Object-Specific Action Activation via Movement Mimicry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video surveillance systems require cumbersome and unintuitive methods for activating object-specific actions, often necessitating different user input devices for various actions, which can be complex and inconvenient for operators.
Innovation Solution
A method that allows users to select a moving object in a video by mimicking its movement characteristics using a user input device, such as a joystick or gesture control receiver, and automatically activates object-specific actions like zooming or tracking, using image analysis and potentially ranging sensors for accurate determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different user input devices are used for different actions (clicking for tracking, joystick for PTZ), then the system can perform various object-specific actions, but the device complexity and ease of operation deteriorate due to requiring multiple devices and learning different control methods
Solution Approach 1:
The patent makes a single user input device (such as a joystick or gesture control receiver) perform multiple functions by detecting different movement characteristics. The same device can select moving objects, activate tracking, control PTZ cameras, and trigger other actions depending on how it is moved, eliminating the need for multiple specialized input devices and simplifying the user interface.
Solution Approach 2:
The system detects different movement characteristics (direction, speed, duration, magnitude) of the user input device to differentiate between various intended actions. By analyzing parameters such as movement direction vectors, speed thresholds, and temporal patterns, the system determines whether the user intends to select an object, activate tracking, or control camera positioning, all through a single device.
2Adaptability or versatility
If different user input devices are used for different actions, then various object-specific actions can be activated, but the device complexity increases due to requiring additional equipment
Solution Approach 1:
The patent makes a single user input device (such as a joystick or gesture control receiver) perform multiple functions by detecting different movement characteristics. The same device can select moving objects, activate tracking, control PTZ cameras, and trigger other actions depending on how it is moved, eliminating the need for multiple specialized input devices and simplifying the user interface.
Solution Approach 2:
The patent combines the functions of multiple input devices into a single device. By merging object selection, tracking activation, and camera control capabilities into one unified input mechanism, the system reduces hardware complexity while maintaining full functionality through intelligent interpretation of movement patterns.
3Ease of operation
If traditional selection methods are used (clicking on objects), then object selection can be made, but the ease of operation deteriorates when objects are small or moving quickly making precise clicking difficult
Solution Approach 1:
The patent introduces movement characteristic analysis as an intermediary between the user's input device movement and object selection. Instead of directly clicking on small or fast-moving objects, the user moves the input device, and the system uses the movement characteristics (direction, speed, trajectory) to identify and select the intended object, making the selection process more tolerant of imprecision.
Solution Approach 2:
The patent adds temporal and directional dimensions to object selection. Instead of relying solely on spatial precision (clicking coordinates), the system incorporates movement direction vectors, speed, and trajectory over time to determine which object the user intends to select, effectively using additional dimensions to compensate for reduced spatial precision requirements.

AI summary
A method of activating an object-specific action comprises obtaining, based on image analysis of acquired images, a plurality of values of a movement characteristic, each value representing a moving object detected in the acquired images; receiving an input signal from a user input device, wherein the input signal represents a value of the movement characteristic for the user input device; comparing the value of the movement characteristic for the user input device with each value of the movement characteristics for the moving objects, and determining the moving object corresponding to the closest value of movement characteristic as a selected moving object; and activating the object-specific action for the selected moving object.
