MyVoice cause and effect games

Cause and effect is the first thing a switch teaches: I did that. These eleven activities are built for that moment and the ones just after it — a single enormous target that rewards every press, then games where the reward differs depending on which thing you press, and where what you make (or watch) stays on the screen.

Fireworks needs one button and nothing else, and Paint Splat works the same way — or paints exactly where you touch or look, so the picture is the player's own. Pop the Bubbles adds a target that moves — and can be popped by looking straight at it. Instrument Studio has eight playable instruments — piano, synth, guitar, bass, drums, xylophone, strings and bells — plus a loop recorder and an easy-song mode where any note advances the tune, so a player who cannot aim yet still makes real music. This or That is the step into choosing. Sensory Spirals is built for the moment before any of that: a glowing pattern plays against a black screen with a short song, then waits — no aiming and no timing needed, just one big press for a brand new pattern and song.

Three of them answer that question in different tenses. Bubble Wrap is a sheet where every bubble pops and then, a few seconds later, fills itself back up — so the activity has no end, nothing to clear and no moment where an adult has to reach over and reset the screen. Light Board is the step past “something happened” to “something changed”: press a bulb and it lights, press it again and it goes out, which is the first undo many of these players are ever handed. And Stardust is a black screen with no press in it at all — colour follows wherever you look, in sparks, stars, ribbons or opening blooms, and then fades back to black so the newest movement is always the brightest thing there. Each has a page of its own.

Look & Draw is the odd one out here, because it has no press at all. The line follows wherever the pointer — or the gaze — goes on the paper, so drawing stops being a drag and becomes just looking. There are colour pens on black or white paper, and a rainbow scratch card where a black coating comes away wherever you look. On a single switch the brush travels a looping path of its own and the big button decides whether it leaves a trail, so the player's contribution is the timing — and it has a page of its own.

Grid Fit asks the question that comes before a page set: how many buttons can this person hit, at what size, and where on the screen? The grid is a Whack-a-Mole board, so the player keeps playing while the answer arrives — and the mole always pops up in the button it has visited least, so a session sweeps the whole grid instead of settling in the easiest corner. It starts at 2 x 4, and the rows, columns, size, gap and position all move to match a keyguard on the glass. Full-screen fit stands the menus down so the grid can reach every edge of the display, and it has a page of its own.

Everything here works with touch, a single switch, two switches, or eye-gaze dwell. Scan speed, dwell time, target size, effect intensity and spoken praise are all in the app's Settings panel, and can be saved per player on the device.
