VR Input Accessory Mount Layout for Unobstructed Camera Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The visibility of light emitting portions on an input device is crucial for accurate position tracking, but accessory components like straps can interfere with camera detection, reducing accuracy, and there is a need for easy attachment and detachment without disrupting the accessory's attached state.
Innovation Solution
The input device features an attaching portion on its inner surface for accessory components, with a fitting part having engagement protrusions that intersect the fitting direction, allowing for reduced interference and easy attachment/detachment, and the accessory component has a base covering these protrusions to secure a gap, facilitating smooth attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an accessory component (e.g., strap) is attached to the input device, then the device can be securely worn by the user, but the accessory component may interfere with camera detection of the tracked portion, reducing position tracking accuracy
Solution Approach 1:
The attaching portion is specifically positioned on the inner surface of the input device, which is the surface facing the user's hand or wrist during operation. This local placement ensures that the accessory component is attached in a region that does not obstruct the camera's line of sight to the tracked portion on the outer surface, thereby maintaining both secure attachment and accurate tracking
Solution Approach 2:
The solution moves the attachment function from the outer surface (where it would interfere with tracking) to the inner surface (where it does not interfere), utilizing the third dimension of the device structure. This spatial reconfiguration allows both the accessory attachment and camera tracking to coexist without interference
2Reliability
If the accessory component is firmly attached to the input device, then it remains securely in place during operation, but it becomes difficult to detach when needed
Solution Approach 1:
The fitting part incorporates engagement protrusions that can dynamically transition between engaged and disengaged states. During normal operation, the protrusions engage with the attaching opening to provide stable attachment. When detachment is needed, the protrusions can be easily disengaged by applying a small force, allowing quick removal without compromising security during use
Solution Approach 2:
The attachment mechanism is divided into separate engagement protrusions and corresponding receiving features in the attaching opening. This segmentation allows the attachment to be achieved through simple alignment and insertion, with each protrusion independently engaging its corresponding feature, making both attachment and detachment straightforward operations

AI summary
An input device (10) has a main body (11) including a grip (11B) and an operating section (11A) in which an input button (13) and the like are disposed, an outer surface (31a, 31b) provided with a tracked portion (H) to be tracked by an external camera, an inner surface (31c, 31e) that faces a hand or wrist of a user while the user is holding the grip (11B), and an attaching opening (33) that is provided on the inner surface (31c, 31e) and to which an accessory component (60) is to be attached. With this arrangement, the influence of the accessory component (60) on the detection of the tracked portion (H) by the camera can be reduced when the accessory component (60) is attached to the attaching opening (33) of the input device (10).
