Infrared / Thermal Vision
Perceive heat signatures and thermal gradients from any object, surface, or living being.
Use Cases
- • Firefighters navigating smoke-filled buildings
- • Security: detect warm bodies in darkness
- • Medical: perceive inflammation and circulation patterns
- • Navigation: full spatial awareness without light
How It Works
Thermal cameras detect infrared radiation. Encoding algorithms map temperature values to neural stimulation patterns. Visual cortex (or skin haptics) trains on the signal.
Current Research
David Eagleman lab: thermal haptic vests demonstrated in sighted subjects. Subjects reported genuine spatial thermal awareness after 2-3 weeks of training.
Ultraviolet Vision
Perceive UV light patterns invisible to human eyes — present in flowers, biological fluids, and material surfaces.
Use Cases
- • See pollinator patterns in plants (bees see this)
- • Detect biological fluids (forensics, medicine)
- • Identify material authenticity (UV-reactive inks)
- • New form of biological communication
How It Works
UV cameras capture 10-400nm range. Signal encoded to visual cortex via similar pipeline as infrared. The brain builds a new "color channel."
Current Research
Some aphakia patients (removed eye lenses) report partial UV sensitivity — the lens normally blocks UV. Implies visual cortex CAN process UV if signal reaches it.
Radio Signal Awareness
"Feel" the presence and intensity of WiFi networks, cellular signals, Bluetooth, and radio transmissions as spatial sensation.
Use Cases
- • Feel device density in a space
- • Navigate by signal strength gradients
- • Sense surveillance infrastructure
- • New form of environmental awareness
How It Works
Software-defined radio detects RF signals. Intensity mapped to haptic patterns on skin (wrist, fingertips). Brain learns to spatially interpret signal density.
Current Research
Cyborg artist Neil Harbisson has an antenna implant that converts colors and radio waves to bone-conducted sound. Has used this for 10+ years with full integration.
Radar / Spatial Mapping
Perceive environment three-dimensionally through obstacles — walls, smoke, water — using radar or ultrasound.
Use Cases
- • See structure and occupants through walls
- • Navigate complex 3D environments in darkness
- • Detect objects without line of sight
- • Spatial awareness independent of light conditions
How It Works
Radar or ultrasound array generates 3D point cloud data. Compressed and encoded to tactile or visual cortex. Brain builds volumetric spatial model.
Current Research
Bat echolocation demonstrated as trainable in humans via tongue clicks. Subjects navigate rooms and identify objects with eyes covered after training.
Magnetic Field Sense
Always know true magnetic north. Feel orientation and direction like migratory birds.
Use Cases
- • Intuitive navigation without maps or GPS
- • Geological and environmental sensing
- • Spatial memory enhancement (birds with this sense have extraordinary spatial recall)
- • Deep wilderness orientation
How It Works
Magnetometer detects field strength and direction. Signal encoded to fingertip or cortical stimulation. Brain learns directional meaning over 2-4 weeks.
Current Research
Multiple biohackers have implanted magnetic fingertip implants (neodymium) and report genuine magnetic field sensation. Gabriel Silva created a brain-implanted magnetoreceptive device in 2014.
Molecular / Chemical Awareness
Detect chemical compounds, biological markers, toxins, hormones, and health states at the molecular level.
Use Cases
- • Perceive air quality and toxin presence
- • Sense own hormonal states and health markers
- • Detect disease biomarkers in environment
- • Food safety and contamination sensing
How It Works
Electronic nose (e-nose) arrays or MEMS chemical sensors detect molecular signatures. Signal mapped to olfactory or haptic cortex stimulation.
Current Research
E-nose technology can already distinguish thousands of compounds. The encoding and neural integration remains unsolved. Bioelectronics firms (Biolinq, Sensirion) working on wearable molecular sensors.
Temporal Expansion
Experience time at different rates — faster perception loops for rapid decision-making, or slower subjective time for deep concentration.
Use Cases
- • Athletes making split-second decisions with more cognitive processing time
- • Surgeons with slowed subjective time for precision
- • Emergency responders processing complex situations faster
- • Enhanced contemplation and mindfulness states
How It Works
Unclear. Possible approaches: direct modulation of neural oscillation frequencies (gamma wave manipulation), targeted neuromodulation of time-perception circuits in parietal cortex.
Current Research
Adrenaline states produce natural subjective time dilation. Transcranial alternating current stimulation (tACS) can alter perception of time intervals. Direct volitional control remains experimental.
Abstract Data Perception
"Feel" abstract information — market volatility, probability distributions, system states — as intuitive sensory experience rather than visual data.
Use Cases
- • Traders sensing market momentum as haptic texture
- • Portfolio managers feeling risk as spatial weight
- • Researchers intuiting statistical patterns before analysis
- • Operators monitoring complex systems via ambient sensory awareness
How It Works
Data values mapped to tactile, auditory, or (eventually) neural signals. Brain trained to interpret data patterns as meaning. This is data sonification and haptic finance expanded.
Current Research
MIT Media Lab and Georgia Tech have built haptic data gloves for financial data. Stock price encoded as pressure/vibration — subjects report genuine market "feel" after training.
Frequently Asked Questions
What senses could humans gain through BCI?
Through brain-computer interfaces and sensory substitution, humans could gain: infrared/thermal vision, ultraviolet vision, radio signal awareness, radar/spatial mapping, magnetic field sense, molecular/chemical perception, temporal expansion, and abstract data perception (feeling stock markets, probability, etc.).
Which expanded sense would be most useful?
Infrared vision has the highest immediate practical value — detecting heat in darkness has applications in emergency response, security, medicine, and navigation. Abstract data perception may be the most commercially transformative for knowledge workers.
Do any expanded senses already work?
Yes. Non-invasive sensory substitution devices can already deliver crude thermal awareness, ultrasound spatial data, and magnetoreceptive orientation sense. These work through haptic skin interfaces, not brain implants.
