Solution Overview
Problem
Portable electronic devices face limitations in display size, leading to increased typographical errors and inefficiencies with soft keyboards, particularly when changing keyboard layouts or using remote input modes.
Innovation Solution
An electronic device equipped with a projection module and a detachable touch sensing device that dynamically adjusts soft keyboard layouts based on user input methods, switching between touch and remote input modes, and compensates for input errors.

1Length of moving object
If a soft keyboard is used on portable electronic devices with limited display size, then the device maintains portability, but input accuracy decreases and typographical errors increase
Solution Approach 1:
The patent projects the soft keyboard from the two-dimensional display screen onto a three-dimensional external surface (such as a table or desk). This dimensional transition allows the keyboard to be displayed in a larger physical space while maintaining the portability of the electronic device itself. The projection creates a virtual keyboard overlay that extends beyond the constraints of the device's display area, thereby improving input accuracy without requiring a larger screen.
2Manufacturing precision
If a larger display is used to improve input accuracy, then typographical errors decrease, but device portability and compactness are compromised
Solution Approach 1:
The patent introduces an external projection surface as an intermediary between the electronic device and the user's input interaction. Instead of enlarging the device's display, the system projects the keyboard layout onto an external surface (table, desk, or other flat surfaces). This intermediary approach allows the keyboard to be displayed at a larger effective size for improved accuracy while the device itself remains compact and portable.
3Device complexity
If manual manipulation of soft keyboard settings is required to change layout or configuration, then device complexity is reduced, but ease of operation decreases
Solution Approach 1:
The patent enables the soft keyboard to automatically adapt and reconfigure based on the projected surface characteristics. The system detects properties of the projection surface (such as size, shape, and orientation) and automatically adjusts the keyboard layout, key size, and arrangement without requiring manual user intervention. This self-service capability allows the keyboard to optimize its configuration for different surfaces and usage scenarios, significantly improving ease of operation while maintaining relatively simple device architecture.
Solution Approach 2:
The patent implements dynamic keyboard layout adjustment where the soft keyboard automatically reconfigures based on real-time detection of projection surface properties. The system can dynamically change key sizes, spacing, and arrangement to match the projected area and usage context. This dynamic adaptation eliminates the need for manual settings while keeping the device itself simple, as the complexity is handled through automated environmental sensing and response.

AI summary
Disclosed is an electronic device including a projection component. The electronic device identifies whether a touch sensing device configured to detachably couple to the electronic device is coupled to the electronic device to sense a touch input of a user on a soft keyboard. Based on identification that the touch sensing device is coupled to the electronic device, the electronic device controls the projection component to project a soft keyboard corresponding to a first keyboard layout on a projection plane.
