Solution Overview
Problem
Surveillance systems, particularly CCTV systems, face challenges in efficiently searching through large accumulations of video footage and event data, necessitating improved user interfaces for convenient retrieval of specific videos or events by date, time, and type.
Innovation Solution
A search device with a user-friendly interface that includes a time control interface featuring concentric circular shapes for AM and PM inputs, allowing users to easily specify time conditions, along with touch and gesture recognition for intuitive date and time selection, enabling efficient retrieval of videos and events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional multi-stage input interfaces are used for searching videos and events, then each parameter can be specified individually, but the user interface complexity and operation time increase significantly
Solution Approach 1:
The patent combines multiple time specification parameters (hour, minute, AM/PM) into a single circular control interface that resembles an analog clock. Users can specify the entire time by simply pointing at the desired position on the circle, eliminating the need to navigate through multiple separate input stages for each time parameter.
Solution Approach 2:
The patent transforms the traditional linear or hierarchical time input method into a two-dimensional circular interface. This dimensional change allows users to simultaneously specify multiple time parameters (hour and minute) by selecting a single position on the circle, where the radial position represents minutes and the angular position represents hours.
2Productivity
If multiple separate input stages are required for date and time specification, then each parameter can be accurately entered, but the total search time and user effort increase
Solution Approach 1:
The patent merges date and time specification into a unified interface where both can be specified simultaneously. The circular time interface allows users to set both the time of day and the date in a single interaction sequence, dramatically reducing the total time required for parameter input compared to traditional multi-stage approaches.
3Measurement precision
If detailed time parameters are specified through multiple stages, then search precision can be achieved, but the user experience becomes cumbersome and complex
Solution Approach 1:
The patent uses a circular interface where the radial distance from the center represents minute precision (0-60 minutes), while the angular position around the circle represents hour precision (0-12 hours). This dimensional mapping allows users to achieve precise time specification by simply pointing at a position on the circle, maintaining measurement precision while dramatically improving ease of operation.
Solution Approach 2:
The patent employs a circular (spheroidal in 2D) interface for time specification instead of linear sliders or separate input fields. The curved geometry naturally maps to the cyclical nature of time (hours 0-12, minutes 0-60) and allows users to specify precise time values through intuitive pointing gestures, combining precision with user-friendliness.
