Input Pen Gesture Control via Gyro Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it difficult to perform input operations on touch-sensitive displays, such as shifting, zooming, and rotating, while holding an input pen, as these operations require both hands, leading to inconvenience in interacting with digital content on devices like tablets and smartphones.
Innovation Solution
An input pen with a sensor, such as a 3-axis gyro sensor, and a controller, connected via Bluetooth, allows for the detection and transmission of gestures to an electronic device, enabling operations like shifting, zooming, and rotating by mapping specific pen movements to corresponding commands stored in the device's memory, allowing for one-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users perform input operations (shifting, zooming, rotating) on touch-sensitive displays using fingers, then these operations can be performed accurately, but users cannot perform these operations while holding an input pen
Solution Approach 1:
The patent introduces an intermediary device (acceleration sensor or gyro sensor) that mediates between the input pen gestures and the display operations. The sensor detects pen movements and converts them into control signals that the electronic device interprets as input operations, enabling users to perform shifting, zooming, and rotating operations while holding the pen without needing to use their other hand
Solution Approach 2:
The patent replaces the mechanical finger-based touch input system with a sensor-based detection system. Instead of requiring physical finger gestures on the display surface, the acceleration sensor or gyro sensor detects the motion and orientation of the input pen itself, converting physical pen movements into digital control signals that trigger display operations
2Productivity
If users use fingers to perform input operations on the display, then both hands are required for operations like shifting and zooming, but this reduces operational efficiency
Solution Approach 1:
The acceleration sensor acts as an intermediary that translates input pen movements into display control operations, enabling single-handed operation. Users can hold the pen in one hand and perform all input operations (shifting, zooming, rotating) by moving the pen, eliminating the need to use the other hand for gesture operations
Solution Approach 2:
The input pen becomes self-sufficient by incorporating the acceleration sensor or gyro sensor directly into its structure. The pen detects its own movements and orientations and automatically generates the corresponding control signals, eliminating the need for users to manually operate additional controls or use their other hand for gesture input
3Adaptability or versatility
If no sensor is integrated in the input pen, then the pen structure remains simple, but gesture-based control operations cannot be detected
Solution Approach 1:
The patent makes the input pen multi-functional by integrating the acceleration sensor or gyro sensor into its structure. The same pen that is used for writing or drawing now also functions as a gesture controller for display operations, enabling shifting, zooming, and rotating capabilities without requiring separate control devices
Solution Approach 2:
The patent changes the physical parameters of the input pen by incorporating sensors that detect motion and orientation parameters. The acceleration sensor measures linear acceleration along three axes, while the gyro sensor measures angular velocity, enabling the pen to detect gestures such as shaking, rotating, and tilting that were previously undetectable
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
Enables seamless one-handed interaction with digital content by allowing users to perform gestures like shifting, zooming, and rotating without the need to hold the input pen, enhancing user experience and reducing operational complexity.
Implementation Method 1
The input pen may include a sensor (e.g., gyro sensor) and a controller. In one example, the sensor may be disposed into a cap of the input pen.

AI summary
In one example, an input pen to control an operation of a display is described, which may include a sensor to detect an input pen gesture, a communication interface to establish a connection with the display, and a controller to transmit a control signal corresponding to the detected input pen gesture to the display via the communication interface. The control signal may be used to retrieve a gesture command to manipulate data on the display.
