DETAILED DESCRIPTION

(13) The detailed description set forth below is intended as a description of various configurations of the subject technology and is not intended to represent the only configurations in which the subject technology may be practiced. The appended drawings are incorporated herein and constitute a part of the detailed description. The detailed description includes specific details for the purpose of providing a thorough understanding of the subject technology. However, it will be apparent to those skilled in the art that the subject technology may be practiced without these specific details. Like or similar components are labeled with identical element numbers for ease of understanding.

(14) In general, embodiments of the subject technology provide an improved lightweight computer mouse. As will be appreciated, aspects of the subject mouse reduce the weight of the mouse. This is particularly beneficial for electronic gaming (E-sports) applications. The improved subject mouse provides sufficient structural integrity yet enhances the performance of an e-athlete by reducing weight. The weight reduction increases the user's speed of mouse movement and minimizes the amount of strain placed on the user's hand. The result is improvement in user response time to events in the digital field of play and in some cases, improved performance over extended gaming sessions.

(15) Referring now to FIGS. 1-12, a computer mouse 100 (sometimes referred to in general as the “mouse 100”) is shown according to an exemplary embodiment. The mouse 100 generally includes a shell housing 110 that houses a control system 200 (which mostly hidden from view by the shell housing 110 but visible in FIGS. 10-12). The control system 200 may include a processor 230, a wheel input 240, and one or more button inputs 250. Some embodiments may include side buttons 270 which may be connected to the control system 200. The control system 200 may be connected to an output interface 180 which communicates the position of the mouse 100 and any user input actions (for example, button presses or wheel turns) to a computer (not shown). The embodiment in the Figures shows a wired computer mouse 100 (the output 180 represented by a partial view of a wire) but as will be understood, some embodiments may be a wireless computer mouse. In addition, the computer mouse 110 generally includes a position tracking input system 210 (shown in FIGS. 7, 8, 11, and 12) connected to the control system 200. The position tracking input system 210 may be an optical type system as shown or may be any other type system (for example, a roller ball).

(16) It will be appreciated that aspects of the shell housing 110 provide a lightweight computer mouse 100 that retains structural integrity while providing less strain on a user's hand during use. In an exemplary embodiment, the shell housing 110 includes a framework 115 of openings 150 in one or more surfaces (top, bottom, sides, and in some embodiments, in button sections). The shape of openings 150 may be defined by the arrangement of support members 155. The support members 155 may be rigid and connected to one another. In some embodiments, the support members 155 may connect to form angles defining a polygonal shaped opening 150, which may define the perimeter of an empty space between the support members 155. In an exemplary embodiment, the openings 150 may be a plurality of honeycomb cells. Accordingly, sometimes the openings 150 may be referred to as cells 150 depending on the embodiment. The polygonal cells 150 may include inner walls 165 formed the support members 155. The inner walls 165 may run axially into the shell housing 110. A radius of the openings 150 may be approximately 25 mm. The support members 155 may be approximately 10-20 mm thick.

(17) The shell housing 110 includes a top surface 120 (which may also be referred to as an upper shell surface or upper shell half). In some embodiments, the top surface 120 may be divided into a rear section 125 and a front section 130. The rear section 125 may be configured for resting a user's palm. The openings 150 may comprise between 10% to approximately 90% of the rear section's total surface area. As may be noted, some areas of the rear section 125 may not include an opening 150 which may be due to that part of the top surface 120 being used for an internal support structure (which may be visible for example in the cross-sectional view of FIG. 9). As will be appreciated, arranging the support members 155 to form openings in a substantial area of the top surface 120 creates a substantial reduction in the material used to produce the computer mouse 100, thus reducing a substantial amount of weight moved by the user over time. In some embodiments, the front section 130 may be split in half so that each half (or section if less than a half is used) may be its own button; a left button section 135 and a right button section 145. One or both button sections 135 and 145 may include the openings 150. In an exemplary embodiment, the openings 150 may be positioned toward a rear of each button section (135;145) leaving the front of each button solid providing a familiar tactile feel for the user and sufficient material to trigger an underlying button (see FIG. 10). Yet the position of the openings 150 still further reduce the weight profile of the computer mouse 100 by forming the openings 150 in areas of the button sections 135;145 that do not need material.

(18) The shell housing 110 may also include a bottom surface (or lower shell) 170 (see FIGS. 7-10). The bottom surface 170 may include an aperture to expose the position tracking input system 210 to an underlying surface as is known in the art. The bottom surface 170 may include the openings 150. In an exemplary embodiment, the support members 155 define openings 150 which may comprise between 10%-approximately 80% of to surface area of the bottom surface 170. The openings 150 may in some embodiments be positioned on at least two sides of the position tracking input system 210. In one embodiment, the openings 150 are positioned surrounding the position tracking input system 210. As will be appreciated, the footprint of solid housing material remaining after the inclusion of the support members 155 and openings 150 is minimal resulting in substantial weight reduction. Yet being a substantially planar surface, the bottom surface 170 remains unhampered in its integrity as most of the pressure applied by a user is shouldered by the solid perimeter edge of the bottom surface 170. As will be appreciated, a computer mouse 100 with openings 150 in the bottom surface substantially reduces the overall weight of the mouse in a section where one would not normally be motivated to include openings for anything other than a position tracking input device. The bottom surface of a computer mouse in general is designed to move in close proximity over an underlying surface and no other element is generally incorporated into the bottom other than an element tracking the underlying surface and thin casters for helping the bottom surface move along the underlying surface.

(19) In some embodiments, the shell housing 110 may include the support members 155 and openings 150 on a left side wall 140, a right side wall 160 or both. In some embodiments, one or both side walls 140; 160 may include a side trigger button(s) 270. The computer mouse 100 is shown for right-handed use with the trigger buttons 270 on the left side wall 140, however it will be understood that the buttons 270 may be positioned on the right side wall 160. In some embodiment, the openings 150 may be positioned over and up to the entirety of a side wall (140; 160) surface area (except for where other elements may be present such as the trigger buttons 270).

(20) It will be appreciated that the support members 155 for the framework 115 in such a manner that most of the normally solid areas of a computer mouse are replaced with geometric bridges between openings that provide a substantial reduction in weight yet provides a rigid feel for the user which may want to retain the familiar overall shape and feel of a mouse. Embodiments using hexagonally arranged support members 155 (which may include a depth element in a honeycomb shape) provide a substantially reliable support structure. The support members 155 and openings 150 may cover a substantial portion of the total shell housing 110 which may be for example, at least 25% of the total surface area and up to approximately 70% percent of the total surface area. The aggregate weight reduction provided by the support members 155 defining openings 150 significantly reduces the weight so much that a professional gamer will immediately feel the difference when operating the mouse 100.

(21) Those of skill in the art would appreciate that various components and blocks may be arranged differently (e.g., arranged in a different order, or partitioned in a different way) all without departing from the scope of the subject technology. For example, while the support members 155 are generally shown to form hexagons, other embodiments may modify the support member 155 connections to form other polygons such as triangles, squares, pentagons, or any number sided polygon higher or lower than a hexagon and any combination of shapes may be used. Some embodiments may use round or oval openings 150 providing similar weight reduction with a sufficient number of openings 150 integrated into the shell housing 110 or any of its surfaces. It will be understood that each shape formed by the support members 155 may have an advantage over another shape, and the choice of shape types included in the shell housing 110 may be a matter of design choice.

The previous description provides various examples of the subject technology, and the subject technology is not limited to these examples. Various modifications to these aspects will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other aspects.
