Haptic Belt Alerts for HMD Sensory Overload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted displays (HMDs) often overwhelm users with information, leading to sensory overload and reduced situational awareness, especially in critical situations where rapid processing and decision-making are essential.
Innovation Solution
A system and method that utilize haptic devices integrated into a belt or armband to provide tactile alerts, complementing visual and auditory alerts, allowing for the presentation of information across multiple sensory modalities to enhance situational awareness and reduce sensory overload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual and auditory alerts are used in HMDs, then information presentation capability is improved, but sensory overload increases
Solution Approach 1:
The patent introduces tactile feedback as a third dimension of information presentation, moving beyond traditional visual and auditory modalities. Haptic devices provide force feedback through the user's body, creating a new sensory dimension for alert delivery that distributes information across multiple sensory channels and reduces overload in any single modality.
Solution Approach 2:
The patent segments alert information across multiple sensory modalities (visual, auditory, and tactile) rather than concentrating all alerts in one modality. Different types of alerts are distributed to different senses based on their nature and urgency, with tactile feedback handling certain categories of alerts separately from visual and auditory channels.
2Reliability
If multiple alert modalities are used, then situational awareness is improved, but device complexity increases
Solution Approach 1:
The patent implements a unified alert management system that controls multiple modalities (visual displays, auditory speakers, and tactile haptic devices) through a single integrated controller. This multi-functional approach allows one system to manage diverse alert delivery mechanisms, improving situational awareness while avoiding the complexity of separate independent systems for each modality.

AI summary
An information handling system enhances end user situational awareness by selectively presenting sensed environmental conditions with tactile feedback, such as with haptic device output at a band worn on the end user's body. Tactile trigger rules apply sensed conditions to detect events that trigger a haptic device notification, such as a threat to the end user in a tactical situation that is not in the field of view of a head-mounted display or that has a lower level of significance relative to other identified threats.
