Virtual Artifacts on Mobile Devices for Tactile Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As mobile devices shrink in size, they often eliminate physical controls, leading to a lack of tactile feedback for users interacting with virtual interfaces, which can be inconvenient for eyes-free operation and may not provide the same user experience as physical controls.
Innovation Solution
Implementing virtual artifacts on mobile devices using a combination of motion and touch inputs, leveraging touchscreen and motion sensing technologies to mimic physical controls like buttons, dials, sliders, and switches, and providing feedback through visual, auditory, and haptic means to enhance user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If mobile devices eliminate physical controls to shrink in size, then device compactness is improved, but tactile feedback for users is lost
Solution Approach 1:
The patent replaces physical mechanical controls with virtual controls on a touchscreen display. Motion sensors detect device movements and translate them into control inputs, substituting the mechanical interaction of physical buttons with a combination of visual display and inertial sensing. This allows the device to maintain compact size while providing control functionality through motion-based virtual artifacts.
Solution Approach 2:
The patent implements feedback mechanisms where the touchscreen display shows visual representation of virtual controls and their states. Motion sensor data provides feedback about device orientation and movement, allowing users to understand the state of virtual controls through visual and motion cues, compensating for the lack of tactile feedback from physical controls.
2Device complexity
If physical controls are removed from mobile devices, then device simplicity is improved, but user interaction intuitiveness deteriorates
Solution Approach 1:
The patent creates virtual copies of physical controls (buttons, dials, sliders, switches) that are displayed on the touchscreen. These virtual artifacts replicate the appearance and functional behavior of their physical counterparts, allowing users to interact with familiar control types through touch and motion gestures, thereby maintaining interaction intuitiveness despite the removal of physical controls.
Solution Approach 2:
The patent makes the virtual controls dynamic by linking them to real-time motion sensor data. As the user moves or tilts the device, the virtual controls respond dynamically to reflect the current device state, creating an intuitive and responsive interaction experience that adapts to user actions without requiring physical components.
