Solution Overview
Problem
Existing calibration processes for movable objects, such as drones, lack sufficient workability and assistance for users in correctly orienting and positioning the object for effective operation.
Innovation Solution
A movable object, like a drone, equipped with a notification unit and control unit to provide assistance information through light sources and sound output, helping users with orientation, positioning, and work progress, including calibration of sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If calibration work instructions are displayed only on a screen, then information can be presented to the user, but the user must continuously refer to the screen while performing physical operations, reducing workability
Solution Approach 1:
The patent introduces light sources as an intermediary medium to convey calibration instructions. Instead of requiring the user to read screen instructions while performing physical operations, the system projects light patterns (such as arrows or highlighted areas) directly onto the movable object's surface, serving as a visual mediator that guides the user's hands during calibration tasks.
Solution Approach 2:
The patent replaces the mechanical/visual system of screen display with an optical projection system. By using light sources to directly illuminate or project guidance patterns onto the object, the system substitutes the need for screen-based mechanical reading with an optical field-based guidance mechanism that integrates information directly into the work space.
2Ease of operation
If the notification unit provides detailed assistance information, then workability improves, but the device complexity increases due to additional light sources and control mechanisms
Solution Approach 1:
The patent makes the notification unit multi-functional by enabling it to display various types of calibration instructions through different light patterns. The same light source system can show orientation arrows, highlight target areas, indicate progress stages, or provide error warnings, eliminating the need for separate display devices for each type of information.
Solution Approach 2:
The patent combines the notification function with the existing structural elements of the movable object. Rather than adding separate complex display devices, the system integrates light sources into the object's housing or surface, merging the notification system with the object's existing form factor and reducing overall system complexity.
3Measurement precision
If the calibration process requires multiple steps and precise orientation, then measurement precision improves, but the time required for calibration increases
Solution Approach 1:
The patent implements a feedback mechanism where the notification unit continuously provides visual cues about the current calibration state. As the user adjusts the object's orientation, the light sources dynamically update to show whether the correct position is being approached, providing real-time feedback that accelerates the precision-oriented calibration process.
Solution Approach 2:
The patent uses light sources to pre-indicate the target orientation or position before the user completes the adjustment. By showing the desired end state in advance through projected patterns or illuminated markers, the system guides the user's preliminary actions toward the correct calibration position, reducing trial-and-error time.

AI summary
A movable object according to an embodiment of the present technology includes a body unit, a notification unit, and a notification control unit. The notification unit is provided in the body unit. The notification control unit controls an operation of the notification unit, to thereby notify of information regarding at least one of an orientation of the body unit or a position on the body unit as assistance information for assisting work of a user on the movable object. This enables the user to intuitively recognize which orientation the user should put the body unit in, and the workability in user's work can be improved.
