Methods and apparatus for receiving, converting into text, and verifying user gesture input from an information input device

1. An information input device comprising:

a display unit configured to display a user interface for acknowledging user input information in a content including an input field displayed on a screen, by accepting an operation on the screen, the user interface being displayed by way of at least a gesture input area and a verification field, separate from the gesture input area, each defined by translucent border lines that appear superimposed in front of the content, and where the gesture input area includes a transparent region that overlies the input field;

a converter unit configured to analyze the user input information received within the transparent region of the gesture input area and to recognize that the user input information represents one or more characters of one or more languages, where the gesture input area is a significantly larger area than an area of the input field; and

a transcription unit configured to provide, in the input field in the content, the one or more characters from the user input information acknowledged in the user interface, wherein:

the display unit displays: (i) the user input information in the transparent region of the gesture input area such that the user input information overlies the input field, and (ii) the one or more characters in the verification field of the user interface, in a size larger than in the input field, where the verification field allows the user to verify the one or more characters recognized from the user input information provided in the gesture input area,

the display unit permits the user to edit the one or more characters in the verification field using text input keys in order to change and accept the one or more characters, and

the transcription unit updates the one or more characters to the changed one or more characters in the input field in the content.

2. The input information device according to one of claim 1 , wherein the transcription unit provides, when the user input information is acknowledged in the user interface, the acknowledged user input information in the input field in the content as needed without waiting for a user command requesting the input information to be provided in the input field.

3. The information input device according to claim 1 , wherein the display unit renders the user interface using a color complementary to a color provided in the content so that the user can easily distinguish between the user interface and the content that represents a background.

4. The information input device according to claim 3 , wherein the display unit determines a color of a specified pixel showing at least part of the user interface such that a pixel in the content corresponding to the specified pixel is identified and a color complementary to a color provided in the pixel identified as corresponding is provided as the color of the specified pixel.

5. The information input device according to claim 4 , wherein, when the display unit identifies a corresponding pixel in the content, the display unit also identifies surrounding pixels located around the corresponding pixel and determines a color complementary to a color obtained by averaging colors of the corresponding pixel and the surrounding pixels as being the color of the specified pixel.

6. The information input device according to one of claim 1 , wherein the display unit identifies brightness of a color provided in the content and renders the user interface using a color obtained by changing the identified brightness by a predetermined amount, so that the user can easily distinguish between the user interface and the content that represents a background.

7. The information input device according to one of claim 1 , further comprising a command unit configured to allow the user to select information input via the user interface instead of directly entering information in the input field in the content.

8. The information input device of claim 1 , wherein the display unit displays the user input information in the gesture input area such that: (i) a first gesture is rendered in the gesture input area at a first translucence; and (ii) thereafter a second gesture is rendered in the gesture input area at the first translucence, whereby the first gesture is re-rendered at a second translucence, fainter than the first translucence.

9. An information input method comprising:

displaying a user interface for acknowledging user input information in a content including an input field displayed on a screen, by accepting an operation on the screen, the user interface being displayed by way of at least a gesture input area and a verification field, separate from the gesture input area, each defined by translucent border lines that appear superimposed in front of the content, and where the gesture input area includes a transparent region that overlies the input field;

analyzing the user input information received within the transparent region of the gesture input area and to recognize that the user input information represents one or more characters of one or more languages, where the gesture input area is a significantly larger area than an area of the input field;

providing, in the input field in the content, the one or more characters from the user input information acknowledged in the user interface;

displaying: (i) the user input information in the transparent region of the gesture input area such that the user input information overlies the input field, and (ii) the one or more characters in the verification field of the user interface, in a size larger than in the input field, where the verification field allows the user to verify the one or more characters recognized from the user input information provided in the gesture input area;

permitting the user to edit the one or more characters in the verification field using text input keys in order to change and accept the one or more characters; and

updating the one or more characters to the changed one or more characters in the input field in the content.

10. The information input method of claim 9 , wherein the displaying step includes displaying the user input information in the gesture input area such that: (i) a first gesture is rendered in the gesture input area at a first translucence; and (ii) thereafter a second gesture is rendered in the gesture input area at the first translucence, whereby the first gesture is re-rendered at a second translucence, fainter than the first translucence.

11. A non-transitory computer-readable recording medium containing a program, the program comprising:

a module configured to display a user interface for acknowledging user input information in a content including an input field displayed on a screen, by accepting an operation on the screen, the user interface being displayed by way of at least a gesture input area and a verification field, separate from the gesture input area, each defined by translucent border lines that appear superimposed in front of the content, and where the gesture input area includes a transparent region that overlies the input field;

a module configured to analyze the user input information received within the transparent region of the gesture input area and to recognize that the user input information represents one or more characters of one or more languages, where the gesture input area is a significantly larger area than an area of the input field; and

a module configured to provide, in the input field in the content, the one or more characters from the user input information acknowledged in the user interface, wherein:

the module configured to display: (i) displays the user input information in the transparent region of the gesture input area such that the user input information overlies the input field, and (ii) displays the one or more characters in the verification field of the user interface, in a size larger than in the input field, where the verification field allows the user to verify the one or more characters recognized from the user input information provided in the gesture input area,

the module configured to display permits the user to edit the one or more characters in the verification field using text input keys in order to change and accept the one or more characters, and
