Sense²

The description states that Sense² is a browser-based prototype designed to turn a phone camera into a spoken situational awareness tool. It uses:

• A phone camera and microphone
• OpenAI Realtime API sessions
• WebRTC for real-time communication
• Motion detection across multiple frames

It is described as having three main capabilities:

1. Conversational awareness: Users can ask questions, interrupt responses, and follow up.
2. Ambient Mode: Observes quietly and speaks only when something meaningful changes.
3. Find Mode: Guides the user’s hand toward an object using spatial instructions.

The system stores a short visual history to detect movement and explain what changed over time.

Inference The product is not yet commercially available, but rather a proof-of-concept built for a hackathon.

The description states that Sense² was built around the question:

“What if visual assistance felt like a companion rather than an image-captioning tool?”

It positions itself as:

• A companion-like assistant, not just a caption generator
• Focused on spatial understanding and change detection
• Designed to help users understand where things are, what changed, and how to act

The authors claim the system avoids describing everything, instead focusing on what helps the user understand or act.

Inference This is a shift from traditional image captioning tools toward a more dynamic, interactive, and contextual form of visual assistance.

The description states that Sense² is built for blind or low-vision individuals, aiming to provide situational awareness and guidance in real-time.

It mentions:

• Users who want to understand their surroundings
• Those needing help navigating objects or environments
• People who benefit from spatial instructions like “move slightly right” or “the bottle is directly below your hand”

Inference The target customer segment is people with visual impairments, but no specific demographics (age, severity of impairment, etc.) are provided.

There is no evidence in the description of:

• A pricing model
• Revenue streams
• Monetization strategy
• Customer acquisition plans

The project is described as a prototype, not a commercial product.

Inference No business model or pricing data are evident from this self-reported write-up.

The description states that the system:

• Is built in a TypeScript pnpm monorepo
• Uses WebRTC for real-time camera/microphone/audio communication
• Relies on OpenAI APIs, including Realtime API
• Separates logic between browser (sensor) and server (intelligence)
• Stores short visual history to detect motion and explain changes
• Implements multi-frame understanding to interpret actions like waving or entering a room

It also mentions:

• Motion score diagnostics
• Frame selection algorithms
• Stale-result rejection mechanisms
• Timestamped responses

Inference The architecture supports scalability across devices (phone, glasses, wearables), but no delivery or deployment details beyond prototype development are given.

There is no evidence of:

• Revenue
• Customers
• Product adoption
• Market traction
• Commercial use cases

The project is explicitly described as a hackathon submission, and the authors state they are testing it with blind/low-vision users in future steps.

Inference No maturity or traction signals are evident beyond the prototype stage.

There is no mention of:

• Competitors
• Existing solutions in the market
• Market size or competitive landscape

The description does not reference other assistive technologies, AI vision tools, or accessibility products.

Inference No competitive context is provided; this may be a new or niche space with limited known players.

Key risks and red flags based on the self-reported description:

1. No commercial traction or revenue evidence: The project is described as a prototype, not a product.
2. Unverified user testing claims: No data or feedback from blind/low-vision users beyond author statements.
3. No pricing or monetization strategy: Unclear how this will be monetized if launched.
4. Limited technical detail on scalability: While architecture is described, no evidence of performance at scale.
5. Dependency on OpenAI APIs: Reliance on external services introduces risk and cost uncertainty.

Inference The project lacks commercial viability indicators and user validation.

1. Have you conducted any usability testing with blind or low-vision users?
2. What is your plan for monetization or revenue generation?
3. How do you intend to scale beyond the current prototype?
4. Are there any technical limitations in real-world deployment (e.g., latency, bandwidth)?
5. What are the key assumptions about user behavior and needs that drive this product design?
6. Do you have access to funding or partnerships to support further development?

evidenced

The description states: "Most visual-assistance tools work like cameras: take a photo, wait, hear a description, and repeat."

It also says: "For a blind or low-vision person, understanding these changes can be more useful than hearing a detailed description of one image."

Inferred

The project is built for users who are blind or have low vision, based on the stated goal of providing situational awareness to those with visual impairments.

evidenced

The description states: "Sense² turns a phone camera into spoken situational awareness."

It also says: "Instead of saying: 'There is a cup on a table.' Sense² aims to say: 'A cup is slightly to your right, about an arm’s length away.'"

Additionally: "The goal is not just to describe the scene. It is to help the user understand where things are, what changed, and what they can do next."

Inferred

The value proposition includes conversational awareness, ambient mode for change detection, and find mode for object guidance — all aimed at improving situational understanding for blind or low-vision users.

evidenced

The description states: "Sense² is a TypeScript pnpm monorepo with a clear separation between the browser and the product intelligence."

It also says: "We use WebRTC for realtime camera, microphone, and audio communication."

Inferred

The application is intended to be used via a phone, as it's described as being built around three main capabilities that are meant to work on a mobile device.

evidenced

The description states: "Users can ask questions naturally. The application streams camera and microphone input to an OpenAI Realtime session and responds through spoken audio."

It also says: "Users can ask follow-up questions without starting over."

Additionally: "Interrupt the model" is possible, indicating a dynamic interaction.

Inferred

The relationship involves real-time interaction with users who are blind or low-vision, allowing for natural conversation and interruption of responses.

There is no mention in the description of how revenue would be generated from this product. No pricing model, monetization strategy, or business model details are provided.

evidenced

The description states: "Sense² is a TypeScript pnpm monorepo with a clear separation between the browser and the product intelligence."

It also says: "We use WebRTC for realtime camera, microphone, and audio communication. The OpenAI API key and product instructions always remain on the server."

Additionally: "The browser acts as a lightweight sensor. It captures the camera and microphone, plays audio, maintains a small frame buffer, and calculates basic motion signals."

Inferred

Key resources include access to OpenAI APIs, WebRTC infrastructure, and software development tools like TypeScript, Next.js, React, and pnpm.

evidenced

The description states: "Sense² is being developed around three main capabilities: Conversational awareness, Ambient Mode, Find Mode."

It also says: "We built a working browser-based voice and vision prototype where users can start a camera and microphone session, ask questions naturally, hear spoken responses, interrupt the model, ask contextual follow-up questions, analyse changes across multiple frames."

Additionally: "We built diagnostics for motion scores, frame selection, pending requests, stale responses, and narration decisions."

Inferred

Key activities involve developing conversational interfaces, implementing change detection algorithms, creating object identification systems, and testing with target users.

evidenced

The description states: "We use WebRTC for realtime camera, microphone, and audio communication."
