Pixel
A wearable system that reconstructs environmental awareness through touch, for Deaf and hard-of-hearing users

challenge
Most assistive technologies for Deaf and hard-of-hearing people translate sound into isolated alerts — single vibrations, visual notifications, binary signals. What is lost is not sound itself, but environmental awareness: direction, proximity, intensity, urgency. How might we restore awareness of the world around us without relying on hearing?
solution
A wearable haptic system distributed around the head. Through a 360° interface, the environment becomes a continuous tactile field surrounding the user. Direction becomes position on the headband. Intensity becomes pressure. Proximity becomes stimulus strength. Clarity becomes tactile definition. Pixel does not simulate hearing — it reconstructs spatial awareness through the body.
Sound is not information — it is spatial presence. Starting from this insight, Pixel reframes assistive technology from compensation to perceptual augmentation, proposing a shift in how accessibility is understood: not as the replacement of missing senses, but as the redesign of perception itself. Applicable to any context where environmental awareness is compromised — domestic, urban, or operational.
The 360° haptic interface distributes tactile stimuli around the full perimeter of the head, reconstructing the spatial quality of environmental sound. Haptic actuators are positioned to correspond to directional sound sources — creating an intuitive, learned perceptual map of the surrounding environment. The result is not a notification system. It is a continuous field of awareness the user inhabits.
Existing assistive systems correct a deficit. Pixel proposed something structurally different: translating the spatial properties of sound — direction, proximity, intensity, urgency — into a continuous haptic field. The body becomes a sensing interface, not a receiver of alerts. A shift that changes not just the tool, but the relationship between the user and their environment.
01
Research
The gap is not silence, but disconnection
The starting point was a deceptively simple observation: what Deaf and hard-of-hearing people lose is not just sound, but the spatial structure that sound creates — the awareness of direction, proximity, and urgency that orients us in our environment. In domestic settings especially, this absence creates a constant sense of disconnection from the surrounding world. That reframing — from silence to spatial disconnection — became the brief.

Concept
From alerts to spatial fields
Existing assistive systems work by converting sound into discrete notifications — a vibration, a flash, a signal. Pixel proposed something different: instead of replacing sound with alerts, translate its spatial properties into a continuous tactile field. Direction, proximity, intensity, urgency — all present simultaneously, all navigable through the body.

Design
A 360° haptic interface
The headband form factor was selected for its capacity to distribute tactile stimuli around the full perimeter of the head — the only form that can reconstruct the directionality of environmental sound. Haptic actuators positioned to correspond to real-world sound sources, creating a perceptual map that the user learns and internalises over time.
