Input/Output For User-Computer Interaction TRIZ Cases

Camera-based driver monitoring uses gaze, hand position, and passenger presence to enable vehicle HMIs only when steering engagement is confirmed.

Camera-based occupant detection restricts passenger access to the driver screen and enables see-through display output that preserves forward vision.

Magnetic levitation and docking let one vehicle interface provide high freedom of use while maintaining stable, compliant operation.

A camera-triggered shy button hides passenger controls until needed, preserving cockpit aesthetics and the driver's forward view.

Dual return means keep the movable part calibrated after installation changes, preserving haptic feedback and force measurement accuracy.

A deflectable vehicle touch display measures press force by distance change, preventing accidental activation without complex force sensors.

Tactile feedback in a glucose management interface helps users adjust insulin discreetly, avoid dosing limits, and improve control.

A cushioning layer thicker than the housing gap nests into the housing to keep the vibration structure thin without restraining the vibrator.

External cameras, image recognition, and voice, gaze, or touch input let drivers identify roadside objects and act on them without distraction.

Multiple vibration transfer parts convert in-plane motion into out-of-plane ultrasonic haptics, improving tactile feedback and texture recognition.

A sensing module and control unit calibrate movable-part motion to deliver precise, varied tactile feedback beyond basic vibration.

By placing speakers inside keyboard keys, laptops free housing space for other components while improving loudness and frequency response.

User-selectable gesture thresholds help powered vehicle closure panels avoid false activation while preserving reliable non-contact opening.

Temple ground areas and electronic components act as antennas, saving space in lightweight wearables while maintaining wireless communication.

A dielectric overmold isolates a metal button cap during sensing, then allows ESD coupling at high voltage to protect measurement accuracy.

Rotating left and right steering wheel grips replaces lateral movement mechanisms, simplifying structure while opening driver space.

An inclined insulating layer and stepped electrode shape the functional layer thickness to suppress current leaks, stray emission, and noise.

Vehicle cameras recognize gesture passwords and commands, enabling secure remote access and control without key-fob UI limits or mobile apps.

Seat position and orientation define a likely 3D head zone, helping vehicle tracking reject outliers and cut latency under changing light.

Gaze-based seat rotation aligns occupants with cabin-mounted vehicle components, improving reachability as controls spread beyond the instrument panel.

Gaze detection highlights the intended touchscreen control with distinct haptics, helping drivers find complex in-vehicle UI elements with less visual attention.

A continuous touch surface combines force sensing, spring support, and electromagnetic haptics to detect input and deliver normal oscillation feedback.

A magnetorheological elastomer vibration unit uses magnetic-field tuning and dual injection to deliver thin, low-energy, localized haptic patterns.

A delayed self-resetting ionic signal lets a hybrid synaptic circuit implement three-factor plasticity with far lower energy than CMOS.

An arched elastic layer boosts stiffness and rebound speed in polymer pressure sensors, reducing creep and hysteresis after unloading.

Selective switch lighting on a steering wheel highlights likely functions while hiding inactive icons to balance operability, appearance, and energy use.

Pressure sensors beneath each key capture force levels as well as key presses, enabling richer and more precise keyboard input.
