Auxiliary terminal-control apparatus and method

An auxiliary terminal-control method, wherein the method is used to control a terminal device by using an auxiliary terminal-control apparatus, the auxiliary terminal-control apparatus comprises a back plate sticker, a control key embedded into the back plate sticker, a communications module, and a control module, and the method comprises:

• recognizing, by the control module, a target operation on the control key,
• and generating, based on the target operation, a corresponding target operation instruction, wherein the control key comprises a roll ball, operations on the roll ball comprise a roll operation and a press operation;
• and
• sending, by the communications module establishing a Bluetooth, Wi-Fi, GPRS, a USB, a serial port or an earphone jack communication connection, the target operation instruction to the terminal device, wherein the target operation instruction is used to operate an application program on the terminal device or trigger a service;
• wherein the generating, by the control module, based on the target operation, a corresponding target operation instruction comprises:
• determining, by the control module based on the target operation, the target operation instruction from configuration information, wherein the configuration information comprises a correspondence between an operation on the control key and a generated operation instruction
• wherein the configuration information comprises:
• generating a slide operation instruction for a touchscreen of the terminal device based on the roll operation on the roll ball, and
• generating a selection operation instruction based on the press operation on the roll ball, so as to select a location at which the slide operation currently stops;
• and
• wherein the back plate sticker has a curved surface, and has a recess on an outer surface in which the roll ball sits.

A non-transitory computer readable storage medium, comprising an instruction, wherein when the instruction runs on a computer, the computer is enabled to perform the steps:

• recognizing a target operation on a control key, and generating, based on the target operation, a corresponding target operation instruction, wherein the control key comprises a roll ball, operations on the roll ball comprise a roll operation and a press operation;
• and
• sending by establishing a Bluetooth, Wi-Fi, GPRS, a USB, a serial port or an earphone jack communication connection, the target operation instruction to the terminal device, wherein the target operation instruction is used to operate an application program on the terminal device or trigger a service;
• determining, based on the target operation, the target operation instruction from configuration information, wherein the configuration information comprises a correspondence between an operation on the control key and a generated operation instruction
• wherein the configuration information comprises:
• generating a slide operation instruction for a touchscreen of the terminal device based on the roll operation on the roll ball;
• and
• generating a selection operation instruction based on the press operation on the roll ball, so as to select a location at which the slide operation currently stops;
• and
• wherein the roll ball sits in a recess on an outer surface of a back plate sticker which has a curved surface.
