People who can't picture anything are rewriting the science of imagination

Hacker News Discussion

📝 Discussion Summary (Click to expand)

Three prevalent themes in the discussion

  1. Absence of visual mental imagery while other cognitive modalities remain intact (or even enhanced)
  2. misthop: “She's 5 ft tall, sharp features, curly white hair. I can remember imagery facts, but have not visual memory.”

  3. vidarh: “I can describe someone from memory, and I can draw them, but I can't see them unless they're in front of me (or I'm looking at a photo).”

  4. Visual imagery can occur in dreams or altered states despite aphantasia while awake

  5. vidarh: “Except, as someone with aphantasia, I see things in my dreams, so I know that seeing things is possible with my eyes closed.”

  6. godshatter: “I can't visualize at all when awake, but I have been into lucid dreaming in my past and my dreams were visual and more detailed than real life.”

  7. Debate over whether aphantasia reflects a genuine difference in phenomenal experience or merely differences in description/ability

  8. suddenlybananas: “I think this is cope to avoid the realization that some people are walking around with drastically different life experiences.”
  9. hackinthebochs: “It's a real phenomena. Mental imagery corresponds to voluntary activation of the visual cortex … People with aphantasia have little to no visual cortex activity.”
  10. izzydata: “I think a lot of people that can 'see' in their mind are over‑estimating their ability and a lot of people who can't are under‑estimated their ability.”

🚀 Project Ideas

Aphantasia-Assist: External Visualization Aid

Summary

  • Generates sketches or diagrams from textual descriptions to compensate for lack of mental imagery.
  • Core value: turn factual descriptions into immediate visual references for faces, objects, or spatial problems.

Details

Key Value
Target Audience Aphantasic individuals, students, designers needing visual aids
Core Feature Text‑to‑sketch generation using AI (Stable Diffusion) with editable canvas
Tech Stack React frontend, Python/FastAPI backend, HuggingFace Diffusers API, WebGL for preview
Difficulty Medium
Monetization Revenue-ready: Subscription tier ($5/mo) for high‑resolution exports and private storage

Notes

  • HN users describe the frustration: “I can describe an apple to you in great detail. I cannot imagine all of those things I described in a coherent image” (misthop). This tool would give them that missing image.
  • Practical utility: solving geometry puzzles, recalling faces, or visualizing product designs without relying on inner visualization.

FaceRecall Trainer

Summary

  • Spaced‑repetition flashcard app that teaches face recognition using factual, auditory, and contextual cues instead of visual memory.
  • Core value: replace the missing visual recall with reliable associative cues for names and identities.

Details

Key Value
Target Audience Aphantasics who struggle to recognize faces after delays
Core Feature Fact‑based flashcards (e.g., “voice pitch, typical clothing, context”) with audio hints and SM‑2 scheduling
Tech Stack Flutter cross‑platform app, Firebase Firestore for decks, Firebase Auth
Difficulty Low‑Medium
Monetization Revenue-ready: Freemium model – free basic decks, premium specialized decks ($3/mo)

Notes

  • Commenters note the effort needed: “I have to scan everyone and wait for that ping of recognition to happen” (misthop). The app would automate cue training.
  • HN audience would appreciate a data‑driven approach to a common social pain point, sparking discussion on memory techniques.

Spatial Reasoning Workbench

Summary

  • Desktop tool that lets users manipulate 3D objects via natural‑language commands, enabling spatial problem‑solving without mental visualization.
  • Core value: turn descriptive reasoning into tangible on‑screen models for geometry, engineering, or design tasks.

Details

Key Value
Target Audience Engineers, students, aphantasics strong in spatial reasoning but weak at visualization
Core Feature NL‑to‑CAD interpreter (e.g., “rotate cube 45° around Y axis”) with real‑time Three.js preview
Tech Stack Electron (React + Node.js), Three.js, spaCy or LLM for command parsing
Difficulty High
Monetization Revenue-ready: Per‑seat licensing for schools/teams ($8/user/mo)

Notes

  • Users highlight spatial strengths: “I can draw what I can't see pretty well from memory” (vidarh) and “I can recall the visuals of a movie scene… spatial memory of where things are” (misthop). The workbench leverages that strength.
  • Could become a classroom aid for teaching geometry to neurodiverse learners, inviting practical utility and HN debate.

Inner Monologue Amplifier

Summary

  • Mobile app that converts a user’s inner monologue into audible speech in real time, letting aphantasics hear their thoughts externally.
  • Core value: make the internal verbal scaffold audible, improving retention and manipulation of ideas.

Details

Key Value
Target Audience Aphantasics who think primarily in inner monologue and want auditory feedback
Core Feature Speech‑to‑text (optional) + instant text‑to‑speech playback with adjustable voice/speed
Tech Stack React Native, Web Speech API (or Azure TTS), local storage for transcripts
Difficulty Low
Monetization Hobby

Notes

  • Many aphantasics describe reliance on inner voice: “I have an inner monologue that can sing… I use my inner monologue to sing or hum it in my head, I don’t hear it” (misthop). Hearing it would close that loop.
  • Simple yet valuable for studying, brainstorming, or reducing cognitive load, likely to resonate with HN’s tool‑building community.
