In order to explain the technical content, structural features, objectives and effects of the present invention in detail, the following detailed description is given by way of example.

The presenting device of the optical finger navigation sensor (OFN) is one or a plurality of light-emitting elements 2 disposed around the optical pointing sensor 1. The light-emitting state of the light-emitting element 2 is controlled by the electronic device using the optical pointing sensor 1. In general, electronic devices such as handheld network mobile devices that use optical pointing sensor 1 employ graphical interfaces that provide indicators in the graphical interface for the user to select. The user can move the finger on the optical pointing sensor 1 to complete the movement of the indicator in the graphic interface. When the indicator in the graphical interface stays at a specific location, such as a system button (such as confirmation or cancellation), a network connection, and an instruction confirmation in the system, the light-emitting component 2 receives an instruction inside the electronic device and starts continuous or intermittent. Illuminating, thereby providing the user with a prompt to click and continuously click on the optical pointing sensor 1.

The above light-emitting element 2 preferably uses a blue or green light source. Of course, it is also possible to use other colors of light such as red or yellow depending on the actual needs of the user. These light-emitting elements 2 obtain power supply from the inside of the electronic device using the optical pointing sensor 1, and accept an indication of the operating state of the electronic device. The circuit implementation is well-suited to those skilled in the art and will not be specifically described herein.

Figures 1 through 4 show different embodiments of the presenting device of the optical pointing sensor, respectively. In the first embodiment, the light-emitting element 2 is annular and surrounds the circumference of the circular optical pointing sensor 1; in the second embodiment, two of the light-emitting elements 2 are respectively disposed in a circular optical orientation. The left and right sides of the sensor 1 (preferably 5 mm distance); in the third embodiment, the light-emitting element 2 is frame-shaped, surrounding the square optical pointing sensor 1; in the fourth embodiment, the light-emitting element There are two, two, respectively disposed on the left and right sides of the square optical pointing sensor 1 (preferably 5 mm distance). There are many similar variants, which are not listed here.

The prompting device of the present invention is constructed on the optical pointing sensor 1 and utilizes the position of the loopback and the position in the system to perform the action after the processing of the operating system. The light-emitting component 2 provides blue and green optical indications, prompting the general user to proceed to the next step. The action, or when the operating system performs the related prompt action, provides a prompt for the next action that the user can perform.

As shown in FIG. 5, the prompting method of the prompting device of the optical pointing sensor is as follows. The flow begins in step S10, in which the operating system issues a command signal based on the task being executed. For example, during the process of installing the program, the user needs to confirm the installation process. If the system button is selected to confirm or cancel, the operating system will send a command signal.

Step S20: The operating system determines whether the command signal needs to be prompted. If the prompt is needed, step S30 is performed. Step S30: According to the command signal, the prompting device of the optical pointing sensor sends a corresponding prompt light. According to the above command signal, it is necessary to prompt the user for the operation. The illuminating element 2 emits corresponding prompt light, such as continuous green light, to prompt the user to confirm. After step S30 is completed, the process proceeds to step S40; in step S40, it is determined whether the user performs an action; if the user is sensed to perform the action within the set time, step S50 is performed; in step S50, the optical pointing sensor is performed. The reward informs the location and performs the action, and returns information to the operating system. For example, during the set time, the optical pointing sensor 1 senses that the user has performed a click action, and then reports the click position and returns information to the operating system, and the operating system knows that the installation or cancellation process is continued.

In step S20, the operating system determines whether the command signal needs to be prompted. If the prompt is not required, step S25 is performed; and step S25: the prompting device of the optical pointing sensor 1 does not prompt.

In step S40, it is determined whether the user performs an action; if the user does not sense that the action is performed within the set time, step S45 is performed; step S45: the report informs the user of the operating system that the action is not performed. For example, if the user does not perform the confirmation action within the set time, the user is notified that the operation system user has not confirmed.

In addition, when an electronic device such as a palm-type network mobile device has a system status prompt or receives external information (such as a short message or a push information), the electronic pointing device may also be prompted by the prompting device of the optical pointing sensor.

While the invention has been described above in terms of the preferred embodiments, the invention is not intended to limit the scope of the invention, and the invention may be practiced otherwise without departing from the spirit and scope of the invention. Retouching. Therefore, the scope of the invention is defined by the scope of the appended claims.
