Method and limits." url: https://gotrackgo.com/en/screen-reaction-time-measured language: en updated: 2026-11-08 publisher: GOTONOM Yazılım Teknolojileri A.Ş. --- # From product decision to screen acknowledgement: GoTrack reaction time How long does the screen take to show a product once GoTrack has recognised it in a shopper's hand? We timed every fire of a test session and publish the numbers with their method and their limits. ## The short answer **Once GoTrack has decided which product is in a shopper's hand, the screen acknowledges painting it in about a third of a second:** a median of 0.35 s with one product on the screen and 0.51 s when two products share it. The slowest of the 24 measured fires took 0.71 s. - **0.35 s**: Decision to screen acknowledgement, median with one product - **0.51 s**: Decision to screen acknowledgement, median with two products - **0.71 s**: The slowest of 24 acknowledged fires 30 September 2026, GoTrack's test setup. Method below. ## The numbers | Situation | Median | Range | Fires | |---|---|---|---| | One product on the screen | 0.35 s | 0.31–0.52 s | 11 | | Two products sharing the screen | 0.51 s | 0.47–0.71 s | 13 | | All measured fires | 0.49 s | 0.31–0.71 s | 24 | ## How we measured - **Where:** GoTrack's test setup: one screen, one store device, 8 garments. - **When:** 30 September 2026, 11:26–13:32 (İstanbul time), 25 fires. - **What was timed:** from the moment GoTrack decided which product was in hand until the screen reported that the product content was painted, on the store device's clock, including that report's trip back. - **What counted:** 24 of the 25 fires reported their render. One fire with two products on the screen did not report; it is left out, not estimated. ## What we learned **A second product costs about 0.15 s.** When a shopper picks up a second product, the screen builds a two-product layout instead of swapping one picture, and that is where the extra time goes. **The report's trip back is inside every number,** so the moment the content reaches the glass is, if anything, a little earlier than these figures. ## What is not included, and what comes next - **The time from lifting a product to GoTrack recognising it is not in these numbers.** GoTrack now records when a product is first seen in a hand and logs first-seen to screen on every fire; we will publish that measurement here, with its date. - **One day in a test setup is not a benchmark.** We will repeat the measurement in stores and add each run to the [lab notes](https://gotrackgo.com/en/lab). ## Questions ### How quickly does the screen change when a product is picked up? In our test measurement on 30 September 2026, the screen acknowledged painting the product within 0.71 s of GoTrack deciding which product was in hand, in all 24 acknowledged fires: a median of 0.35 s with one product and 0.51 s with two. One of the 25 fires sent no acknowledgement. The time from the lift itself to that decision is not included and not yet measured separately. Method: [the reaction time note](https://gotrackgo.com/en/screen-reaction-time-measured). ### Can GoTrack do lift and learn without sensors? Yes. When a shopper picks up a product, the screen beside it shows that product's content. GoTrack uses cameras, so there are no sensors, tags or pads on the products, and no touchscreen is needed. ### How do GoTrack screens decide what to show? When a shopper holds a product, the screen linked to that area shows that product's content, and keeps showing it while the product is held. When no one is holding anything, the screen plays its playlist. The screens do not need to be touchscreens. ## Further reading - [Reliability note: every fire reached the screen](https://gotrackgo.com/en/reliability-note): Lab note, 30 Sep 2026: 25 of 25 fires reached the screen, 24 reported their render, and 30 sightings of clothes being worn stayed off the screen. - [Lab note: GoTrack with the internet cable pulled](https://gotrackgo.com/en/offline-test): Lab note, 4 Sep 2026: store device offline for 7 min 43 s.
