Fingertip Overlay Rendering for Clearer Remote Video Instructions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication methods using video instructions are prone to misinterpretation due to difficulties in accurately conveying detailed instructions through oral descriptions or hand motions, particularly when indicating specific targets remotely.
Innovation Solution
An information processing apparatus that overlays a target video with a fingertip object, dynamically changing its representation based on user input, such as hand motions or additional inputs, to clearly indicate the intended target.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hand motion is used to indicate target in video instruction, then instruction delivery is enabled, but misinterpretation occurs due to inability to accurately convey details
Solution Approach 1:
The system creates a virtual copy of the instructor's hand and fingertip that is overlaid on the video. This virtual fingertip object replicates the hand motion to indicate the target, but provides enhanced precision through digital representation that can be clearly displayed and tracked, solving the problem of inaccurate target indication while maintaining ease of operation
Solution Approach 2:
The virtual fingertip object serves as an intermediary between the instructor's physical hand motion and the remote user's understanding. It translates the physical gesture into a clear visual indicator that can be precisely positioned and tracked on the video, eliminating misinterpretation while preserving the natural flow of instruction delivery
2Device complexity
If fixed representation of fingertip object is used, then system complexity is reduced, but adaptability to different instruction contexts is insufficient
Solution Approach 1:
The system dynamically adjusts the representation of the fingertip object based on the detection of hand motions and the context of the video instruction. The virtual object can change its visual characteristics (such as highlighting, tracking, or annotation styles) to adapt to different instruction scenarios, providing versatility without requiring excessive system complexity
Solution Approach 2:
The system changes parameters of the fingertip object representation (such as visual style, tracking behavior, or annotation features) based on the detected hand motion type and video context. This allows the same basic system to adapt to various instruction scenarios by adjusting display parameters rather than requiring multiple specialized systems

AI summary
An information processing apparatus includes a processor configured to: acquire a target video showing a target of an instruction, and fingertip information indicating a hand motion of a user; overlay the target video with a fingertip object indicated by the fingertip information; and present the fingertip object while changing a representation of the fingertip object based on input information included in the fingertip information or input by the user.
