Description

Technical Field

[0001] The present invention belongs to the technical field of human-computer interaction, and relates to a processing device and method, and in particular to a signal processing device and method. Background Art

[0002] Human-computer interaction (HCI or HMI) is a discipline that studies the interactive relationship between systems and users. Systems can be various machines or computerized systems and software. The human-computer interaction interface usually refers to the part visible to the user. Users communicate with and operate the system through the human-computer interaction interface. This can be as small as the play button on a radio or as large as the dashboard on an airplane or the control room of a power plant. The design of the human-computer interaction interface must include the user's understanding of the system (i.e., mental model), which is for the sake of system usability or user-friendliness.

[0003] At present, encoders are widely used in the field of human-computer interaction, but the structure of multi-axis encoders is relatively complex, and the cost and size are relatively large.

[0004] Therefore, how to provide a signal processing device and method to solve the defects of the existing technology using a complex multi-axis encoder, which leads to large cost and volume, has become a technical problem that needs to be urgently solved by those skilled in the art. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a signal processing device and method for solving the problem that the prior art uses a multi-axis encoder with a complex structure, resulting in large cost and volume.

[0006] To achieve the above-mentioned purpose and other related purposes, the present invention provides a signal processing device, including: an action receiving device for receiving a manipulation action occurring thereon; an encoder for converting the manipulation action received by the action receiving device arranged thereon into a manipulation signal; an identifier connected to the encoder for identifying the manipulation signal and outputting an axis signal corresponding thereto.

[0007] In one embodiment of the present invention, the encoder includes a dual-axis encoder or a single-axis encoder.

[0008] In one embodiment of the present invention, when the encoder is a dual-axis encoder, the action receiving device is a mechanical cap nested on the dual-axis encoder; when the encoder is a single-axis encoder, the action receiving device is a button-type cap set on the single-axis encoder.

[0009] In one embodiment of the present invention, the surface layer of the mechanical cap includes a front operating layer and a side operating layer.

[0010] In one embodiment of the present invention, when the encoder is a dual-axis encoder, the manipulation action includes a rotation action of operating the front operation layer or a rotation action of operating the side operation layer; when the encoder is a single-axis encoder, the manipulation action includes a pressing action of operating the button.

[0011] In one embodiment of the present invention, the interior of the mechanical cap is made of a conductive material; the front operating layer is an insulating layer; and the side operating layer is a conductive layer.

[0012] In one embodiment of the present invention, the side operating layer is electrically connected to the identifier through the conductive structure and the conductive metal sheet inside the encoder to provide a control signal to the identifier.

[0013] In one embodiment of the present invention, when the encoder is a dual-axis encoder, the dual-axis encoder reads the angular displacement corresponding to the rotational action of the front operating layer, and prevents the angular displacement from being converted into a control signal through the front operating layer. When the identifier does not receive the control signal, it identifies it as a first axis signal; the first axis signal is associated with the failure to receive the control signal; or the dual-axis encoder reads the rotational action of the side operating layer, converts the angular displacement corresponding to the rotational action into a control signal, and outputs the control signal to the identifier through the side operating layer. When the identifier receives the control signal, it identifies it as a second axis signal; the second axis signal is associated with the reception of the control signal.

[0014] In one embodiment of the present invention, when the encoder is a single-axis encoder, when the single-axis encoder does not read the pressing action of the button and the identifier does not receive the control signal, it identifies it as a first-axis signal; the first-axis signal is associated with the failure to receive the control signal; or the single-axis encoder reads the pressing action of the button and generates the control signal, and when the identifier receives the control signal, it identifies it as a second-axis signal; the second-axis signal is associated with the reception of the control signal.

[0015] Another aspect of the present invention provides a signal processing method, comprising: receiving a manipulation action occurring thereon; converting the manipulation action into a manipulation signal; identifying the manipulation signal, and outputting an axis signal corresponding thereto.

[0016] As described above, the signal processing device and method of the present invention have the following beneficial effects:

[0017] The signal processing device and method of the present invention can realize the function of a multi-axis encoder without adopting a new mechanical mechanism, and both cost and volume can be reduced, bringing more space and convenience to the design of human-computer interaction.

[0035] Example 1

[0036] This embodiment provides a signal processing device, including:

[0037] An action receiving device, for receiving a manipulation action occurring thereon;

[0038] An encoder, configured to convert a manipulation action received by a motion receiving device disposed thereon into a manipulation signal;

[0039] The identifier is connected to the encoder and is used to identify the control signal and output an axis signal corresponding to the control signal.

[0040] The signal processing device provided by this embodiment will be described in detail below with reference to the figures. Figure 1 , which is a schematic diagram showing the principle structure of a signal processing device in one embodiment. Figure 1 As shown, the signal processing device 1 includes a motion receiving device 11 , an encoder 12 and a recognizer 13 .

[0041] In this embodiment, the encoder 12 includes a dual-axis encoder or a single-axis encoder. The identifier 13 is a PCB circuit board with an identification function.

[0042] See also Figure 2 , which is a schematic diagram of an implementation structure of a signal processing device. Figure 2 As shown, when the encoder 12 is a dual-axis encoder, the motion receiving device 11 is a mechanical cap embedded in the dual-axis encoder. The interior of the mechanical cap is made of conductive material.

[0043] In this embodiment, the surface layer of the mechanical cap includes a front operating layer 111 and a side operating layer 112. The front operating layer 111 is an insulating layer and is not electrically conductive to the identifier 13. The side operating layer 112 is a conductive layer that is electrically conductive to the identifier 13 through the conductive structure within the encoder 12 and the conductive metal sheet 113, thereby providing control signals to the identifier 13. In this embodiment, a nut 114 is provided between the mechanical cap and the dual-axis encoder to secure the mechanical cap to the dual-axis encoder.

[0044] One end of the conductive metal sheet 113 symmetrically arranged on both sides of the dual-axis encoder is clamped between the nut 114 and the encoder, and the other end of the conductive metal sheet 113 is fixed to the PCB circuit board through the nut 115.

[0045] In this embodiment, when the encoder is a dual-axis encoder, the manipulation action includes a rotation action of operating the front operating layer or a rotation action of operating the side operating layer.

[0046] When the encoder 12 is a dual-axis encoder, the dual-axis encoder reads the angular displacement corresponding to the rotational movement of the front operating layer 111, and prevents the angular displacement from being converted into a control signal through the front operating layer. When the identifier does not receive the control signal, it identifies it as a first-axis signal (in this embodiment, the first-axis signal is an X-axis signal); wherein, the first-axis signal is associated with the failure to receive the control signal.

[0047] Or the dual-axis encoder reads the rotational action of the side operating layer 112, converts the angular displacement corresponding to the rotational action into a control signal, and outputs the control signal to the identifier through the side operating layer. When the identifier receives the control signal, it identifies it as a second-axis signal (in this embodiment, the first-axis signal is the Y-axis signal); wherein, the second-axis signal is associated with the received control signal.

[0048] See also Figure 3 , which is another schematic diagram of the structure of the signal processing device. Figure 3 As shown, when the encoder 12 is a single-axis encoder, the action receiving device 11 is a button-type cap 116 provided on the single-axis encoder.

[0049] When the encoder is a single-axis encoder, the manipulation action includes a pressing action of the button. When the single-axis encoder does not read the pressing action of the button and the identifier 13 does not receive the manipulation signal, it is identified as a first axis signal (in this embodiment, the first axis signal is the X-axis signal); the first axis signal is associated with the failure to receive the manipulation signal. Alternatively, the single-axis encoder reads the pressing action of the button and generates the manipulation signal. When the identifier receives the manipulation signal, it is identified as a second axis signal (in this embodiment, the first axis signal is the Y-axis signal); the second axis signal is associated with the receipt of the manipulation signal.

[0050] The signal processing device described in this embodiment can realize the function of a multi-axis encoder without adopting a new mechanical mechanism, which can reduce the cost and volume, and bring more space and convenience to the design of human-computer interaction.

[0051] Example 2

[0052] This embodiment provides a signal processing method, which is applied to the signal processing device provided in Example 1. The signal device includes an action receiving device, an encoder and an identifier. The encoder includes a dual-axis encoder or a single-axis encoder. When the encoder is a dual-axis encoder, the action receiving device is a mechanical cap nested on the dual-axis encoder; when the encoder is a single-axis encoder, the action receiving device is a button-type cap provided on the single-axis encoder. The surface layer of the mechanical cap includes a front operating layer and a side operating layer. The interior of the mechanical cap is made of conductive material; the front operating layer is an insulating layer; and the side operating layer is a conductive layer. The side operating layer is connected to the identifier through the conductive structure and the conductive metal sheet inside the encoder to provide the control signal to the identifier.

[0053] See also Figure 4 , which is a flow chart of a signal processing method in one embodiment. Figure 4 As shown, the signal processing method specifically includes the following steps:

[0054] S41: Receive a manipulation action occurring on the encoder. When the encoder is a dual-axis encoder, the manipulation action includes rotating the front operating layer or rotating the side operating layer. When the encoder is a single-axis encoder, the manipulation action includes pressing the button.

[0055] S42, converting the manipulation action into a manipulation signal.

[0056] S43, identifying the control signal and outputting an axis signal corresponding thereto.

[0057] Specifically, when the encoder is a dual-axis encoder, the dual-axis encoder reads the angular displacement corresponding to the rotational action of the front operating layer, and prevents the angular displacement from being converted into a control signal through the front operating layer. When the identifier does not receive the control signal, it identifies it as a first-axis signal (in this embodiment, the first-axis signal is an X-axis signal); wherein, the first-axis signal is associated with the failure to receive the control signal.

[0058] Or the dual-axis encoder reads the rotational action of the side operating layer, converts the angular displacement corresponding to the rotational action into a control signal, and outputs the control signal to the identifier through the side operating layer. When the identifier receives the control signal, it identifies it as a second axis signal (in this embodiment, the first axis signal is the Y-axis signal); wherein, the second axis signal is associated with the received control signal.

[0059] When the encoder is a single-axis encoder, the manipulation action includes a pressing action of the button. When the single-axis encoder does not read the button pressing action and the identifier does not receive the manipulation signal, it identifies it as a first-axis signal (in this embodiment, the first-axis signal is the X-axis signal); the first-axis signal is associated with the failure to receive the manipulation signal. Alternatively, the single-axis encoder reads the button pressing action and generates the manipulation signal. When the identifier receives the manipulation signal, it identifies it as a second-axis signal (in this embodiment, the first-axis signal is the Y-axis signal); the second-axis signal is associated with the receipt of the manipulation signal.

[0060] In summary, the signal processing device and method described herein can achieve the functionality of a multi-axis encoder without requiring a new mechanical mechanism, reducing both cost and size, and providing more space and convenience for human-computer interaction designs. This invention effectively overcomes the shortcomings of existing technologies and possesses high industrial value.
