Cross-Device Service Invocation for Camera-Limited Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices lacking or having weak target functions, such as cameras, cannot provide corresponding services to users due to hardware limitations or low battery levels.
Innovation Solution
A service invoking method and system that allows electronic devices to initiate a request for a target service from a peripheral device with a compatible application, enabling cross-device functionality and adaptive conversion of service types to provide an imperceptible user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an electronic device lacks target function hardware (e.g., camera), then the device structure is simpler and cost is lower, but the device cannot provide corresponding services (e.g., photography service)
Solution Approach 1:
The patent introduces a service invoking mechanism that acts as an intermediary between the first electronic device (without camera) and the second electronic device (with camera). The first device sends an invoking request to the second device, which provides the camera service through a shared connection. This allows the first device to access camera functionality without physically possessing the camera hardware, resolving the contradiction between service capability and hardware complexity.
2Ease of operation
If a user manually selects and operates the second application on the second electronic device, then the service can be provided, but the operation process becomes complex and time-consuming
Solution Approach 1:
The patent implements preliminary action by automatically starting the second application on the second electronic device in response to receiving an invoking request. Instead of requiring the user to manually launch and configure the second application, the system pre-establishes the necessary service connection and interface before the user needs to use the camera service, thereby simplifying operation and reducing time loss.
Solution Approach 2:
The system performs self-service by automatically establishing the connection between the first and second electronic devices, automatically starting the second application, and automatically transferring control for the camera operation. The service invocation process handles its own setup and configuration without requiring manual user intervention in these preliminary steps, making the system easier to operate and faster to respond.
3Ease of operation
If the first electronic device automatically receives and processes information from the second application, then the service experience is seamless, but the device complexity and data processing requirements increase
Solution Approach 1:
The patent uses an information processing interface as an intermediary between the second application and the first application. This interface layer handles the automatic receiving, converting, and processing of information from the second application, shielding the first device from the complexity of direct integration with the second application's internal structures. The intermediary manages data format conversion and processing requirements, enabling seamless user experience while containing complexity in a dedicated layer.

AI summary
Methods, devices, and system are provided. A method applied a first electronic device includes sending an invoking request of a target service to a second electronic device in response to a first operation that a user invokes the target service in a first application, where the invoking request indicates the second electronic device to use a second application to provide the target service, in response to a second operation performed by the user on the second application in the first electronic device or the second electronic device, automatically receiving first information that is generated by the second application and that is sent by the second electronic device, and displaying second information in the first application based on the first information where the second information is the same as or different from the first information.
