| 1 | # FT-05: On a screen |
| 2 | |
| 3 | <!-- Generated from field-tests/suite.json by tools/field_tests.py. Edit the JSON, not this file. --> |
| 4 | |
| 5 | **Category:** Screen · **Time:** about 10 minutes · **Run it and see results:** [https://openckey.org/tests/test?id=FT-05](https://openckey.org/tests/test?id=FT-05) |
| 6 | |
| 7 | ## What it checks |
| 8 | |
| 9 | A CKey shown on a phone or computer screen reads, including at low brightness and in light-on-dark colours. |
| 10 | |
| 11 | ## Why |
| 12 | |
| 13 | Many codes are read off another screen: a ticket in a wallet app, a slide, a monitor. Screens add moiré, refresh banding and glare that paper does not. |
| 14 | |
| 15 | ## Test codes |
| 16 | |
| 17 | Print or open the sheet at [https://openckey.org/tests/sheet?id=FT-05](https://openckey.org/tests/sheet?id=FT-05). It is drawn by the CKey web SDK from the values below. |
| 18 | |
| 19 | | Code | Size | Version | Level | Layout | Style | Holds | |
| 20 | |---|---|---|---|---|---|---| |
| 21 | | A | 2.0 in | smallest that fits | M | standard | plain | `https://openckey.org/t/FT05-A` | |
| 22 | | B | 2.0 in | smallest that fits | M | standard | dark | `https://openckey.org/t/FT05-B` | |
| 23 | |
| 24 | ## Set up |
| 25 | |
| 26 | 1. Open this test's sheet on a second device: another phone, a tablet or a computer. |
| 27 | 2. Make each code about 2 inches (5 cm) wide on that screen. |
| 28 | |
| 29 | ## Steps |
| 30 | |
| 31 | 1. Try code A (black on white) at full brightness, then at the lowest comfortable brightness. |
| 32 | 2. Try code B (light on dark) at full brightness. |
| 33 | 3. Try code A on a computer monitor at arm's length. |
| 34 | 4. Allow up to 5 seconds each and record whether it read. |
| 35 | |
| 36 | ## What to record |
| 37 | |
| 38 | - **Read within 5 seconds**, boolean, required. For each of: A, full brightness, A, low brightness, B, full brightness, A, monitor. |
| 39 | |
| 40 | Every report also records the device, operating system, reader and its version, and the printer or screen. |
| 41 | |
| 42 | ## How to grade it |
| 43 | |
| 44 | - **Pass:** Every case read. |
| 45 | - **Partial:** Code A at full brightness read, but another case did not. |
| 46 | - **Fail:** Code A at full brightness did not read. |
| 47 | |
| 48 | ## Report a result |
