Abstract

A wearable device according to an example of embodiments includes a display unit configured to display characters, a detector configured to detect a user'"'"'s upper limb existing in a real space, and a controller. When a first body motion of allowing one part and the other part of the upper limb to approach each other is detected from a detection result of the detector, the controller executes a character selection process of selecting the characters. The wearable device is attachable to the head.

Claims

1. A wearable device attachable to a head, the wearable device comprising:

a display unit configured to display characters;

a detector configured to detect a user'"'"'s upper limb existing in a real space; and

a controller configured to,

in response to the detector detecting a single first body motion causing one part and the other part of the upper limb to approach each other,

select a character string from the characters displayed by the display unit, the character string being defined by positions of the one part and the other part of the upper limb when the single first body motion begins, wherein the character string is editable text,

wherein, when the first body motion is detected, and it is detected that a moving speed of the one part or the other part in the first body motion is equal to or higher than a first speed, the controller is configured to execute a character selection process of selecting the character string.

2. The wearable device according to claim 1, wherein the controller calculates an angle at which the direction in which the one part and the other part of the upper limb approach each other and an input direction of the character intersect each other, and when the angle is equal to or smaller than a first angle, the controller is configured to execute the character selection process of selecting the character string.

3. The wearable device according to claim 1, wherein the controller calculates an angle at which the direction in which the one part and the other part of the upper limb approach each other and a direction perpendicular to an input direction of the character intersect each other, and when the angle is equal to or smaller than a second angle, the controller is configured to execute the character selection process of selecting the character string.

4. The wearable device according to claim 1,

wherein the display unit is configured to display a character string, and

wherein, when the first body motion is detected, the controller is configured to execute the character selection process of selecting the character string on the number of the characters defined by a position of the one part and a position of the other part that are immediately before the first body motion is detected in the character string.

5. The wearable device according to claim 1,

wherein the display unit is configured to display a character string configured with a plurality of lines, and

wherein, when the first body motion is detected, the controller is configured to execute the character selection process of selecting the character string on the character string having the number of lines defined by a position of the one part and a position of the other part that are immediately before the first body motion is detected in the character strings.

6. The wearable device according to claim 1,

wherein the controller is configured to execute a character type changing process of changing a character type of the characters when a body motion accompanying a change in a distance between one part and the other part of the upper limb is detected from a detection result of the detector,

wherein the character type changing process is a process of changing one to the other of two predetermined character types,

wherein, when the first body motion of allowing the distance between the one part and the other part of the upper limb to decrease is detected, the controller is configured to change the one to the other, and

wherein, when a second body motion of allowing the distance between the one part and the other part of the upper limb to increase is detected, the controller is configured to change the other to the one.

7. The wearable device according to claim 6,

wherein the two types of characters are types of characters having a predetermined magnitude relationship with each other,

wherein, when the first body motion is detected, one that is relatively large is changed to the other that is relatively small out of the two types of character, and

wherein, when the second body motion is detected, one that is relatively small is changed to the other that is relatively large out of the two types of character.

8. A control method executed by a wearable device that is attachable to a head and includes a display unit configured to display characters, a detector configured to detect a user'"'"'s upper limb existing in a real space, and a controller, the method comprising:

in response to the detector detecting a single first body motion causing one part and the other part of the upper limb to approach each other,

selecting, by the controller, a character string from the characters displayed by the display unit, the character string being defined by positions of the one part and the other part of the upper limb when the single first body motion begins, wherein the character string is editable text,

wherein,

the controller calculates an angle at which the direction in which the one part and the other part of the upper limb approach each other and an input direction of the character intersect each other, and

when the angle is equal to or smaller than a first angle, the controller executes a character selection process of selecting the character string.

9. A non-transitory computer readable recording medium recording therein a control program executable in a wearable device that is attachable to a head and includes a display unit configured to display characters, a detector configured to detect a user'"'"'s upper limb existing in a real space, and a controller,

wherein,

in response to the detector detecting a single first body motion causing one part and the other part of the upper limb to approach each other,

the control program causes the controller to select a character string from the characters displayed by the display unit, the character string being defined by positions of the one part and the other part of the upper limb when the single first body motion begins, wherein the character string is editable text,

the control program causes the controller to calculate an angle at which the direction in which the one part and the other part of the upper limb approach each other and a direction perpendicular to an input direction of the character intersect each other, and

when the angle is equal to or smaller than a second angle, the control program causes the controller to execute a character selection process of selecting the character string.
