Solution Overview

Problem

Existing technologies fail to accurately evaluate user interest in content displayed on information processing terminals, as they rely solely on time spent viewing content, which does not account for user concentration levels during input operations and non-operation periods.

Innovation Solution

A system that detects movement amounts using sensors on the information processing terminal, evaluating interest based on operation and non-operation periods, with weight coefficients adjusting the influence of movement on interest evaluation, allowing for quantitative assessment of user interest over time.

VSEngineering Contradiction Analysis

1Measurement precision

If user interest is evaluated based solely on time spent viewing content, then the evaluation method is simple, but the measurement precision of user interest is insufficient

Engineering Contradiction:
Improveuser interest evaluation accuracyVSAvoidevaluation system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The viewing period is segmented into operation periods (when input operations are detected) and non-operation periods (when no input operations are detected). Movement amounts are separately evaluated for each period type, and these evaluations are combined using weight coefficients to produce the final user interest evaluation. This segmentation allows the system to capture different aspects of user engagement (active interaction vs. passive viewing) with appropriate measurement criteria for each.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system changes the parameter of movement amount evaluation by applying different weight coefficients (Wd for operation periods, Wnop for non-operation periods) to different viewing conditions. This parameter adjustment allows the same movement amount to be interpreted differently based on the operational context, thereby improving the precision of user interest evaluation without requiring entirely different measurement systems.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If movement amount detection is used to evaluate user concentration, then measurement precision improves, but device complexity increases due to additional sensors and processing

Engineering Contradiction:
Improveuser concentration measurement accuracyVSAvoidsensor and processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The movement amount detection sensor serves multiple functions: it detects terminal movement during content viewing, distinguishes between operation and non-operation periods through movement patterns, and provides data for both real-time user interest evaluation and historical analysis. This multi-functionality reduces the need for separate dedicated sensors for each measurement task, thereby limiting the increase in device complexity while maintaining high measurement precision.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses the information processing terminal's own movement detection capabilities to evaluate user interest, rather than requiring external monitoring devices. The terminal self-services by utilizing its built-in sensors to generate the data needed for user engagement analysis, reducing external device requirements and simplifying the overall system architecture.

Inventive Principle:
Principle #25Self-service

AI summary

A computer-readable recording medium storing an intensity of interest evaluation program that causes a computer to execute a procedure is provided. The procedure includes: using a movement amount detection sensor installed to an information processing terminal to detect a value of a movement amount of an information processing terminal in a period in which content is being displayed on the information processing terminal; and evaluating a intensity of interest toward the content based on a length of a first period within the period in which the detected value of the movement amount of the information processing terminal is a predetermined value or less.
