Abstract

The presently disclosed subject matter relates to a play environment for children and infants for detecting motor delays or impairments, evaluating neurological development, and for diagnosing developmental disorders, and methods and systems of using the same.

First claim

What is claimed is:

1 . A play environment for evaluating neurological development and diagnosing a developmental disorder in a child comprising:
a. a mat; b. one or more toys comprising an IMU sensor and a pressure sensor, wherein the one or more toys are placed in proximity to the child; and c. an imaging sensor configured for tracking the child while interacting with the one or more toys; wherein the IMU sensor, the pressure sensor, and the imaging sensor, are each communicatively coupled to a central processor, and configured to collect and send at least one type of movement data and cognitive data to the central processor, wherein said movement data comprises physical interactions including kinematic and haptic interactions, or said cognitive data comprises a variable selected from the group consisting of frequency of toy stimulus event, frequency of toy feedback event, response times, frequency of touch response, and frequency of look response, and wherein said movement and cognitive data is compared with a past dataset to identify warning signs of a developmental disorder.

2 . The play environment of claim 1 , wherein said one or more toys are adapted for collecting and measuring at least one type of movement data or cognitive data.

3 . The play environment of claim 2 , wherein said one or more toys further comprises a feedback mechanism that generates sound, vibration or light.

4 . The play environment of claim 1 , wherein said mat is embedded with one or more sensors, said one or more sensors are adapted for collecting and measuring at least one type of movement data or cognitive data.

5 . The play environment of claim 1 , further comprising a framework.

6 . The play environment of claim 5 , wherein said framework comprises a cross connection, wherein said cross connection comprises two to four flexible bars.

7 . The play environment of claim 5 , wherein said framework is collapsible.

8 . The play environment of claim 6 , wherein said framework further comprises one or more adjustable parallel bars attached to the flexible bars of the cross connection, wherein said parallel bars are detachable from the flexible bars.

9 . The play environment of claim 5 , wherein said one or more toys are attached to said framework.

10 . The play environment of claim 1 , wherein said imaging sensor comprises a motion capture imaging system.

11 . The play environment of claim 1 , wherein said imaging sensor comprises a stereo camera.

12 . The play environment of claim 1 , wherein said child is an infant.

13 . The play environment of claim 12 , wherein said child is an infant between the ages of 2 months and 11 months old.

14 . The play environment of claim 13 , wherein said mat is located on at least four load cells, wherein the at least four load cells are configured to measure ground reaction force, location of the ground reaction force, movements of the infant on the at least four load cells, or combinations thereof, wherein the ground reaction force is a sum of forces on the at least four load cells.

15 . The play environment of claim 14 , further comprising at least one camera that record and transmit actions of the child for analysis, wherein the actions are selected from the group consisting of head actions, left and right arm actions, left and right leg actions, torso actions, and a combination thereof.

16 . The play environment of claim 15 , wherein the play environment is configured to track the at least one type of movement on the mat by detecting movements of arm, body, legs, head or a combinations thereof.
