DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Fig. 1 is a front view of a handheld display device (hereinafter referred to as HHD) 10 according to an embodiment. Fig. 2 is a side view of the HHD 10. Fig. 3 is a perspective view of the HHD 10. In this application, the directions of up / down, front / back, and left / right refer to directions seen by the user based on a state in which the user positions the display unit 100 in front of the user's eyes and observes an image, and the directions are indicated in each drawing as necessary. The HHD 10 includes a display unit 100 and a handheld portion 200 .

[0010] The display unit 100 is an example of a display section according to the present invention, and is configured as a separate body from the handheld section 200 . An image display section (not shown in the figure) is provided on the rear surface (user side surface) of the display unit 100, which guides an enlarged virtual image of the display element to the user's eye by a display element and a display optical system. This allows the user to observe an image different from the real world in front of his or her eyes, and experience VR. The display element can be, but is not limited to, an EL panel, LCD, etc. In addition, a plurality of cameras 101 for capturing an image in front of the user's eyes are provided on the front of the display unit 100. An image in which CG (Computer Graphics) or the like is superimposed on a real image acquired by the camera 101 is generated and displayed on the image display unit, whereby the user can observe an image in which the real world is augmented with CG or the like, and can experience AR. The function of superimposing CG or the like on a real image may be realized by the display unit 100, or may be realized by external hardware connected to the display unit 100 via a cable 102. Although an example using the cable 102 has been described, the display unit 100 may be configured to be connected wirelessly to external hardware.

[0011] The hand-held portion 200 is provided with the display unit 100. The hand-held portion 200 also has a rod-shaped grip portion 202 for a user to grip, and as shown in Figures 2 and 3, the grip portion 202 is bent so as to be concave forward. More specifically, the hand-held portion 200 has a generally gate-like shape including left and right rod-shaped portions 203 and a beam portion 204 that spans between the upper ends of the left and right rod-shaped portions 203. A connecting portion 201 is provided at the lower portion of the beam portion 204, and the beam portion 204 supports the display unit 100 so as to suspend it via the connecting portion 201. The left and right rod-shaped portions 203 each form a grip portion 202, which is bent so as to be concave forward. Note that the hand-held portion 200 may be configured such that the rod-shaped portion 203 and the beam portion 204 are integrally molded, or may be configured from a plurality of parts.

[0012] Each part of the HHD10 is described in detail below. [Gripping part] 2, grip portion 202 bends around bending point P so as to be concave forward, in other words so as to be convex backward (toward the user). Bent portion 205 on the front surface of grip portion 202 is called portion A, an upper portion of portion A on the front surface is called portion B, and a lower portion of portion A on the front surface is called portion C. Bent portion 206 on the rear surface of grip portion 202 is called portion D, an upper portion of portion D on the rear surface is called portion E, and a lower portion of portion D on the rear surface is called portion F. Note that, although an example has been described in which grip portion 202 is bent so as to be concave forward, it may be curved so as to be concave forward.

[0013] Also, as shown in FIG. 1, when viewed from the front, the upper portion of the gripping portion 202 (parts B and E shown in FIG. 2) becomes wider toward the bottom, and the lower portion (parts C and F shown in FIG. 2) becomes narrower toward the bottom.

[0014] Moreover, the gripping portion 202 is not configured to limit the gripping position. A configuration that limits the gripping position is, for example, a configuration in which a grip is provided, or a portion is thicker than other portions, etc. The gripping portion 202 is a single rod that continues smoothly from the upper portion (portions B and E shown in FIG. 2) to the lower portion (portions C and F shown in FIG. 2), with no steps or portions with extremely different thicknesses, and is not configured to limit the gripping position.

[0015] The gripping portion 202 thus configured is bent to be concave forward and is not configured to limit the position at which it is gripped. This provides an affordance that reminds the user that it can be held in a variety of ways.

[0016] Here, examples of typical ways to hold the HHD10 will be described. FIG. 4 is a diagram for explaining the first holding method. In the first holding method, the second finger is hooked on part A of the gripping portion 202, the first finger is placed on part E, and the other three fingers are hooked on part C. The gripping portion 202 is bent, so that the user can imagine that the finger is hooked on part A. Furthermore, the gripping portion 202 is bent, so that the first finger can be placed on part E naturally without applying excessive force. This makes it easier to grip the gripping portion 202 tightly, so that the gripping stability of the HHD 10 can be improved. Furthermore, the pitch in the vertical direction at which the user touches the gripping portion 202 can be lengthened, so that the burden on the user's wrist can be reduced. All or part of parts A, C, and E may have flat surfaces in order to further improve the gripping stability.

[0017] FIG. 5 is a diagram for explaining the second holding method. In the second holding method, the second finger is placed on part B of the gripping portion 202, the first finger is placed on part F, and the other three fingers are hooked from part C to part F. This holding method makes it easier to hold the HHD 10 when in a forward-leaning observation posture, and the part touched by the four fingers excluding the second finger is the center of rotation, and the moment due to the weight of the HHD 10 is received by the second finger. When in a forward-leaning observation posture, the gripping portion 202 tries to rotate forward due to the moment due to the weight of the HHD 10, but the user tries to lengthen the pitch in the vertical direction touching the gripping portion 202 in order to reduce the strain on the wrist. At this time, the gripping portion 202 is bent, so that when the user stretches the second finger, it is easy to contact part B, and the second finger can be brought into contact with the gripping portion 202 that is trying to rotate forward without forcibly bending the second finger. This allows the user to lengthen the pitch in the vertical direction touching the gripping portion 202, thereby reducing the strain on the user's wrist. All or part of the portions B and F may have a flat surface in order to further improve gripping stability.

[0018] 6 is a diagram for explaining the third holding method. In the third holding method, all five fingers are hooked from part C to part F of the gripping part 202. With this holding method, the HHD 10 can be held without raising the hand as much as possible. Also, by bending the gripping part 202, the gripping part 202 is positioned near the position where the hand is naturally raised, which reduces the burden on the hand when used for a long period of time.

[0019] As described above with examples of ways of holding, by bending or curving the grip 202 so that it is concave forward, it is possible to remind the user that there are options for how to hold the HHD 10. This makes it easier for the user to notice that they can change to a different holding style, and they can change the holding style, so it is possible to provide a user-friendly HHD without forcing the user to hold it in the same way.

[0020] [Head contact part] 2, a head contact part 207 that bulges out backward (towards the user) is provided on the beam part 204 of the hand-held part 200. The user positions the display unit 100 in front of his / her eyes and brings the head contact part 207 into contact with the forehead, thereby stabilizing the HHD 10 so that it does not shift. The head contact part may be provided on the display unit 100.

[0021] [Connection structure between the handle and the display unit] 7 is a partial cross-sectional view of the top surface of the HHD 10. The connecting part 201 includes a rotating holder 208 having a rotating shaft 209. The rotating shaft 209 is an axis extending from left to right, i.e., an axis extending substantially parallel to a straight line connecting both eyes of the user, and this allows tilt adjustment of the hand-held part 200 and the display unit 100. By adjusting the tilt, the angle at which the grip part 202 protrudes forward relative to the display unit 100 can be adjusted. The rotating holder 208 holds the angle between the hand-held part 200 and the display unit 100 after the tilt adjustment. For example, a torque hinge can be applied as the rotating holder 208 in this manner, but is not limited thereto.

[0022] 8 is a diagram showing the state of tilt adjustment of the hand-held part 200 and the display unit 100 in the HHD 10, where (a) shows the default state and (b) shows the state after tilt adjustment so that the grip part 202 protrudes forward relative to the display unit 100. In this way, the angle at which the grip part 202 protrudes forward relative to the display unit 100 can be adjusted to a desired angle, improving usability. In addition, by adjusting the tilt of the hand-held part 200 and the display unit 100, the amount of convexity of the head contact part 207 with respect to the display unit 100 can be adjusted. This allows the user to use the HHD 10 by bringing the display unit 100 close to the eyes. Also, a user wearing glasses can use the HHD 10 by moving the display unit 100 away from the eyes so that the glasses do not come into contact with the display unit 100.

[0023] Although the configuration has been described in which the entire hand-held part 200 and the display unit 100 are tilt adjustable, for example, the hand-held part 200 may have a rotating holding part, and a part of the hand-held part 200 and the display unit 100 may be tilt adjustable. For example, the grip part 202 may be composed of multiple parts that rotate around a bending point P. In this case, the display unit 100 may be fixed to the beam part 204. Even with this configuration, the angle at which the lower part of the grip part 202 (parts C and F shown in FIG. 2) protrudes forward relative to the display unit 100 can be adjusted to a desired angle, improving usability.

[0024] [Display unit operation section] The end of the top surface of the display unit 100 has a shape that is one step lower than the center of the top surface, and this one step lower end is provided with an operation unit 103 such as a button. Note that the operation unit 103 is not limited to a button, and may be any member that allows the user to perform an operation, such as a dial or lever.

[0025] A space including the operation surface of operation unit 103 is secured so that the user can access operation unit 103 with his / her fingers. The grip unit 202 is configured so that the user can hold any part of the grip unit 202 without limiting the position or manner of holding it. Therefore, from the viewpoint of preventing erroneous operation by the user, it is preferable that the grip unit 202 is not provided with an operation unit. However, from the viewpoint of operability of the HHD 10, it is preferable that the hand-held unit 200 exposes the operation unit 103. Here, exposure does not mean that the hand-held unit 200 does not overlap with the operation unit 103 (the hand-held unit 200 does not cover the operation unit 103), but that a clearance is secured for the user to access the operation unit 103. In other words, as shown in FIG. 3, in the operation direction of the operation unit 103, the hand-held unit 200 overlaps with the operation unit 103 (the hand-held unit 200 is located above the operation unit 103). However, since a clearance is secured for the user to access the operation unit 103 with his / her fingers, it can be said that the hand-held unit 200 exposes the operation unit 103. The location of the operation unit 103 is not limited to the top surface of the display unit 100, but may be on the side surface or bottom surface.

[0026] [Cable guide] The gripping portion 202 is provided with a cable guide 210 that guides the cable 102 connected to the display unit 100. In this embodiment, the cable guide 210 is configured as a groove formed along the inner surface of the left gripping portion 202. By forming the cable guide 210 in a groove shape, the cable 102 can be arranged inside the inner surface of the gripping portion 202. This prevents the cable 102 from protruding from the inner surface of the gripping portion 202 and from interfering with the gripping action of the gripping portion 202. Note that the cable guide 210 is not limited to a groove, and may be configured to have a hook or a separate part attached to hold the cable 102.

[0027] Although the present invention has been described above with reference to the embodiments, the above embodiments are merely illustrative of the specific examples of the present invention, and the technical scope of the present invention should not be interpreted as being limited by these embodiments. In other words, the present invention can be embodied in various forms without departing from its technical concept or main features. In the above embodiment, the display unit 100 is supported so as to be suspended from the beams 204 of the hand-held portion 200, but the configuration in which the display is provided on the hand-held portion is not limited to this.
