The user can perform operations such as magnifying and highlighting the image displayed on the display screen to assist in reading the text.

[0033] Based on deep learning OCR (Optical Character Recognition) technology and TTS (Text To Speech) technology, it is possible to recognize text in images and convert the recognized text into speech to play to the user. However, to achieve such a function, the chip must be able to support artificial intelligence technologies such as deep learning. However, many electronic visual aids currently do not have built-in chips with corresponding processing capabilities, and it is impossible to enable electronic visual aids that do not originally have these functions to achieve the above functions through software system upgrades, making it difficult for users to expand the functions of electronic visual aids.

[0034] In order to solve the above problems, the present disclosure provides a portable device.

[0035] Figures 1A to 1D A front view, a front view, a left view, and a right view of an example of a portable device according to an embodiment of the present disclosure are shown.

[0036] like Figure 1A As shown, the portable device 100 may include a housing 101, and an opening for arranging a data connection line interface 102 is provided on the housing 101. The housing 101 may be provided with the following Figure 2 The main board 200 ( Figure 1A The mainboard is provided with a processor for performing text recognition on the image and converting the recognized text into voice output. The mainboard may also be provided with components for implementing other functions. The portable device 100 may be removably connected to an electronic device via a data connection line installed in the data connection line interface 102, and obtain a picture from the electronic device via the data connection line, wherein the picture includes text characters.

[0037] In some embodiments, the processor is also configured to recognize objects, human bodies, etc. in the acquired pictures and convert the recognized information into voice output.

[0038] In some embodiments, the portable device 100 may not include an image acquisition device. That is, the portable device 100 itself does not have the function of acquiring images, but has the function of recognizing text in images and converting the recognized text into voice output. Since the arrangement of the image acquisition device is omitted, the portable device has lower power consumption, lower heat generation, and can have a smaller size, so that the user can carry it with him / her.

[0039] In some embodiments, the portable device 100 may not include a display, but may prompt the user of the device operating status or implement other user interactive feedback through other forms such as indicator lights, tactile feedback, or voice feedback, so as to further reduce the power consumption of the portable device, extend the user's usage time, and further reduce the size of the device to facilitate user carrying.

[0040] In some embodiments, a touch pad or a touch screen is provided on the surface of the portable device 100 to further enhance the user's interactive experience.

[0041] In some embodiments, the electronic device to which the portable device is connected via a data connection line may be an electronic device capable of displaying or storing images.

Figure 1D As shown, the data connection line interface 102 is arranged on the side with the smallest area in the housing. Since the portable device needs to obtain pictures from the electronic device through the connection of the data connection line, the above arrangement can reduce the influence of the data connection line on the use of the function keys of the portable device.

[0047] In some examples, the portable device 100 may also include an earphone jack configured to connect an earphone for playing the voice output. When the user is in an environment where it is inconvenient to amplify the sound, the earphone may be used to obtain the voice output.

[0048] In some examples, the portable device 100 may also include a Bluetooth unit for realizing Bluetooth connection with other devices. The device connected via Bluetooth may be an audio playback device (such as a wireless headset, a wireless speaker, etc.), or a device with other functions such as a data storage device. For example, the voice output may be transmitted to another audio playback device via a Bluetooth connection, realizing flexible deployment of the voice output.

[0049] In some examples, the portable device 100 may further include a microphone configured to receive voice input for controlling the portable device. The processor may perform voice recognition on the received voice input and perform corresponding operations according to the voice recognition result. The above method can conveniently provide users with more device control methods without adding physical buttons.

[0050] In some examples, the portable device 100 may further include a battery for powering the portable device 100. Figure 1B As shown, the housing 101 may include a charging interface 105.

[0051] like Figures 1A to 1DAs shown, the portable device 100 may include a plurality of key openings for accommodating physical keys for controlling the portable device. Compared with virtual keys, physical keys can better meet the needs of users with visual impairments. As shown in the figure, the physical keys may include a power key 106, a menu key 107, a progress adjustment key 108, a volume adjustment key 109, and a play / pause key 110. It is understood that those skilled in the art may increase or decrease the number of physical keys according to actual conditions and design the functions of the physical keys according to actual conditions.

[0052] In some examples, the power button 106 may be disposed on a surface with the largest area in a housing of the portable device 100. In an example, a user may power on the portable device by pressing the power button 106.

[0053] like Figure 1A , Figure 1C In the embodiment, the menu key 107, the progress adjustment key 108 and the play / pause key 110 are located on the same surface as the power key 106, and the volume adjustment key 109 is located on a different surface from the power key 106. With the above button arrangement scheme, the user can conveniently locate the menu key 107, the progress adjustment key 108 and the play / pause key 110 which are used more frequently on the same surface as the power key, while the volume adjustment key 109 which is used less frequently can be arranged on another surface.

[0054] When the portable device is connected to the electronic device, in response to the power button being pressed, the text recognition of the picture received from the electronic device is started, and the voice output is automatically generated and played according to the text recognition result. In the case where the portable device has been turned on and connected to the electronic device via a data connection line, the user can start the text recognition and text-to-speech conversion for the picture obtained via the data connection line by pressing the power button 106. The user only needs to press the power button, and the processor will automatically perform the text recognition and text-to-speech operations of the picture, and output the corresponding voice output via a speaker or earphone. Unlike the general portable device power button that is only used for power on and power off functions, the portable device of the embodiment of the present disclosure reuses the power button as a function key that enables voice output, which can save the space occupied by the button on the shell, so that the size of the portable device can be controlled within a smaller range to achieve the effect of convenient carrying. In this case, by arranging the power button 106 on the surface with the largest area in the shell, it is convenient for the user to perform the corresponding operation.

[0055] In some examples, the portable device 100 may further include a motor for generating vibration in response to a physical key being pressed, thereby providing appropriate operational feedback to the user.

[0056] In some examples, the portable device 100 may also include a wireless communication unit for accessing a wireless network via a wireless connection. For example, a wireless access network may be configured for the portable device through a supporting application, and the wireless network may be accessed according to the configuration information. When accessing a wireless network, the portable device may receive required information from the wireless network or upload its own data on the wireless network according to actual conditions. For another example, when it is necessary to upgrade the system in the portable device, a system installation package may be received via a wireless network to upgrade the system of the portable device.

[0057] In some examples, the portable device 100 may further include an indicator light 111 for displaying different colors to indicate different device states. Figure 1A As shown, the indicator light 111 may be located on the power button 106. For example, the indicator light 111 may be controlled to display different colors to indicate the operation, sleep, power on, power off, wireless connection, charging, and other states of the device.
