Smart Mobile Device Side Sensors for Two-Handed Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional smart mobile communication devices, such as smartphones, require users to operate them with only one hand, limiting convenience for tasks like navigating, gaming, and web browsing due to the reliance on a single touch screen interface.
Innovation Solution
Incorporating two sensors on opposite holding surfaces as secondary operation interfaces, allowing users to perform shortcut commands like volume adjustment, page rolling, and mode changes, in addition to the primary touch screen interface for main operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single touch screen interface is used for all operations, then the device structure remains simple, but the ease of operation deteriorates when using one hand
Solution Approach 1:
The operation interface is segmented into multiple independent components: a primary touch screen for main operations and secondary sensors positioned on opposite holding surfaces for auxiliary operations. This segmentation allows different hand positions and input methods to be utilized simultaneously, improving ease of operation without requiring a complete redesign of the device structure.
Solution Approach 2:
The patent extends the operation interface from a single two-dimensional touch screen to a three-dimensional arrangement by placing sensors on the holding surfaces (sides) of the device. This dimensional expansion enables users to operate the device with both hands in different positions, transforming the interaction from planar to spatial and significantly improving ergonomics.
2Productivity
If only the touch screen is used for operations, then the device design remains compact, but the productivity deteriorates for tasks requiring multi-finger input
Solution Approach 1:
The holding surfaces of the device are given multiple functions: they serve both as structural components for holding the device and as locations for secondary operation interfaces. This multi-functionality allows the same physical space to support both device structure and additional input capabilities, enhancing productivity without proportionally increasing device complexity.

AI summary
A smart mobile communication device comprises a casing, a touch screen and two sensors. The casing has a front surface and at least two opposite holding surfaces. The front surface is disposed between the at least two opposite holding surfaces. The touch screen is disposed on the front surface to be used as a main operation interface of the smart mobile communication device. The two sensors are disposed on the at least two opposite holding surfaces respectively to be used as secondary operation interfaces of the smart mobile communication device. Accordingly, the convenience for operating the smart mobile communication device can be enhanced.
