Problem
Current notification methods on mobile devices are disruptive, lack privacy, and fail to provide context-sensitive feedback, making it difficult for users to efficiently respond to social network updates and other digital notifications without interrupting their activities.
Innovation Solution
A haptic notification apparatus and method that uses a wireless module and haptic interface to transmit coordinated sensations on the skin, allowing users to receive and respond to notifications through tactile feedback, enabling silent and context-aware interaction with notifications from social networking and web applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional notification methods (audio, visual) are used, then users can be alerted to notifications, but the notifications become disruptive and lack privacy
Solution Approach 1:
The patent replaces traditional acoustic and visual notification systems with a haptic interface that uses tactile sensations delivered through the skin. The haptic interface transmits encoded notification information as coordinated tactile sensations, substituting mechanical vibration and electrical stimulation for sound waves and light displays, thereby eliminating disruptiveness while maintaining notification effectiveness.
Solution Approach 2:
The patent introduces a haptic interface as an intermediary between the notification system and the user. This interface encodes notification information into tactile patterns and transmits them through skin contact, serving as a private mediator that delivers information without the public disruptiveness of audio or visual signals.
2Productivity
If users manually unlock and respond to notifications using on-screen keyboard, then they can reply to messages, but the process is slow and interrupts user activities
Solution Approach 1:
The patent prepares multiple pre-configured response templates for common notification scenarios before they are needed. When a notification is received, the system presents these pre-prepared responses through the haptic interface, allowing users to select and send replies without manually composing messages, thereby dramatically reducing response time and minimizing interruption to ongoing activities.
Solution Approach 2:
The system automatically manages the notification response process by presenting pre-configured templates and handling the communication protocol. The user simply needs to select a response from the haptic interface, and the system completes the sending process, reducing the user's workload and time investment.
3Adaptability or versatility
If standard haptic feedback is used, then users receive tactile notifications, but the feedback cannot differentiate between different notification contexts or provide interface guidance
Solution Approach 1:
The patent segments notification information into distinct encoded haptic patterns that represent different notification types, urgencies, and contextual information. By dividing the information content into separate encodable elements and transmitting them as coordinated tactile sensations, the system achieves context-sensitive differentiation while managing encoding complexity through structured segmentation of the haptic signal.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to silently and efficiently receive and respond to notifications without interrupting their activities, providing context-sensitive haptic feedback that differentiates between message types and urgency, allowing for rapid and private interaction with minimal user intervention.
Implementation Method 1
Each electrode is provided with at least one insulator so as to prevent flow of direct current from the electrode to the skin and form a capacitive coupling between the electrode and the skin
Implementation Method 2
A haptic interface in the form of an array of electrodes configured to stimulate sensory nerves under the skin of a user when a current is applied to the electrodes
Data Source
AI summary
The present invention relates generally to a haptic notification apparatus and method which allows a user to be notified through a haptic interface allowing notifications to be perceived by a user as coordinated sensations. Preferably, the coordinated sensations are generated by providing a plurality of conducting electrode having at least one insulator per electrode, allowing skin nerve endings of user to be stimulated via capacitive coupling over said insulator. The apparatus and method also preferably includes a sensor which is configured to sense movement or rotation in any axis and sense electronic nerve signals or pressure from muscle contractions in order to allow a user to respond to a haptic notification.
