CROSS-REFERENCE TO RELATED APPLICATION

This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2019-0060869 filed on May 23, 2019, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.

BACKGROUND

Technical Field

The disclosure relates to an electronic device for providing feedback corresponding to an input for a housing.

Description of Related Art

As electronic devices, such as robots for industry and robots for daily use, are increasingly used, the electronic device may provide a user with various services.

For example, the electronic device may provide services, such as guide, education, advertising, and security, in addition to factory automation service in which a given task is performed in place of a worker.

A robot for daily use may provide various types of feedback in response to an input from an electronic device user. For example, the electronic device may receive a user's input through an interface (e.g., display, microphone or button) and provide the user with feedback (e.g., execution of a response or operation) for the received input.

If a surface of the housing of an electronic device (e.g., robot) is made of a rigid material, a user's input may be restricted. For example, the electronic device may receive a voice input from a user or a touch input for a fixed area and provide corresponding feedback.

On the other hand, if a surface of the housing of an electronic device is made of a flexible material, a sensor may show given performance because there is a variation in the mounting of the sensor. For example, if a surface of the housing of an electronic device is made of a flexible material, the electronic device may malfunction or may not provide results expected by a user because the electronic device does not clearly identify the user's input.

SUMMARY

Embodiments of the disclosure may provide an electronic device capable of receiving accurate and various inputs and providing various types of feedback to a user by configuring a surface of a housing using a flexible material and detecting a signal, input to the housing, using, for example, a distance measurement sensor.

FIGS. 8A, 8B and 8C are diagrams illustrating an example of feedback based on a depth change for an input for some area of the housing of the electronic device according to various embodiments of the disclosure.

Referring to FIG. 8A, a depth change of the housing 221 may be changed based on a user's touch and pressing of the electronic device 200. For example, a depth change of the housing 221 may be changed by about 10 mm to 30 mm in response to a touch and pressing pressure applied to the first area 401. According to various embodiments, the electronic device 200 may include the at least one distance measurement sensor 260 within the housing 221. The distance measurement sensor 260 may transmit a given signal (e.g., light, infrared rays or an ultrasonic signal) to at least some area of the housing 221 at given periods using the light-emitting unit 261. When an input occurs in at least some area of the housing 221, the distance measurement sensor 260 may detect a given signal reflected and returned from at least some area of the housing 221 in which the input has occurred through the light-receiving unit 263. According to an example embodiment, when an input (e.g., pressing) occurs in the first area 401 of the housing 221 by a user, the first sensor 301 may detect a depth change (e.g., pressing intensity) by detecting a signal reflected and returned due to the deformation of the first area 401. For example, if an input (e.g., pressing) for the first area 401 of the housing 221 is about 10 mm or about 15 mm, the first sensor 301 may identify that a depth change for the input of about 15 mm is greater than a depth change for the input of about 10 mm.

Referring to FIG. 8B, when a depth change for an input (e.g., pressing) for the first area 401 of the housing 221 is about 10 mm to 15 mm, the electronic device 200 may provide positive feedback. For example, when a depth change for an input (e.g., pressing) for the first area 401 of the housing 221 is about 10 mm to 15 mm, the distance measurement sensor 260 may detect a detection signal for the first area 401 in which the pressing has occurred through the first sensor 301. The detected signal may be transmitted to the first processor 330 through the second processor 340. The first processor 330 may display positive feedback, such as a smiling expression (e.g., Λ Λ), on the display 211 of the head unit 210 based on the detection signal for the first area 401. The first processor 330 may output a sound related to the positive feedback through the sound output unit 280. The first processor 330 may output vibration related to the positive feedback through the vibration output unit 290.

Referring to FIG. 8C, when a depth change for an input (e.g., pressing) for the first area 401 of the housing 221 is about 20 mm to 25 mm, the electronic device 200 may provide negative feedback. For example, when a depth change for an input (e.g., pressing) for the first area 401 of the housing 221 is about 20 mm to 25 mm, the first sensor 301 corresponding to the first area 401 may detect an input signal for the first area 401 in which the pressing has occurred. The detected signal may be transmitted to the first processor 330 through the second processor 340. The first processor 330 may move the head unit 210 in a given direction based on the detection signal for the first area 401 so that the head unit 210 creates a tilting scene. The first processor 330 may display, on the display 211 of the head unit 210, negative feedback such as a surprised expression (e.g., O<). The first processor 330 may output a sound related to the negative feedback through the sound output unit 280. The first processor 330 may output vibration related to the negative feedback through the vibration output unit 290.

FIG. 9 is a diagram illustrating an example of feedback corresponding to an input for at least some area of the housing of the electronic device according to various embodiments of the disclosure.

Referring to FIG. 9, the electronic device 200 may provide feedback corresponding to a user's repetitive input (e.g., a touch and press) for the housing 221.

According to an example embodiment, when a repetitive input (e.g., tap) having a depth change of about 5 mm to 7 mm for the first area 401 of the housing 221 occurs, the first sensor 301 corresponds to the first area 401 may detect an input signal for the first area 401 in which the tap has occurred. The detected signal may be transmitted to the first processor 330 through the second processor 340. The first processor 330 may display feedback, such as (O O), on the display 211 of the head unit 210 based on the detection signal for the first area 401. The first processor 330 may output a sound related to the feedback through the sound output unit 280. The first processor 330 may output vibration related to the feedback through the vibration output unit 290.

According to an example embodiment, when a user's input (e.g., a touch and press) occurs near a place between the first area 401 and second area 402 of the housing 221, the electronic device 200 may detect a depth change for the first area 401 and the second area 402. The electronic device 200 may detect an input signal for the first area 401 and the second area 402 in which the user's input has occurred using the first sensor 301 and the second sensor 302. The detected signal may be transmitted to the first processor 330 through the second processor 340. The first processor 330 may provide feedback, such as various displays, sounds and/or vibration, based on the detection signal for the first area 401 and the second area 402.

FIG. 10 is a diagram illustrating an example of feedback corresponding to a signal detected by a plurality of distance measurement sensors of the electronic device according to various embodiments of the disclosure.

Referring to FIG. 10, a user may perform a plurality of inputs (e.g., a hug behavior or a two-hand pressing behavior) on the housing 221 of the electronic device 200. A plurality of sensors of the first sensor 301 to eighth sensor 308 of the electronic device 200 may detect an input signal (e.g., depth change) for at least some area (e.g., the first area 401 to the eighth area 408) of the housing 221.

According to an example embodiment, when a user of the electronic device 200 performs a plurality of inputs (e.g., a hug behavior) on the housing 221, a depth change of about 5 mm or more for the housing 221 may be maintained for about 1 second to about 5 seconds in a plurality of areas (e.g., at least two or more areas of the first area 401 to the eighth area 408). For example, when a user of the electronic device 200 performs a plurality of inputs (e.g., a hug behavior) on the housing 221, a depth change may occur in at least two or more areas between the first area 401 to fifth area 405 of the housing 221, at least two or more areas between the second area 402 to sixth area 406 of the housing 221, at least two or more areas between the third area 403 to seventh area 407 of the housing 221, and at least two or more areas between the fourth area 304 to eighth area 408 of the housing 221. The first sensor 301 to the fifth sensor 305, the second sensor 302 to the sixth sensor 306, the third sensor 303 to the seventh sensor 307, and the fourth sensor 304 to the eighth sensor 308 may detect respective input signals based on depth changes of the respective areas of the housing 221.

According to an example embodiment, when a user of the electronic device 200 performs a plurality of inputs (e.g., a hug behavior) on the housing 221, depth changes may occur in all of the first area 401 to the eighth area 408. The first sensor 301 to the eighth sensor 308 may detect input signals based on depth changes of the first area 401 to eighth area 408 of the housing 221.

According to an example embodiment, when a user of the electronic device 200 performs a plurality of inputs (e.g., a hug behavior) on the housing 221, the electronic device 200 may detect depth changes in all of the first area 401 to the eighth area 408 through the first sensor 301 to the eighth sensor 308, and may identify the location of the user based on the depth changes. For example, when a user hugs the electronic device 200 at the back of the electronic device 200, the electronic device 200 may rotate the head unit 210 backward.

FIG. 11 is a diagram illustrating an example of feedback corresponding to a user input that modifies the housing of the electronic device according to various embodiments of the disclosure.

According to an example embodiment, when a plurality of inputs (e.g., a hug behavior) is performed on the housing 221, the electronic device 200 may output feedback (e.g., vibration or a sound pattern) similar to the heart beat of a user.

According to an example embodiment, if a depth change occurs because a user of the electronic device 200 performs an input (e.g., hug behavior) on at least some area (e.g., the first area 401 to the eighth area 408) of the housing 221, at least some sensor (e.g., the first sensor 301 to the eighth sensor 308) may detect an input signal for the area where the depth change has occurred. The detected signal may be transmitted to the first processor 330 through the second processor 340. The first processor 330 may provide the same feedback (e.g., vibration pattern) as a heartbeat waveform, for example, using the vibration output unit 290 based on the detected signal.
