherein the preview threshold comprises at least one of a time threshold, a force threshold, an actuation threshold, and a capacitive threshold associated with a touch.

5. An electronic device having a display and a physical keyboard with a plurality of physical keys, the physical keyboard capable of detecting a touch of at least one physical key without a depression required for entry of a character associated with the physical key and that meets or exceeds a preview threshold, comprising:

a memory containing instructions; and

one or more processors configured to execute the instructions to;

detect a first touch of a first physical key associated with a first character on the physical keyboard without the depression required for entry of the first character and that meets or exceeds the preview threshold;

detect a second touch of a second physical key corresponding to a second character on the physical keyboard without the depression required for entry of the second character and that meets or exceeds the preview threshold;

determine an order for previewing the first and second characters in response to the detection, wherein determining the order for previewing the first and second characters comprises using a word prediction engine to identify the word prediction candidate based on the first character, the second character, and the previously-entered characters, wherein the order for previewing the first and second characters is an order of the first and second characters in the word prediction candidate; and

display a preview of the first and second characters in the determined order next to previously-entered characters in an information entry field of the electronic device, the previously-entered characters entered with a depression required for entry, the preview of the first and second characters and the previously-entered characters forming a single word prediction candidate.

6. The electronic device of claim 5, wherein the one or more processors are configured to execute the instructions to:

detect a third touch of a third physical key associated with a third character on the physical keyboard without the depression required for entry of the third character and that meets or exceeds the preview threshold; and

when the third key is associated with a last-entered character, ignore the third character when determining the order for previewing the first and second characters.

7. A non-transitory computer-readable storage medium storing one or more programs, the one or more programs comprising instructions, when executed by a computing device having a physical keyboard with a plurality of physical keys, the physical keyboard capable of detecting a touch of at least one physical key without a depression required for entry of a character associated with the physical key and that meets or exceeds a preview threshold, that cause the device to:

detect a first touch of a first physical key associated with a first character on the physical keyboard without the depression required for entry of the first character and that meets or exceeds the preview threshold;

detect a second touch of a second physical key corresponding to a second character on the physical keyboard without the depression required for entry of the second character and that meets or exceeds the preview threshold;

determine an order for previewing the first and second characters in response to the detection, wherein determining the order for previewing the first and second characters comprises using a word prediction engine to identify the word prediction candidate based on the first character, the second character, and the previously-entered characters, wherein the order for previewing the first and second characters is an order of the first and second characters in the word prediction candidate; and

displaying a preview of the first and second characters in the determined order next to previously-entered characters in an information entry field of the device, the previously-entered characters entered with the depression required for entry, the preview of the first and second characters and the previously-entered characters forming a single word prediction candidate.
