Voice-Activated Smart Card with LED and Vibration for Location

The patent applies color changes by incorporating light-emitting components (LEDs) that emit different colors to indicate different card states or types. This allows users to quickly distinguish between multiple cards based on color signals without having to physically examine each card, thereby reducing the time to locate a specific card while maintaining a large quantity of cards.

The patent incorporates vibration motors that generate mechanical vibrations to attract user attention to a specific card. When a card needs to be located, the corresponding card vibrates, creating a distinctive tactile signal that helps users quickly identify and retrieve the desired card from among many cards without time-consuming manual search.

The patent applies local quality by adding distinctive features (light-emitting components and vibration motors) to specific locations on or within individual cards. This allows each card to maintain the same overall shape and size for uniform storage, while possessing unique local characteristics through colored lights or vibration capabilities that enable easy distinction and location of specific cards.

By incorporating vibration motors in specific cards, the patent creates a tactile differentiation mechanism. Cards with vibration motors can be activated to vibrate, providing a distinctive mechanical signal that helps users quickly identify and locate the desired card without compromising the uniform appearance and storage characteristics of the card deck.

The patent incorporates vibration motors as sensory-perceptible devices that provide tactile feedback to help users locate specific cards. While this adds some complexity to the card structure, the vibration mechanism is a relatively simple and reliable component that significantly improves card location ease by providing distinctive tactile signals that users can detect without visual inspection.

The patent uses light-emitting components (LEDs) that produce color changes or color-coded signals to indicate card identity or state. This visual differentiation method adds minimal structural complexity while greatly enhancing ease of operation, as users can quickly identify and locate specific cards by observing color signals from a distance or without handling each card.
