Solution Overview
Problem
Conventional user interfaces for remotely controlling critical vehicle features are difficult to use and prone to accidental activation or deactivation, especially for non-technical users, leading to potential safety issues and user inconvenience.
Innovation Solution
An electronic device equipped with a haptic device that receives tactile gestures, such as an L-shaped swipe input, to intuitively control critical vehicle features like engine start/stop, door lock/unlock, and HVAC, preventing accidental activation/deactivation through a predetermined pattern of swipe inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional user interfaces are used for remote control, then the device is simple to manufacture, but the interface is difficult to use and prone to accidental activation
Solution Approach 1:
The patent transitions from traditional 2D touchscreen interfaces to a haptic device that detects 3D tactile gestures. Users perform tactile gestures in three-dimensional space (e.g., rubbing motions with different pressures, directions, and patterns), adding spatial and temporal dimensions to the interaction. This dimensional expansion makes the interface more intuitive and less prone to accidental activation while maintaining ease of use.
Solution Approach 2:
The patent replaces conventional mechanical or touchscreen-based input mechanisms with a haptic sensing system. Instead of relying on visual displays and touchscreens that require precise tapping or swiping, the system uses haptic sensors to detect tactile gestures through mechanical skin contact. This substitution enables more natural, intuitive control while reducing the complexity of the user interface design.
2Reliability
If simple input methods are used, then the operation is easy, but accidental activation occurs frequently
Solution Approach 1:
The patent implements dynamic gesture recognition that adapts to different user intentions. The haptic device detects multiple gesture parameters including direction, pressure, duration, and pattern of tactile movements. By analyzing the dynamic characteristics of each gesture rather than relying on static input methods, the system accurately distinguishes between intentional control actions and accidental touches, thereby improving reliability without compromising ease of use.
Solution Approach 2:
The system incorporates feedback mechanisms where the haptic device provides tactile response to user gestures. This feedback loop allows users to confirm their input intentions through the haptic response, reducing accidental activations. The feedback principle enhances both reliability by confirming intentional gestures and maintains ease of use through natural tactile interaction.
3Reliability
If PINs or passwords are required for control, then security is improved, but the operation becomes more complex and time-consuming
Solution Approach 1:
The patent implements preliminary authentication through biometric data collection and analysis. Instead of requiring PINs or passwords at the moment of control, the system performs preliminary verification by analyzing unique tactile characteristics of the user's gestures (such as pressure patterns, rhythm, and movement dynamics). This preliminary action establishes security credentials in advance, eliminating the need for time-consuming authentication during actual vehicle control operations.
Solution Approach 2:
The system uses self-service authentication where the user's own tactile gestures serve as the authentication mechanism. The haptic device analyzes the unique characteristics of the user's natural gestures to verify identity and authorization. This self-service approach eliminates the need for separate authentication steps, reducing time loss while maintaining security through biometric-like gesture recognition.

AI summary
An electronic device and a method for remote control of vehicle features are provided. The electronic device receives a first user input indicative of a selection of a first vehicle from a set of vehicles associated with a user. The electronic device further receives, via a haptic device associated with the electronic device, a second user input including a tactile gesture. The second user input is indicative of an instruction to remotely control a first set of features on the selected first vehicle. The tactile gesture includes a first swipe input along a first direction associated with the haptic device and further includes a second swipe input along a second direction perpendicular to the first direction. The electronic device further controls the first set of features on the selected first vehicle based on the received second user input.
