Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection devices require manual adjustment or inefficient automatic methods for determining projection areas, leading to inconvenience and inaccuracies.
Innovation Solution
An electronic apparatus that uses sensor circuitry and processor to identify user gestures, calculate projection positions based on sensing data, and project images accordingly, incorporating features like microphone input for voice commands and multi-view functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment is used to change projection position, then projection position can be changed, but user convenience deteriorates
Solution Approach 1:
The patent replaces manual mechanical adjustment with gesture-based control. The sensor circuitry detects user gestures (hand movements) and the processor translates these gestures into projection position adjustments, eliminating the need for physical manipulation of the projector while achieving quick and intuitive position changes.
Solution Approach 2:
The patent introduces gesture recognition as an intermediary between user intent and projection position change. The sensor circuitry and processor act as mediators that interpret hand gestures and convert them into automated projection adjustments, providing a more convenient interface than direct manual adjustment.
2Ease of operation
If automatic search for projection area is used, then user operation is simplified, but processing time increases and accuracy deteriorates
Solution Approach 1:
The patent uses gesture-based preliminary indication to guide the automatic projection area search. Instead of completely automatic search, the user's gesture first indicates the desired projection area, and then the system automatically adjusts to that specific area, combining user guidance with automated adjustment for both speed and accuracy.
Solution Approach 2:
The system provides feedback by detecting the user's gesture and immediately adjusting the projection to match the indicated area. This closed-loop approach ensures the projection accurately reflects user intent while maintaining operational simplicity.
3Ease of operation
If automatic search for projection area is used, then user operation is simplified, but processing time increases
Solution Approach 1:
The user's gesture serves as preliminary action that pre-defines the target projection area before automatic adjustment begins. This eliminates the need for time-consuming full-area searches while maintaining automated operation simplicity.

AI summary
The electronic apparatus includes sensor circuitry to obtain sensing data; projection circuitry; and at least one processor configured to, based on a preset gesture of a user being identified based on the sensing data, identify a first position corresponding to a first part of the user and a second position corresponding to a second part of the user, the first position and the second position indicating the preset gesture, obtain direction information corresponding to the preset gesture based on the first position and the second position, obtain a projection position corresponding to the preset gesture based on a position of a projection surface and the direction information, and control the projection to project a projection image based on the projection position.
