AI Smart Glasses &
Social Sentiment

A multi-platform computational study comparing public discourse on AI wearables across Instagram, Reddit, and academic literature — examining how privacy concerns surface across 100k+ data points.

01 — Project Overview

The Research Question

Smart glasses have re-emerged after the Google Glass era with far greater commercial success — yet the core privacy tensions remain. This project asked: how are people actually talking about AI smart glasses privacy concerns, and are those conversations reaching the institutions best positioned to act on them?

We analysed Instagram Reels comments, Reddit posts, and peer-reviewed academic literature using a computational mixed-methods approach, then compared findings across all three to surface gaps between public concern, platform discourse, and scholarly attention.

Step 01 — Problem Scoping
Defining Research Objectives & Scope

As the project's de-facto business analyst and project manager, I facilitated early team workshops to align on what we were actually trying to answer.

  • Identified three key audiences: general consumers (Instagram), engaged communities (Reddit), and researchers (academic literature)
  • Translated the broad question into measurable hypotheses around sentiment proportions, temporal trends, and cross-platform gaps
  • Defined success metrics upfront: sentiment distribution, privacy-mention rates, engagement correlations, and a cross-platform comparison framework
  • Assigned team ownership: I oversaw Instagram analysis and academic literature; teammates led Reddit scraping and model evaluation

Step 02 — Literature Review
Contextualising the Research Landscape

Before touching any data, I led a structured review of prior work on smart glasses, sentiment analysis methodologies, and platform audience research.

  • Identified key prior studies including Malacko & Podhradsky (2025), Gallardo et al. (2023), and Kaviani et al. (2024)
  • Found that no prior study combined multi-platform large-scale sentiment with academic literature comparison — this became our central differentiator
  • Chose Lampropoulos et al. (2022) 17M-tweet sentiment study as the methodological precedent for VADER application
  • Documented platform structure differences to frame interpretation guardrails

Step 03 — Data Collection
Building Three Independent Data Pipelines

Each platform required a distinct scraping strategy. I coordinated all three parallel tracks and enforced quality standards throughout.

  • Instagram: Python Playwright scraper on #metaglasses and #wearabletech — 1,020 comments from 51 vetted Reels; cleaned to 671 after deduplication and Google Translate preprocessing
  • Reddit: requests + BeautifulSoup across 9 targeted and 10 general subreddits — 6,393 posts across 624 subreddits with 94,170 comments (2011–2026)
  • Academic literature: Semantic Scholar API across 5 query terms — 1,287 papers refined to 336 privacy-relevant papers via DistilBERT and manual review
  • Created and enforced a data quality checklist covering deduplication, character thresholds, relevance validation, and sampling protocols

Step 04 — NLP Modelling
Selecting & Tuning Sentiment Models per Platform

A key decision was using different models per platform rather than a single universal classifier.

  • Instagram → VADER: rule-based, ideal for short informal text; extended with a custom domain vocabulary; thresholds tuned to reduce false neutrals
  • Reddit → RoBERTa: fine-tuned on social media data; handles informal long-form text, irony, and nuanced negativity better than VADER
  • Academic literature → DistilBERT + DistilRoBERTa: efficient transformer variants for long documents; complemented by spaCy NER and BERTopic
  • All automated outputs were subject to a mandatory manual review — personally validated 300+ comments to check classification accuracy

Step 05 — Thematic Classification
Mapping Privacy Concerns & Purchase Intent

I designed and maintained the thematic classification layer using regex-based keyword maps to capture what was actually being discussed.

  • Built privacy concern taxonomy covering consent, surveillance, covert recording, facial recognition, data sharing, and bystander rights
  • Built purchase intent lexicon tracking deal-seeking and purchasing language
  • Defined 8 academic privacy subcategories mapped to BERTopic-generated keyword sets, manually validated
  • Identified product and brand mentions for cross-brand sentiment comparison

Step 06 — Analysis & Synthesis
Cross-Platform Comparison & Insight Generation

I led the analytical synthesis phase — identifying patterns that no single platform's data could reveal on its own.

  • Normalised all data to proportions rather than raw counts to account for different dataset sizes
  • Correlated sentiment with likes (Instagram) and upvote and comment counts (Reddit) to surface the "silent majority" signal
  • Tracked sentiment and privacy-mention proportions over time to identify post-scandal indifference (Meta exposé, February 2026)
  • Formally compared all three sources on sentiment distribution, privacy concern rates, and critical framing

Step 07 — Reporting & Ethics
Communicating Findings & Policy Implications

Distilled the research into a coherent academic narrative and authored an ethical analysis appendix beyond the original brief.

  • Authored the introduction, methodology, results synthesis, cross-platform comparison, and conclusion
  • Wrote an independent ethical analysis applying Rawlsian justice, social contract theory, and ACM ethical guidelines
  • Framed recommendations for platform companies, governments, and academia
  • Ensured all figures, charts, and appendices were cross-referenced and accessible to non-specialist readers

03 — Key Findings

What the Data Revealed

Select a platform to explore the findings. Each tells a different story about how privacy concern surfaces — or gets buried.

51.8%
Positive comments — overwhelmingly enthusiastic consumer reception
40.3%
Neutral comments — informational or reaction-based
7.9%
Negative comments — yet these drove significantly higher median likes
8%
Privacy-mention rate — near-static across 3 years of growing adoption

Instagram comments were dominated by hype language. Top terms included love, amazing, fire, funny, and great. Buyer intent rose steadily from 2023–2026, framing the glasses increasingly as a fashion purchase.

Key Insight: Even after a February 2026 exposé revealing Meta glasses had been covertly recording users, there was no measurable change in sentiment or privacy-mention rates. This suggests a privacy indifference pattern on algorithm-curated consumer platforms — concern spikes briefly, then subsides, and buying intent continues upward.

28%
Positive posts — significantly lower than Instagram's consumer audience
26.6%
Negative comments — up from ~20% in the early 2010s
94k+
Comments across 624 subreddits spanning 2011–2026
6%
Purchase intent — low and static, unlike Instagram's rising signal

Reddit showed a bifurcated landscape: enthusiast communities like r/RaybanMeta were net positive, while r/privacy and r/law were overwhelmingly negative. Negative proportion rose from ~20% in 2013 to over 28% in 2025 — skepticism grew alongside adoption.

Key Insight: Negative posts generated the highest median comment counts — privacy concerns, while a minority of posts, sparked the most sustained discussion. Reddit's community structure creates the impression of a divided public; in reality it is non-communicating groups talking within their own priors.

336
Papers addressed privacy-relevant topics — out of 1,287 initially retrieved
72%
Neutral papers — descriptive, technical, no clear ethical stance
68
Papers taking a Positive stance on AR glasses and societal benefit
26
Papers taking a clearly Negative stance on privacy implications

The dominant academic concern was biometric surveillance — facial recognition, gaze tracking, iris scanning. Broader social harms like bystander discomfort and normalisation of ambient surveillance were far less represented.

Unexpected Finding: The most surprising result was how muted the academic response was. For a technology with clear, documented privacy harms, only 26 of 336 relevant papers took a clearly critical stance — showing the assumption of institutional rigour is not automatic.

Placing all three sources side-by-side reveals a consistent pattern: privacy concern exists across all three spaces, but never reaches critical mass in any of them. Instagram buries it in consumer enthusiasm. Reddit concentrates it in echo chambers. Academia describes rather than challenges it.

8%
Instagram privacy mention rate — unchanged despite 3 years of growth
28%
Reddit negative proportion — growing, but siloed in privacy communities
7.7%
Academic papers with a clearly negative privacy stance (26 of 336)
Signal
Negative content drove higher engagement on both platforms — a silent majority indicator

Synthesis: The data shows that the spaces best positioned to push back are either too siloed or too neutral to create the broad pressure needed for change. The fact that negative content drives disproportionate engagement on both platforms hints at a population that recognises the concern but does not feel it is appropriate to voice in consumer-coded spaces.

Key Takeaways

Mixed methods outperforms single-model approaches

The strength came from combining automated pipelines with mandatory manual validation at every stage — a lesson directly applicable to product research and user testing design.

Platform architecture shapes the discourse you see

Instagram's algorithm and Reddit's community structure shape which concerns become visible and which never travel between spaces. Designing for feedback and privacy disclosure must account for these structural realities.

Engagement metrics can surface hidden user concerns

When negative content drives disproportionate engagement despite being a minority, the raw sentiment distribution may underrepresent actual user concern — a key insight for any UX researcher interpreting social data.

The most impactful finding was one we did not anticipate

Academia proved as muted as the social platforms — showing that assumptions of institutional rigour are not automatic, and that meaningful research questions often emerge from looking where others aren't.
