Side Display Pressure Sensing for Unintended Touch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In information processing apparatuses with side surface displays, users often unintentionally trigger operations when holding the device, leading to undesired processing.
Innovation Solution
Incorporating pressure-sensitive sensors and a control section that differentiate between operation and holding actions based on pressure values, allowing accurate identification of user intent and preventing unintended processing by determining the status of the operation area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display is arranged on the side surface of the housing, then the user can access additional interface options, but the user may unintentionally trigger operations when holding the device
Solution Approach 1:
The patent applies parameter changes by monitoring pressure value parameters over time to differentiate between holding and operating states. The control section analyzes pressure magnitude and duration thresholds to determine user intent, transforming a single parameter (pressure) into a reliable operation detection mechanism that prevents accidental triggers while maintaining side surface display functionality
2Measurement precision
If the pressure-sensitive sensor detects pressure on the sub-surface, then the system can identify user contact, but it cannot distinguish between holding and operating actions
Solution Approach 1:
The patent applies dynamics by transitioning from static pressure detection to dynamic pressure analysis over time. The control section continuously monitors pressure values and evaluates changes across multiple time points, enabling the system to distinguish between sustained holding actions and deliberate operating actions based on the temporal dynamics of pressure application
3Speed
If the control section executes processing based on pressure detection, then user operations are responsive, but unintended processing occurs when the user merely holds the device
Solution Approach 1:
The patent applies preliminary action by establishing pressure thresholds and time duration criteria before executing operations. The control section preliminarily evaluates whether detected pressure meets both magnitude and temporal criteria before triggering any processing, ensuring that only valid operating actions result in system responses while maintaining rapid execution speed for genuine operations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents unintended processing when the user holds the device, ensuring accurate identification of operation and holding states, thus ensuring user-intended actions are executed.

AI summary
An information processing apparatus according to the present technology includes a housing, a display section, a pressure-sensitive sensor, and a control section. The housing has a front surface and a sub-surface including an operation area and is capable of being held by a user. The display section is arranged on the front surface. The pressure-sensitive sensor detects a pressure value with respect to the sub-surface. The control section identifies a status that the operation area is operated by the user and a status that the operation area is held by the user on the basis of the pressure value, and executes predetermined processing on the basis of an operation by the user with respect to the operation area in a case where the status is determined that the operation area is operated.
