"Keep swinging up and down as the life does so"
Why CognoKids Playground?
Imagine trying to help your child find an object at home over the phone. You tell them, "It's on the dining table," yet they still can't find it. Understanding spatial and directional concepts such as on, under, above, between, inside, and around is an essential part of language development, but these concepts are often learned gradually through everyday sensory experiences rather than explicit instruction.
For children with visual impairments, intellectual disabilities, or other cognitive challenges, acquiring these concepts can be considerably more difficult. Limited sensory input may affect how children develop an understanding of space, direction, and object relationships, making conventional teaching methods less effective.
Inspired by years of academic research and practical experience, Dr. Tahereh Mahmoodi Ahmad Abadi developed the educational concept behind CognoKids Playground to provide a more engaging and accessible way to teach spatial concepts. Her doctoral and master's research explored how sighted and blind individuals acquire directional concepts and highlighted the unique challenges faced by children with visual impairments.
CognoKids Playground is an interactive educational device designed to transform abstract spatial concepts into tangible learning experiences. Children learn by physically manipulating specially designed objects while receiving immediate audio feedback, allowing them to associate movement with language through multisensory interaction.
The prototype features a collection of textured objects including cubes, cones, cylinders, stars, pears, and other shapes—that children move along guided pathways. Hall-effect sensors detect each interaction and trigger corresponding audio cues, reinforcing concepts such as up, down, under, over, between, inside, and many others. The platform is being designed to support more than 20 spatial and directional concepts, with the flexibility to expand as development continues.
Each object incorporates distinctive textures and shapes to encourage tactile exploration, making the learning experience particularly suitable for children with visual impairments while remaining engaging for sighted learners. Bright colors, interactive sounds, and hands-on activities create an enjoyable environment that promotes active participation and concept retention.
At Cognorehab, our mission is to develop accessible educational technologies that help children build foundational language and spatial reasoning skills through meaningful, multisensory learning experiences. We believe CognoKids Playground represents an important step toward making cognitive and language development more inclusive for children of all abilities.
How Cognokids Playground Teaches Directional and Movement Concepts
CognoKids Playground is an interactive educational device designed to help children learn spatial, directional, and movement concepts through visual, tactile, and audio experiences.
The prototype is designed to teach more than 20 spatial and movement concepts to sighted, partially sighted, and blind children. It features a base plate with four sections of guided rods, a cross-section box, a balance platform, and a push-and-pull cabin integrated with an electronic audio system.
Children interact with specially designed objects of different geometric shapes and textures by moving them along the guided rods. Hall-effect sensors detect each interaction and trigger corresponding audio feedback, reinforcing the concept being learned through multisensory engagement.
The balance platform introduces concepts related to balance and stability, while the push-and-pull cabin helps children understand actions such as pushing, pulling, opening, closing, and directional movement.
CognoKids Playground can be used in two modes:
-
Instructor-Guided Learning – Teachers, therapists, or parents guide children through structured activities.
-
Interactive Audio Learning – The built-in electronic system provides immediate spoken feedback, enabling children to learn independently while reinforcing each concept.
By combining hands-on interaction with real-time audio feedback, CognoKids Playground creates an engaging learning environment that supports language development, spatial reasoning, and cognitive growth.
Digital Sound System (DSS)
The Digital Sound System (DSS) is the interactive core of CognoKids Playground. It detects each user interaction and provides immediate audio feedback, reinforcing spatial and movement concepts as children explore the playground.
Using Hall-effect magnetic sensors integrated throughout the playground, the DSS accurately detects the position and movement of each learning object without mechanical wear. The sensors communicate with a microcontroller that continuously monitors user interactions and triggers the appropriate audio responses in real time.
The system can also transmit activity data wirelessly via Wi-Fi to a smartphone or tablet, allowing instructors to record, review, and analyze each training session. This enables educators and therapists to monitor progress, evaluate performance, and adapt learning activities to each child's needs.
"Hall Effect Sensors in Cognokids Playground"
Cognorehab Team has utilized Hall Effect Sensor technology to set up a digital sound system for the Cognokids Playground. The Hall Effect Sensor is a thin rectangular piece of semiconductor material, such as gallium arsenide or silicon, through which a small current flows. When a magnetic field is applied perpendicular to the current, the electrons in the material are deflected to one side of the conductor, resulting in a measurable voltage difference between the two sides of the conductor. By integrating Hall Effect Sensors into the digital sound system of the playground, Cognorehab is able to accurately detect the movement of the various components, such as the rods, balls, and doors, and generate corresponding audio messages for the children. This technology allows for a more interactive and engaging learning experience for children, as they can receive immediate feedback and reinforcement for their actions.
