GazeTo โ A guide for everyone who learns and communicates with their eyes
Welcome! GazeTo is a learning and communication platform for eye gaze โ developed as part of the AssistUK project, especially for people who use or are learning Augmentative and Alternative Communication (AAC).
You need no prior experience and no special hardware. GazeTo runs in the browser and works with eye gaze just as well as with a mouse or touch.
๐๏ธ Eye gaze ยท Mouse ยท Touch โ everything works.
Whether you steer with your eyes (with any eye-gaze system), click with a mouse,
use a trackball or tap the screen with your finger โ GazeTo responds to each of
these input methods without you having to switch anything.

๐๏ธ 1. What is GazeTo?
GazeTo helps you learn eye-gaze control step by step โ from the very first look to confident communication with symbols. It offers more than 180 activities that are fun and at the same time build important gaze skills.
GazeTo is aimed at two groups at once:
- ๐ง the practising person โ they play, explore and communicate with their gaze.
- ๐งโโ๏ธ the support person (therapist, teacher, family member) โ they choose
activities, assess the current stage and follow the progress.

๐ 2. Who is practising today? โ Profiles
When you first start, you create a profile. Each profile stores its own progress, preferred settings and age group.
How to create a profile:
- ๐ Tap "New profile".
- Enter a name and choose an avatar or a colour.
- Choose the age group (child, teenager, adult, senior) โ it steers which
activities are suggested.

Tip: You can switch the profile at any time via the profile icon at the top right.
๐ฏ 3. How do I control it?
GazeTo is built from the ground up so that three input worlds work equally well:
| Input | How it works |
|---|---|
| ๐๏ธ Eye gaze (any manufacturer) | You look at a target โ a ring or circle begins to shrink. When it is full, the target is triggered. This is called dwell. |
| ๐ฑ๏ธ Mouse (or trackball, joystick) | Clicking triggers buttons. Moving over the canvas paints/responds automatically. |
| ๐ Touch (tablet, touchscreen) | Tapping = triggering. Works everywhere, with no extra settings. |
The clever part: There is no need to switch between modes. Someone who picks a target with their eyes and then continues with a trackball โ no problem.

๐ง 4. Eye gaze โ set it up once
โ ๏ธ IMPORTANT for eye-gaze users:
GazeTo makes the clicks itself through the dwell system. Your eye-gaze device
โ from any manufacturer โ should ONLY move the mouse pointer โ it should not
generate its own clicks and not trigger hardware dwell.
How to set it up:
- Open the Settings (gear icon at the bottom).
- Set the input method to "Mouse pointer / eye gaze".
- Set the dwell time โ how long you have to look until something triggers.
To begin with, 500โ800 ms is often good; for a very imprecise gaze, longer.
- Choose the size and colour of the gaze cursor so it is clearly visible.

Tip: Make sure your eye-gaze device is well calibrated and the seating distance to the screen is right. This noticeably improves accuracy.
๐ช 5. The level model
GazeTo organises all activities into 7 competence levels โ they build on each other:
| Level | Name | What it is about |
|---|---|---|
| 1 | Discover | Responding to stimuli โ noticing colour, movement, sound. |
| 2 | Explore | Cause & effect โ "my gaze makes something happen". |
| 3 | Find | Looking deliberately โ hitting a specific target. |
| 4 | Choose | Making a choice โ deciding between options. |
| 5 | Control | Steering games and sequences yourself. |
| 6 | Apply | Using what you have learned in everyday life and communication. |
| 7 | Master | Communicating confidently, independently and combining symbols. |

Each level has its own colour, which runs through the whole app.
๐ฎ 6. Finding and starting activities
Via "Activities" (in the navigation at the bottom) you find all exercises.
How to filter:
- ๐ฅ Choose an audience (All, Child, Teenager, Adult, Senior).
- ๐ช Choose a level (1โ7) โ or "All" for the full list.
- The selected level filter stays until you choose a new one.

Tap an activity to open the detail page. There you can set difficulty (Easy/Standard), play duration and more options before starting.
โถ๏ธ 7. An activity from A to Z
- Choose an activity โ the detail page opens.
- Optionally adjust difficulty and duration. "Adjust" reveals more options
(e.g. instrument, background music, background image).
- Tap "Start" โ the activity opens in full screen.
- Play with gaze, mouse or touch. A pause button is always reachable.
- When the duration ends, the review appears with stars and a gaze-path overview.

Tip for professionals: On the detail page there is a "For professionals" section with the activity's classification in the frameworks (Leber, DAGG-3, Eye Gaze Pathway) and observation tips.
โจ 8. My Area
"My Area" is the curated selection for the practising person. Activities that the support person marks with the star in the list appear here โ so the practising person can easily move through a prepared selection on their own.

๐ฉบ 9. Assessment โ the eye-gaze evaluation
For professionals and therapists there is a guided assessment that places the current development stage and recommends matching levels + intervention approaches.
How it works:
- Open Progress โ "Start assessment assistant" (or the "For professionals"
section on an activity detail page).
- Answer 6 short questions about observable behaviour (about 5 minutes).
- You receive a recommended entry level, the classification in the frameworks
and concrete intervention approaches.

The assessment is based on recognised frameworks (Tobii Dynavox DAGG-3, Irene Leber, Eye Gaze Pathway). It is an orientation tool and does not replace a formal diagnostic evaluation.
๐ 10. Progress โ the intervention cycle
The Progress screen shows the history and follows the intervention cycle: Assessment โ Plan โ Intervention โ Re-assessment.
Here you find:
- session count, practice days and streaks ("days in a row")
- a gaze evaluation (screen coverage, fixations, side distribution)
- recommended next steps and a weekly plan
- the focus areas that steer the recommendations on the start screen

๐ผ๏ธ 11. Visual scenes โ in SceneTalk
Your own talking pictures live in the sister app SceneTalk. There you pick a favourite photo, mark spots in the picture (mum, the pet, the favourite toy) and add text or a voice recording. Looking at a spot speaks the word.
SceneTalk is free and needs no account โ it runs in the browser at scenetalk.assistuk-apps.net
Three ways to get there from GazeTo:
- the „Visual scenes live in SceneTalk“ card at the top of the Activities page,
- the level hint „Your own content for this level“ on levels 2 to 7,
- the „Use in SceneTalk“ button at the end of the grid accuracy test โ the measured result fits straight into the grid you create there.
Scenes stay in SceneTalk and are backed up there. GazeTo still ships its own ready-made scene activities โ you will find them in the normal activity list.
โ๏ธ 12. Adjusting settings
In the Settings (gear at the bottom) you can adjust, among other things:
- input method and dwell time (see chapter 4)
- the gaze cursor (style, size, colour)
- volume, sounds and background music
- contrast and font size (also any time in the top bar)
- switch or edit the profile

๐ 13. Switching language
At the top right in the bar you find the language icon (e.g. "DE"). Tap it to choose from all available languages โ with flag and language name.

The whole app switches immediately. Content that is not yet translated in a language is shown automatically in English โ so everything always stays readable.
๐ฒ 14. Installing GazeTo and using it offline
GazeTo can be installed like an app and then works offline.
- On tablet/phone: Choose "Add to home screen" in the browser menu.
- On a computer: Click the install icon in the address bar โ or confirm the
"Install GazeTo" prompt.

After the first installation, GazeTo runs fully without internet โ ideal for therapy and school.
๐ 15. Privacy
GazeTo stores no personal data on servers. Profiles, progress and scene displays stay exclusively in the browser of the device (locally). There is no cloud transfer and no tracking.
๐ฅ Eye gaze runs purely locally โ no video is recorded or transmitted.
