Solution Overview
Problem
There is a need for a hand-held pointing device that can seamlessly operate both smart TVs and computers, as existing devices often fail to provide a unified input solution for these platforms.
Innovation Solution
A hand-held pointing device equipped with a main body, a first image sensing device, a light emitting device, a second image sensing device, and a processing circuit, which determines whether it is operating on a smart TV or computer by sensing images through transparent areas and emitting a light source, allowing it to switch between remote controller and mouse modes based on detected references.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hand-held device is designed to support both smart TV and computer operations, then the adaptability and versatility are improved, but the device complexity increases due to the need for multiple sensing devices and processing circuits
Solution Approach 1:
The hand-held pointing device is designed to perform multiple functions by supporting both remote controller mode for smart TV operation and mouse mode for computer operation. The device uses a processing circuit that can identify different operating environments through image sensing and automatically switch between modes, making a single device universal for both platforms
Solution Approach 2:
The device dynamically adapts its operating mode based on the detected environment. The processing circuit continuously analyzes images from the image sensing device and switches between remote controller mode and mouse mode depending on whether a reference light source (smart TV) or operating surface (computer) is detected, making the device behavior flexible and context-dependent
2Measurement precision
If the device uses multiple image sensing devices and light emitting devices to detect operating environment, then the measurement precision and reliability are improved, but the use of energy increases
Solution Approach 1:
The light emitting device operates periodically rather than continuously, emitting light sources at intervals to illuminate the operating surface for the image sensing device. This periodic operation reduces energy consumption while still providing sufficient illumination for accurate detection of the operating environment
Solution Approach 2:
The processing circuit uses feedback from the image sensing device to control the operation of light emitting devices and image sensing devices. When the desired information is obtained (e.g., operating surface detected), the system reduces or stops emitting light, thereby reducing energy consumption while maintaining detection accuracy when needed
