Case Study: 

Simple Gestures, Complex Combos

External Survey (n = 112) | Internal User Survey (n = 28) | Usability Interviews (n = 11) 

What was the motivation behind the product pairing push?

Executive leadership was intrigued by a proposed $300 standalone accessory pairing with an audio-only feedback experience, and needed directional answers on user interest before committing to a public Early Access release.

For users

Silent, discreet control without voice commands

For the business

A differentiated input across the competitive wearables market and a new standalone revenue line

The underlying assumptions

• Users find discreet input for their glasses a major pain point

• Users will find hand gestures via this accessory an innovative and compelling solution to this problem

• Users will be willing to buy an additional standalone wearable accessory in order to solve their discreetness pain point

Research questions

• Are users interested in a standalone release of this accessory to pair with audio-only glasses?

• Are users who already have the accessory interested in an audio-only feedback mode for display glasses?

• Can users understand, recall, and execute gestures that gate the sensing of inputs?

Mei's role

• Sole UXR, end-to-end ownership of all 3 studies

• Partnered with 7 product managers, 2 designers, 2 data scientists, 4 engineers across 3 separate teams

• Led study design, recruiting, 11 lab sessions, quant and thematic analysis, reporting, and bug escalation

• Delivered 3 reports plus a combined executive summary

The challenges

• Too many owners: 7 product managers on different teams with competing priorities. Mei defined the problem space clearly for all parties, even where no satisfying solution existed yet.

• Software not ready: Launch day software, no dry runs, and a mid-study gesture conflict bug. Mei caught unnoticed issues live, helped engineers fix them fast, and scored blocked tasks with explicit caveats.

• Competitive timing: Executives requested compressed reporting from 2 weeks to 1 to rush the early access release alongside a rumored competitor launch, with the accessory positioned as our differentiator. Mei prioritized analysis so a defensible topline was ready first.

External Survey (n = 112)

• Display glasses owners with accessory experience  (n = 54) vs audio-only glasses owners without accessory experience (n = 58)

• 2 variations of 10 - 12 question mixed quant / qual concept surveys measuring perceived value and buy/use intent (5 pt unipolar scales, target ≥ 4.0 mean with 95% CI)

• 4 sections: intro to product concept, current device usage patterns, concept evaluation, anticipated use of product concept

Reasoning behind the method

Initial decision was a go/no-go on market viability, the design questions would come later in the process. We wanted to know “how many” and “how much” for a defined population.

• Pros: Quantified demand across segments before software investment, large enough sample size for CIs and margins of error which can help leadership understand risk/reward of investment with defensible margins.

• Cons: Concept based, user stated intent can overestimate purchase behavior. Also can’t fully diagnose reasoning behind purchase intent (or lack thereof). These risks were mitigated by triangulating within lab observation and internal testing in later studies.

Additional 2 studies Mei used to triangulate results

• Internal User Survey (n = 28): Advanced internal display users, critical user journey task success recorded via 4 at home tasks measured against internal benchmarks

• Usability Interviews (n = 11): Mixed experienced and new users of wearable accessory, observed critical user journey task success and sentiment of audio-only experience in 45 - 60 min lab sessions

The input gate, not the gestures, was the bottleneck

Users understood individual gestures (4.70 ± 0.30 on understanding during interviews), but consistently forgot to open sessions, lost track of session state, and couldn't chain gestures within the 5 seconds time limit.

Without a visual via display, users lost the feedback loop

Half of interview participants couldn't tell when sessions were open, and a majority missed the session timeout signal. Quiet audio cues and no visual confirmation inflated perceived complexity of interactions.

The value gap was structural, not fixable gesture friction

34% of users activate music as their first action, but only 14% anticipated using the proposed accessory for that feature (voice already covers users’ needs at 73% activation rate). Non-owners’ purchase intent ceiling was 3.07 ± 0.35 in external surveys, before even trying the product pairing.

What was assumed

A discreet hand gesture based accessory can sell as a standalone product at ~$300, with an audio-only feedback pairing worth executive sponsorship.

What we found

Use cases were more niche than proposed, and the realistic market of a standalone product was only ~22% of audio-only glasses owners

What was decided

The standalone accessory was released to a limited, targeted market. Teams continued investment in an audio-only feedback mode for users who already owned the accessory. Leadership defocused the push for the audio-only glasses and accessory pairing as the differentiator against the competitor.

Downstream wins

• Gesture conflict bug escalated as top pre-release quality issue, fixed by engineering

• Session durations for music interactions (the most complex combinations) were increased from 5 to 10 seconds

• Audio signals for session start / end were reworked to be more distinct and recognizable

• Flagged risk for proposed ~$300 price point, follow-up studies coordinated with marketing research
