[0003] Although many types of mice exist, they still require palm-based operation, meaning existing mice do not relieve the user's hands during control. The inventor believes this disadvantage can be overcome and therefore proposes a suitably designed electronic operating system that effectively mitigates this drawback.

[0004] The embodiments of the present invention provide an electronic working system, a wrist mouse and a wrist mouse sensor body with which the deficiencies that can occur in existing mice can be effectively improved.

[0005] The embodiments of the present invention disclose an electronic working system comprising a wrist mouse, a processing device, and a display. The wrist mouse comprises a sensor body and a wrist strap. The sensor body comprises a housing having an outer wrist section and an ulna section adjoining the outer wrist section, wherein a wearing angle of between 80 degrees and 100 degrees is formed between the outer wrist section and the ulna section, a myoelectric sensor mounted inside the housing and oriented towards the inside of the housing, and a motion sensor installed inside the ulna section and directed outwards from the housing.The wrist strap is detachably attached to the outer wrist section and the ulna section of the housing, allowing the wrist mouse to be worn on a user's wrist with the outer wrist section and wrist strap in place, such that the ulna section and the motion sensor are adjacent to the ulna of the wrist. When the wrist mouse is worn on the wrist, the myoelectric sensor can detect changes in the user's gestures while the ulna section rests flexibly against a work surface, and the motion sensor tracks the movement of the ulna section. The processing device is wirelessly connected to the myoelectric sensor and the motion sensor of the wrist mouse.The display is electrically coupled to the processing device, whereby, when the wrist mouse is worn on the wrist, the myoelectric sensor and the motion sensor can control a mouse pointer displayed on the display via the processing device.

[0006] The embodiments of the present invention also disclose a wrist mouse comprising a sensor body and a wrist strap. The sensor body comprises a housing having an outer wrist section and an ulna section adjoining the outer wrist section, wherein a wearing angle of between 80 degrees and 100 degrees is formed between the outer wrist section and the ulna section, a myoelectric sensor mounted inside the housing and oriented towards the inside of the housing, and a motion sensor installed inside the ulna section and directed outwards from the housing.The wrist strap is detachably attached to the outer wrist section and the ulna section of the housing, allowing the wrist mouse to be worn on a user's wrist with the outer wrist section and wrist strap positioned so that the ulna section and the motion sensor are adjacent to the ulna of the wrist. When the wrist mouse is worn on the wrist, the myoelectric sensor can detect changes in the user's gestures while the ulna section rests against a work surface, with the motion sensor capturing the movement of the ulna section.

[0007] The embodiments of the present invention further disclose a sensing body of a wrist mouse, comprising a housing having an outer wrist section and an ulna section adjoining the outer wrist section, wherein a wearing angle between 80 degrees and 100 degrees is formed between the outer wrist section and the ulna section, a myoelectric sensor which is mounted inside the housing and oriented towards the inside of the housing and serves to detect a change in a user's gesture, and a motion sensor which is installed inside the ulna section and directed outwards from the housing, wherein when the ulna section is movably in contact with a work surface, a movement path of the ulna section can be detected by means of the motion sensor.

[0008] In summary, it can be said that in the electronic working system according to the invention, the wrist mouse and the sensor body of the wrist mouse, which are disclosed in the exemplary embodiments of the present invention, a carrying angle is formed by the housing to facilitate wearing on the user's wrist, which allows the user to control the wrist mouse through the wrist and thus relieve both hands.

[0009] Furthermore, the electronic work system, the wrist mouse and the wrist mouse sensor, which are disclosed in the embodiments of the present invention, are equipped not only with the myoelectric sensor, but also with the motion sensor in the ulna section for contact with the work surface, so that the wrist mouse (or the sensor) can be operated by the user's gesture changes and the movement path of the ulna section.

[0011] The following describes, with reference to specific embodiments, the embodiments of an electronic work system, a wrist mouse, and a wrist mouse sensor, which are disclosed within the scope of the present invention. Those skilled in the art will recognize that the advantages and technical effects of the present invention can be derived from the disclosures in this description. The present invention can be implemented or applied through other specific embodiments, whereby various modifications or alterations can be made to the details disclosed in this description, depending on requirements and application, without departing from the fundamental ideas of the present invention. Furthermore, it should be noted that the individual components of the present invention are not shown in their actual size, but only schematically.The following embodiments serve to further describe the configurations of the present invention, but the corresponding disclosures do not constitute a limitation of the scope of protection of the present invention.

[0012] It is understood that the terms "first," "second," "third," etc., used to describe various elements or features, are not to be interpreted as restrictive. Rather, such terms serve to distinguish one element from another or one feature from another. Furthermore, the term "or" used in this description may, where applicable, encompass any of the listed items or a combination of several such items. [First embodiment]

[0013] It will be directed to the Fig. Reference is made to figures 1 to 6, which represent a first embodiment of the present invention. As in Fig. As shown in Figures 1 to 3, the present embodiment discloses an electronic work system 1000 comprising a wrist mouse 100, a processing device 200 wirelessly connected to the wrist mouse 100, and a display 300 electrically coupled to the processing device 200. The wrist mouse 100 can interact with the processing device 200 to control a mouse pointer 301 displayed on the display 300.

[0014] It should be noted that in the present embodiment, the electronic work system 1000 is illustrated by the interaction of the wrist mouse 100 with the processing device 200 and the display 300, but the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the wrist mouse 100 can also be used (e.g., sold) alone or in combination with other components, depending on the actual needs. The structure of the wrist mouse 100 will be explained below, followed by a description of the connection between the wrist mouse 100 and the processing device 200 or the display 300.

[0015] In the present embodiment, the wrist mouse 100 is designed to be worn on the user's wrist. That is to say, any mouse that is not worn on the wrist differs from the wrist mouse 100 described in this embodiment. Furthermore, the wrist mouse 100 comprises a sensor body 1 and a wrist strap 2, which is detachably attached to the sensor body 1. However, the present invention is not limited to this. For example, in other embodiments of the present invention not shown, the sensor body 1 can also be used (e.g., sold) alone or in combination with other components, depending on the actual needs.

[0016] As in Fig. As shown in Figures 3 to 5, the detection body 1 comprises a housing 11 and a sensor module 12 mounted in the housing 11. Depending on requirements, the detection body 1 can also be equipped with further electronic components in the housing 11, which is not limited within the scope of the present invention. The housing 11 is essentially L-shaped and has an outer wrist section 111 and an ulna section 112 adjoining the outer wrist section 111, wherein a wearing angle σ11 between 80 degrees and 100 degrees is formed between the outer wrist section 111 and the ulna section 112.

[0017] Furthermore, the wrist strap 2 is detachably attached to the outer wrist section 111 and the ulna section 112 of the housing 11. The sensor body 1 interacts with the wrist strap 2 through the configuration of the wearing angle σ11 such that the wrist mouse 100 can be worn on the user's wrist with the outer wrist section 111 and the wrist strap 2 in place. That is, the configuration of the wearing angle σ11 ensures that when the wrist mouse 100 is worn on the wrist, the ulna section 112 is adjacent to (or in contact with) the ulna of the wrist, while the outer wrist section 111 is adjacent to (or in contact with) the outer surface of the wrist.

[0018] It should be added that the installation between the sensor body 1 and the wrist strap 2 can be adapted and varied according to actual needs. However, to facilitate understanding of the present embodiment, the installation between the sensor body 1 and the wrist strap 2 is described below from one perspective, but the present invention is not limited to this.

[0019] The outer wrist section 111 has a mounting groove 1111 located away from the ulna section 112, while at least one positioning rib 1121 is formed on the inner side of the ulna section 112. The wrist strap 2 has the shape of an elongated arc and has a first end section 21, a second end section 22 located opposite the first end section 21, and several adjustment holes 23 arranged from the second end section 22 towards the first end section 21.

[0020] The first end section 21 is detachably mounted in the mounting groove 1111 of the outer wrist section 111 and at least one of the several adjustment holes 23 is detachably attached to the at least one positioning rib 1121 of the ulna section 112, so that the wrist mouse 100 can be adjusted to the user's wrist.

[0021] More precisely, in the present embodiment, the at least one positioning rib 1121 is provided in a number of two, with two of the multiple adjustment holes 23 being detachably attached to the two positioning ribs 1121, but the present invention is not limited thereto. Furthermore, one of the positioning ribs 1121 is located near the outer wrist section 111 and is inclined relative to the other positioning rib 1121 such that the extension directions of the two positioning ribs 1121 enclose a positioning angle σ1121 of no more than 45 degrees, thereby achieving a more secure connection between the ulna section 112 and the wrist ligament 2.

[0022] Since, after the first wearing of the wrist mouse 100 on the user's wrist, the wrist strap 2 is already engaged according to the size of the wrist by at least one suitable adjustment hole 23 with at least one positioning rib 1121 of the ulna section 112, the next wearing of the wrist mouse 100 can be carried out by inserting and removing the first end section 21 of the wrist strap 2 into or out of the mounting groove 1111 of the outer wrist section 111 (see e.g. Fig. 6), so that the user can quickly carry the wrist mouse 100.

[0023] Furthermore, in other embodiments of the present invention not shown, the wrist mouse 100 can also be equipped with functional components (e.g. a clockwork mechanism) in the outer wrist section 111 according to actual needs in order to increase the added value of the wrist mouse 100.

[0024] In the present embodiment, the sensor module 12 comprises a myoelectric sensor 121 (EMG sensor), a motion sensor 122, and an inertial sensor 123, but the present invention is not limited thereto. In other embodiments of the present invention not shown, for example, the inertial sensor 123 can be omitted or replaced by other components, depending on practical requirements.

[0025] Furthermore, the myoelectric sensor 121 is mounted inside the housing 11 and oriented towards the inside of the housing 11. That is, in the present embodiment, the myoelectric sensor 121 is attached to the outer wrist section 111 to facilitate the detection of wrist movement, but is not limited to this. Thus, when the wrist mouse 100 is worn on the wrist, the myoelectric sensor 121 can detect a change in the user's gesture.

[0026] Furthermore, the inertial sensor 123 is mounted within the housing 11 and can interact with the myoelectric sensor 121 to jointly detect changes in the user's gestures. The inertial sensor 123 can comprise a multi-axis gyroscope and a multidirectional accelerometer and / or a magnetometer. However, the specific configuration of the inertial sensor 123 can be adapted and varied according to actual needs, which is not limited within the scope of the present invention.

[0027] The motion sensor 122 is installed within the elliptical section 112 and faces outwards from the housing 11. That is, as in Fig. As shown in Figures 1 to 4, when the wrist mouse 100 is worn on the wrist, the ulna section 112 and the motion sensor 122 are located near the ulna of the wrist and the ulna section 112 rests movably against a work surface P, whereby a movement path of the ulna section 112 (or the wrist mouse 100) is detected by means of the motion sensor 122.

[0028] The myoelectric sensor 121, the motion sensor 122 and the inertial sensor 123 of the wrist mouse 100 are wirelessly connected to the processing device 200, so that the myoelectric sensor 121, the motion sensor 122 and the inertial sensor 123 can control the mouse pointer 301 displayed on the display 300 via the processing device 200.

[0029] In this way, the wrist mouse 100 in the present embodiment can be worn on the user's wrist by means of the detection body 1, which is configured such that the housing 11 forms the carrying angle σ11, so that the user can control the wrist mouse 100 via the wrist, thereby relieving his hands.

[0030] Furthermore, the wrist mouse 100 is equipped not only with the myoelectric sensor 121, but also with the motion sensor 122 in the ulna section 112 for placement on the work surface P, so that the wrist mouse 100 (or the sensor body 1) can be operated by the user's gesture changes and the movement path of the ulna section 112 (e.g. to control the mouse pointer 301).

[0031] It should be added that in the present embodiment, the processing device 200 is a main unit of a notebook computer and the display 300 is a screen of the notebook computer, but the present invention is not limited thereto. Thus, in other embodiments of the present invention not shown, the processing device 200 may, for example, also be a desktop computer, wherein the display 300 is a screen or a projection mechanism that is electrically coupled to the desktop computer.

[0032] As in Fig. As shown in Figures 1 to 4, the wrist mouse 100, when worn on the wrist, can be in a mouse-controlled state by having the ulna section 112 rest against the working surface P (as shown in Figure 1 to 4). Fig. 1 shown), or in a gesture-controlled state, by which the ulna section 112 leaves the work surface P (as in Fig. 2 shown).

[0033] When the Wrist Mouse 100 is worn on the wrist and is in mouse-controlled mode (as in Fig. 1 and Fig. (as shown in Figure 4), the gesture change detected by the myoelectric sensor 121 and the movement path detected by the motion sensor 122 can be used via the processing device 200 to control the mouse pointer 301 displayed on the display 300.

[0034] When the Wrist Mouse 100 is worn on the wrist and is in gesture-controlled mode (as in Fig. 2 and Fig. (as shown in Figure 4), the gesture change detected by the myoelectric sensor 121 can be used via the processing device 200 to control the mouse pointer 301 displayed on the display 300, while the motion sensor 122 is not used to control the mouse pointer 301. [Second embodiment]

[0035] It will be directed to the Fig.Reference is made to Figures 7 to 10, which represent a second embodiment of the present invention. Since the present embodiment is similar to the first embodiment described above, the similarities between the two embodiments are not repeated. The differences between the present embodiment and the first embodiment described above are outlined below:

[0036] In the present embodiment, the detection body 1 comprises several shortcut buttons 13 attached to the ulna section 112, located on two opposite sides of the motion sensor 122. Each of the shortcut buttons 13 can be assigned the function of the left or right button of a general mouse or any shortcut key function of a keyboard according to actual needs in order to effectively improve the comfort of the wrist mouse 100, which is not subject to any limitation within the scope of the present invention.

[0037] Furthermore, the structural fit between the multiple shortcut keys 13 and the ulna section 112 can be adapted and varied according to actual needs. However, to facilitate understanding of the present embodiment, the structural fit between the multiple shortcut keys 13 and the ulna section 112 is described below from one perspective, but the present invention is not limited to this.

[0038] The ulna section 112 has a contact surface 1122 for resting against the work surface P and several chamfered surfaces 1123 adjoining the contact surface 1122 on two opposite sides. In the present embodiment, the motion sensor 122 is directed outwards from the ulna section 112 through the contact surface 1122. The several chamfered surfaces 1123 are arranged essentially symmetrically with respect to the contact surface 1122, with each chamfered surface 1123 enclosing a trigger angle σ1123 with an extension of the contact surface 1122, which facilitates wrist rotation (i.e., the trigger angle σ1123 is not greater than 30 degrees).

[0039] Furthermore, each of the shortcut keys 13 is arranged on one of the beveled surfaces 1123, with one of the shortcut keys 13 being located near the outer wrist section 111, while another of the shortcut keys 13 is located away from the outer wrist section 111. Each of the shortcut keys 13 is located in a space enclosed by the associated beveled surface 1123 and the extension of the support surface 1122 to prevent accidental contact with one of the shortcut keys 13.

[0040] According to the above, when worn on the wrist and in mouse-controlled mode, the wrist mouse 100 can selectively rotate to one side of the motion sensor 122 to press the corresponding quick key 13 (i.e., the wrist mouse 100 can selectively rotate towards one of the beveled surfaces 1123 by an angle not greater than the trigger angle σ1123 to press the associated quick key 13).

[0041] It should also be noted that both the quick-access buttons 13 of the sensing body 1 and the corresponding structures (e.g., the chamfered surfaces 1123) are provided in a quantity of two in the present embodiment, but the present invention is not limited thereto. In other embodiments of the present invention not shown, the number of quick-access buttons 13 arranged on the sensing body 1 and the number of chamfered surfaces 1123 can each be at least one. In this case, the at least one quick-access button 13 is arranged on the at least one chamfered surface 1123 near the motion sensor 122 and is located in a space enclosed by the at least one chamfered surface 1123 and the extension of the support surface 1122.Furthermore, when worn on the wrist and in mouse-controlled mode, the wrist mouse 100 can rotate towards the at least one beveled surface 1123 to press the at least one quick key 13. [Technical effects of the embodiments of the present invention]

[0042] In summary, the electronic work system, wrist mouse and wrist mouse sensor body disclosed in the embodiments of the present invention form a carrying angle through the housing to facilitate carrying on the user's wrist, thus enabling the user to control the wrist mouse through the wrist and thereby relieving both hands.

[0043] Furthermore, the electronic work system, the wrist mouse and the wrist mouse sensor, which are disclosed in the embodiments of the present invention, are equipped not only with the myoelectric sensor, but also with the motion sensor in the ulna section for contact with the work surface, so that the wrist mouse (or the sensor) can be operated by the user's gesture changes and the movement path of the ulna section.
