Solution Overview
Problem
Existing machine-human interfaces often distract users by occupying senses like hearing or sight, and are unsuitable for high distraction environments or situations requiring attention to real-world surroundings, posing challenges for individuals with disabilities such as hearing loss or vision impairment.
Innovation Solution
A system utilizing electro-tactile stimulation to communicate sensory information through electrical signals to nerves, allowing users to perceive messages and inputs via tactile sensations, combined with visual and auditory cues, enabling communication and interaction without relying on vision or hearing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional machine-human interfaces (visual/auditory) are used, then information can be communicated effectively, but user distraction increases and accessibility for individuals with disabilities deteriorates
Solution Approach 1:
The patent segments the communication channel by introducing a separate tactile feedback mechanism (vibration motor) that operates independently from visual and auditory channels. This allows information to be conveyed through a different sensory modality, reducing competition for attentional resources and improving accessibility for users with visual or auditory impairments without sacrificing communication effectiveness.
Solution Approach 2:
The vibration motor acts as an intermediary device that translates digital signals into tactile sensations. This intermediary converts information from forms that may be inaccessible to certain users into tactile feedback that can be perceived through touch, thereby mediating the communication between the system and users with different abilities while maintaining effective information transfer.
2Adaptability or versatility
If sensory augmentation through multiple channels is implemented, then information accessibility improves, but device complexity increases
Solution Approach 1:
The processing system is designed to handle multiple types of input signals (visual, auditory, tactile) and translate them into appropriate output modalities. This multi-functional approach allows a single system to serve diverse user needs and accessibility requirements without requiring separate dedicated systems for each sensory channel, thereby improving adaptability while managing complexity through integration.
Solution Approach 2:
The system dynamically adjusts the type, intensity, and pattern of tactile feedback based on the input signal characteristics and user needs. By varying parameters such as vibration frequency, amplitude, and duration, the system can convey different types of information through a single tactile channel, achieving multi-functionality without proportionally increasing hardware complexity.

AI summary
In some examples, a system includes a hub comprising a processor and memory. The hub is configured to store data in the memory regarding a context environment, determine and maintain an indication of a relative position of multiple items in the context environment, determine and maintain a relative position of a first user in the context environment, and maintain a digital representation of a location of the first user in the context environment in the data responsive to the first user exiting the context environment.
