Solution Overview

Problem

Existing user interfaces that integrate hardware buttons in electronic devices are often cumbersome, inefficient, and complex, leading to increased device size, weight, and cost, as well as cognitive burden and energy waste, particularly in battery-operated devices.

Innovation Solution

Implementing a system that uses hardware buttons to control camera functions with distinct criteria for capturing media with and without synthetic depth-of-field effects, and adjusting user interface elements based on button press characteristics, reducing the need for frequent switching and enhancing user interaction efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If numerous hardware buttons are integrated into the electronic device, then the control functionality is enhanced, but the device size, weight, and cost increase

Engineering Contradiction:

Improvecontrol functionalityVSAvoiddevice weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent implements a multi-functional hardware button that can perform different functions based on the active application or context. The same physical button serves as a shutter in camera mode, a navigation control in map mode, and other functions in different applications, eliminating the need for multiple dedicated buttons while maintaining comprehensive control functionality across all applications

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent creates a virtual representation of the hardware button within the software interface that mirrors the physical button's functionality. This virtual button allows users to access the same controls through software when the physical button is not needed, reducing the need for additional physical buttons while maintaining full control capability

Inventive Principle:

Principle #26Copying

2Adaptability or versatility

If numerous hardware buttons are integrated into the electronic device, then the control functionality is enhanced, but the device complexity increases

Engineering Contradiction:

Improvecontrol functionalityVSAvoidinterface complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic button functionality where the same physical button adapts its purpose based on the current application state. The button's function changes dynamically according to context - serving as a shutter button in camera applications, a navigation control in map applications, and other functions in different contexts - thereby providing diverse control capabilities without requiring multiple static buttons

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent creates a universal control mechanism where a single hardware button can perform multiple functions across different applications. The system provides a unified button interface that contextually adapts to serve various control needs, reducing interface complexity while maintaining comprehensive adaptability

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Area of stationary object

If displayed software controls are used instead of hardware buttons, then the device size is reduced, but the user interaction becomes slower and more error-prone

Engineering Contradiction:

Improvedevice sizeVSAvoidinteraction speed

Core Design Contradiction:

Area of stationary objectVSProductivity

Solution Approach 1:

The patent segments the control interface into two parts: essential frequently-used functions are assigned to physical hardware buttons for rapid access, while less critical functions remain in the software interface. This segmentation allows the device to maintain a compact size while providing fast physical controls for important operations, thereby balancing device size with interaction speed

Inventive Principle:

Principle #1Segmentation

4Adaptability or versatility

If frequent switching between software controls and hardware buttons is required, then the control versatility is enhanced, but the cognitive burden and energy consumption increase

Engineering Contradiction:

Improvecontrol versatilityVSAvoidenergy consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by stationary object

Solution Approach 1:

The patent merges the hardware button controls with the software interface so that they work together harmoniously rather than requiring separate interaction modes. The physical buttons are integrated into the application context, allowing users to access versatile control functions through a unified interface that reduces cognitive load and minimizes the need for switching between different control paradigms, thereby reducing energy consumption

Inventive Principle:

Principle #5Merging (Combining)

AI summary

User interfaces integrating one or more hardware buttons are described, including camera user interfaces that perform different media capture operations (e.g., different types of captures, synthetic depth-of-field operations, and/or changes to the camera user interface) in response to presses of different buttons and/or in response to different types of button presses, user interfaces that provide different responses to button presses inside and outside of a camera application, and user interfaces that provide different settings functions in response to different types of button presses.
