Engineering Scope
The development of low-power attitude reminder is oriented to the usage requirement of "attitude products need to recognize status and vibrate to remind", and the collection, processing, communication and power supply are designed as one set of products. The project can start from new main board development, existing firmware modification or designated module integration. The development scope is confirmed based on the target function, existing foundation and delivery requirements.
Interfaces and Product Integration
Develop IMU acquisition, attitude determination, stationary detection, reminder scheduling, parameter configuration and record synchronization.
Power Supply and State Scheduling
Sampling determines the posture, reminds after the duration is met, sets the reminder interval and retains the event.
Data and System Integration
Clarify the connection and data format around the IMU, wearing direction, vibration actuator and configuration interface, and define recording, transmission, confirmation and abnormal status.
Prototypes, Testing and Deliverables
Form posture processing, reminder rules, vibration drive and wearing sample records, focusing on verifying the sampling and wake-up strategy, number of reminders, false trigger power consumption and independent verification of the judgment effect.
System Architecture and Operation
Sampling determines the posture, reminds after the duration is met, sets the reminder interval and retains the event.
- Interface composition: IMU, wearing direction, vibration actuator and configuration interface.
- Work scheduling: Determine each status based on sampling, interaction and reception requirements, indicating which circuits continue to run.
- Exception handling: Define deadlines, bounded retries, and recovery behaviors for applicable communication, sensing, or execution tasks.
Design Conditions and Functional Limits
This service is intended for posture reminders and motion interaction. Detection rules and functional requirements are defined in the statement of work.
Define power targets together with functional requirements. Battery-life estimates must specify the battery, temperature, operating cycle, event frequency and network conditions. Keep estimates separate from continuous-operation test results.

Why should the number of reminders also be used as a power consumption parameter?+
Each vibration has action energy, and frequent false reminders will change the total power consumption. Algorithm false triggering, reminder intervals, and executor load need to be tested together.
Is it possible to develop only part of an existing product?+
Module development or power consumption optimization can be carried out according to the existing interface and modifiable range. For this product, you first need to check the IMU, wearing direction, vibration actuator and configuration interface, and then determine the scope of changes and regression.
How to determine the cost and period of this project?+
The evaluation is split based on delivery items such as posture processing, reminder rules, vibration drive, and wearing sample records; the prototype materials, structure, platform, external tests, and new functions are listed separately, and quotations and nodes are formed after the requirements and interfaces are confirmed.
