This activity has been designed to encourage exploration of the whole screen and teach basic touch and drag skills including options for single or multitouch. Drag your finger around the screen to reveal coloured shapes and patterns, with different sound effects that change pitch. When you lift your finger the tiles will fade. Black background, different sound effects and bright colours make this a very motivating activity for children with visual impairments as well as being great fun for the very young. The great feedback makes this an ideal cause and effect activity that can help develop hand eye co-ordination. Key Features: • Black background and bright colours ideal for low vision. • Single touch to encourage finger isolation and pointing - may be easier for some users to understand. • Multi-touch for maximum feedback. • Simple interaction and fun for very young children.

About

Sensory DrumKit

Features
Read full description

Drum Kit is an interactive music activity designed for children and young people of all abilities. Press the four large colourful pads to trigger drum sounds, musical motifs, or playback controls — and watch the screen come alive with animated visual effects. SIX MUSIC STYLES Choose from Big Band, Ragtime, Classical, Dance, Disco/Funk, and Jazz — each with a curated playlist of songs that loop and cycle at the press of a button. Songs range from Joplin ragtime to Mozart, Tchaikovsky, Debussy, jazz bebop, and four-on-the-floor disco. Pressing the same style button again advances to the next song in the playlist. THREE PLAYING MODES • Drums — each pad plays a different drum sound using high-quality sampled percussion (kick, snare, hi-hat, cymbal) • Motifs — each pad plays a short musical phrase tuned to the current song's key, so it always sounds musical • Control — pad 1 plays, pad 2 stops, pads 3 & 4 play kick and snare TWO VISUAL STYLES Switch between the Young (bright, playful) and Older (metallic, sophisticated) interfaces to suit any preference. Your choice is remembered between sessions. HIGH QUALITY AUDIO Background music is played using WebAudioFont — a bank of high-quality sampled instruments covering piano, strings, brass, bass, and full GM percussion. All music is stored on-device for offline playback. KEYBOARD ACCESSIBLE Full keyboard shortcuts for all four pads, play, stop, style selection, tempo, and volume — making the app accessible without touch.
