ThumbsUp buying guide
How should you set up gesture-based customer feedback?
ThumbsUp uses the selfie or front-facing camera on a compatible Android tablet to recognize a supported hand or thumb gesture and turn it into a feedback result. This guide explains how to write one clear question, place the tablet where a person can respond safely, and test the interaction for the real site rather than treating gesture recognition as a universal guarantee.
For Customer-experience, operations, accessibility, or service-design lead responsible for a physical feedback point.
Decision frame
Start with one physical service moment.
ThumbsUp helps an authorized team review a configured location and time signal. The setup still needs a site test for distance, lighting, reach, accessibility, privacy, and safe use.
Ask the question that matters to your team
Authorized managers can create or change the short question shown on assigned feedback devices. After Question Mode is enabled on those devices, customers answer the active question with a supported hand gesture—for example, “How good was the cleaning service?”—so each location can collect a signal about the service moment it wants to improve.
Start with the service moment, not the technology
A useful gesture prompt begins with the decision a team needs to make. Authorized managers can create or change a short question in Daily Questions and choose the question shown on assigned devices. After Question Mode is enabled on those devices, ThumbsUp can show an overall experience prompt or a configured custom question on the customer-facing tablet. Choose one completed service moment or defined area, then give the result a named owner who can review it.
One short gesture produces one feedback result. A compound question about speed, cleanliness, staff helpfulness, and value makes a later action ambiguous. Keep detailed reasons, account questions, and longer conversations in the channel designed to handle them instead of turning the public prompt into a typed survey.
- Name the moment or area the customer has just completed.
- Choose the operational owner who will review a meaningful pattern.
- Use an overall prompt for a broad visit signal or a custom question for one specific decision.
- Keep the device or location label aligned with the physical point being measured.
| Moment to measure | Illustrative prompt | Follow-up owner |
|---|---|---|
| Completed service visit | How was your visit today? | Site operations |
| Help or service interaction | How easy was it to get help today? | Service-point manager |
| Exit from a defined area | How was this area for your visit? | Facilities or area lead |
| Completed handoff or collection | How was the handoff today? | Handoff or fulfilment team |
Write an instruction a first-time customer can follow
The customer faces the tablet's selfie or front-facing camera and holds a supported hand gesture until the application accepts the answer and shows confirmation. The visible prompt should make both parts obvious: what experience is being rated and what simple action gives the answer. Customers do not need a personal device, app download, account, QR scan, typed response, or screen touch.
Use ordinary language and one action at a time. If the installation uses a local sign or an attendant's explanation, keep those words consistent with the question on the tablet. Tell customers to respond until confirmation rather than promising a universal response time; the configured hold and recognition settings still need to match the tested installation.
- Put the service moment in the question instead of saying only “Rate us.”
- Use a short instruction such as “Show a supported hand gesture to answer this question.”
- Avoid a compound question, technical detection terms, or a request to touch the public device.
- Use wording, text size, contrast, and language that suit the people using that service point.
- Make the confirmation visible enough that a customer knows the answer was accepted.
Make accessibility and choice part of the setup
Touchless interaction removes a screen-touch step, but touchless does not automatically make one placement suitable for every person. Test the view, reach, posture, hand visibility, lighting, text legibility, and surrounding circulation with the people who use the actual location. Do not describe one mounting height or camera angle as universally accessible without local evidence.
A gesture should be an available choice, not a barrier to service. Keep the site's existing staff-assisted or alternate feedback route available for someone who cannot, does not want to, or cannot safely stop to use the camera interaction. That route should not require a customer to disclose an accessibility need or explain why the gesture was not used.
- Leave enough space for a person using a mobility aid to approach, turn, and respond without blocking an accessible route.
- Check that the intended customer position can see the question and place a hand in the camera view without an awkward reach.
- Test the prompt and gesture with different heights, postures, hand positions, and normal lighting conditions.
- Keep staff guidance and an alternate feedback path ready when the camera interaction is not appropriate.
- Pause or move the point when the queue, doorway, safety zone, or service handoff makes stopping impractical.
| Condition | What to check | Responsible decision |
|---|---|---|
| Reach and posture | Can the intended customer respond without leaning, stretching, or entering a vehicle or moving lane? | Change the height or position, or use an alternate route. |
| View and legibility | Can the customer read the prompt and see the camera area from the real approach? | Revise the prompt or placement before expanding the pilot. |
| Hand visibility | Is the supported gesture visible at the tested distance and angle for the people using the point? | Reposition, test again, or offer another feedback method. |
| Choice and flow | Can a person decline or use another route without blocking a queue or accessible circulation? | Keep the interaction optional and protect the alternate path. |
Place and test the camera for a deliberate, stationary response
ThumbsUp runs on a compatible Android tablet with an integrated selfie or front-facing camera, reliable internet, dependable power for fixed use, and a stable mount appropriate to the environment. A tablet whose front camera is centered at the top when mounted vertically is highly recommended, but the physical installation still determines whether the customer can see and answer naturally.
Choose a position after the defined service moment, where a person can stop without steering, walking into a restricted area, closing a queue gap, or blocking staff and accessible movement. Gesture-recognition performance can be influenced by lighting, camera obstruction, viewing angle, interaction distance, incomplete hand visibility, tablet performance, and network or service availability. Test those conditions at the real point instead of generalizing from an empty room or a single successful demonstration.
- Use a secure stand, wall mount, or kiosk mount that matches the site and keeps the camera unobstructed.
- Match ThumbsUp's portrait or landscape configuration to the physical tablet orientation.
- Test direct light, shade, reflections, normal customer distance, and the actual background behind the gesture.
- Confirm that power, internet, the running application, and an active screen support the planned operating period.
- Do not describe a through-window, through-windshield, moving-vehicle, or every-site deployment as supported without a test of that exact condition.
| Test area | Record at the real location | Pass question |
|---|---|---|
| Distance and angle | Customer position, camera height, angle, and available hand position | Can a person face the camera and respond without an awkward movement? |
| Light and obstruction | Sun, shade, reflections, background, coverings, and nearby objects | Is the prompt and hand view usable during the planned operating periods? |
| Orientation and mounting | Portrait or landscape setup, camera position, stability, and cleaning access | Does the displayed view match the physical installation and stay secure? |
| Flow and safety | Queue spacing, stopping point, doorway, staff movement, and accessible circulation | Can customers respond without creating a new service or safety problem? |
Adjust documented interaction settings only after testing
ThumbsUp exposes interaction settings that can help an owner match the application to a tested installation. Use them to respond to an observed problem, not to claim a faster or more accurate result in every environment. A longer hold requirement can ask customers to keep the gesture longer, and tolerance settings affect detection behavior rather than the feedback score itself.
Keep a simple test record with the prompt, device or location, physical orientation, conditions, and settings used. Recheck the whole interaction after a change: the camera view, customer instruction, acceptance, confirmation, and the time available in the service flow.
| Setting | What it affects | Responsible use |
|---|---|---|
| Time to Hold Hand | How long the gesture must be held before feedback is accepted | Adjust only when observed interaction speed requires it; a longer value asks customers to hold longer. |
| Hand Guessing Time | Brief recovery through a missed or blurred detection frame | Change only after testing shows fast movement causes interrupted detection. |
| Maximum Deviation Score | How much hand angle can change before the hold timer restarts | Use deployment evidence; this is a detection tolerance, not a feedback score threshold. |
| Horizontal Tablet Placement | Whether the application and camera layout match landscape mounting | Match the physical orientation and verify with a real gesture after changing it. |
Interpret the resulting signal with operational context
After a response is accepted, authorized managers can review the resulting feedback through the connected dashboard with timestamp, device, and location context. Depending on the account configuration, teams can also use custom questions, employee or shift context, and other dashboard views to compare a defined service moment. Keep the question, device label, and physical placement stable enough that a change has an interpretable comparison.
A low result is a reason to investigate, not proof that a customer misunderstood the gesture, that one employee caused the experience, or that one operational factor is responsible. First check the prompt and camera conditions, then inspect the queue, service record, staffing, facilities, or other evidence owned by the local team. Ordinary feedback records contain the resulting answer or score and operational metadata; the documented vote record does not include a camera image or video.
Illustrative example: a service counter sees lower results during one busy period. The team first verifies that the prompt remained visible and the feedback point was not obstructed, then reviews the queue and handoff conditions for that period. The gesture signal helps choose what to inspect; it does not diagnose the cause by itself.
- Compare like-for-like prompts, locations, and time periods before treating a change as a pattern.
- Record prompt, placement, orientation, and setting changes so later results are not compared as if nothing changed.
- Use the result to select operational evidence and an owner for follow-up.
- Keep the alternate feedback route available for customers who need a longer explanation or a different interaction.
Questions operators ask
How should you set up gesture-based customer feedback? questions, answered clearly.
Does gesture-based feedback require customers to touch a screen?
No. ThumbsUp is designed for a customer to show a supported hand or thumb gesture toward a compatible camera-equipped Android tablet. A customer does not need to touch the public screen, scan a QR code, install an app, create an account, type, or use a personal device.
What should a gesture feedback prompt say?
Name one service moment and one action. Illustrative prompts include “How was your visit today?” after a completed visit or “How easy was it to get help today?” after a help interaction. Use the question and local instruction that match the configured device and tested customer flow.
Can the gesture be the only feedback option?
It should not be the only practical route when a person cannot, does not want to, or cannot safely stop to use the camera interaction. Keep the site's staff-assisted or alternate feedback method available and do not require a customer to explain why it was used.
Will any Android tablet work for every gesture feedback installation?
No. The installation needs a compatible Android tablet with a suitable selfie or front-facing camera, stable mounting, power, and connectivity. Test the actual distance, viewing angle, lighting, obstruction, hand visibility, orientation, and customer flow at the intended location.
How can managers change the question customers answer?
Authorized managers can create or edit short questions in Daily Questions, arrange them in a rotation, and choose the question shown on assigned devices. After Question Mode is enabled on those devices, customers answer the active question with a supported hand gesture—for example, “How good was the cleaning service?” Question scheduling and device coverage depend on the account configuration.
How can managers use a change in feedback?
Use the result, configured question, device, location, and time context to choose a focused service review. Check the interaction conditions and relevant operational evidence, make a targeted improvement, and compare the same question and service moment again.
