Abstract

A learning management system and method. Controllable devices, generally intended for students of a smart classroom, are each operable in a locked configuration and in an unlocked configuration. A controller device, generally intended for a teacher of a smart classroom, is configured to send command signals over a communication network. A server system interprets and handles communications between the controllable devices and the controller device such that when a locking signal is sent from the teacher's controller device, the server system sets each of the controllable devices to the locked configuration in which the user interface of each controllable device is controlled by the controller device, and when an unlocking signal is received from the teacher's controller device, the server system sets each of the controllable devices from the locked configuration to the unlocked configuration in which the user interface is operable independently of the controller device.

Claims20

Dependent claims

A learning management system using Representational State Transfer (REST), the system comprising:

controllable devices, each having a user interface, a processor for processing input commands received at the user interface, and a communication port for communicating via a communication network, each of the controllable devices being configured to selectively operate in a locked configuration and in an unlocked configuration;
a controller device having a communication port for sending locking and unlocking command signals via the communication network;
and
a server system for interpreting and handling communications between the controllable devices and the controller device, in order to:
receive the locking command signal from the controller device, and send in response thereto, a corresponding locking control signal to operate each of the controllable devices simultaneously in said locked configuration wherein the user interface of each of the controllable devices is controlled by the controller device while permitting user control at each of the controllable devices, wherein the permitting user control at the controllable device comprise permitting scrolling within restricted learning content;
and
receive the unlocking command signal from the controller device, and send in response thereto, a corresponding unlocking control signal to operate each of the controllable devices from said locked configuration to the unlocked configuration wherein the user interface of each of the controllable devices is configured to be operated independently of the controller device;
wherein the server system is configured for, prior to receiving the locking command signal from the controller device:
authenticating the controllable devices and the controller device, wherein the authenticating includes connecting the controller device to the server system via a locking channel, and connecting each of the controllable devices to the server system via a corresponding private channel, so as to subscribe each of the controllable devices to messages directed to each of the controllable devices;
setting a default state on the locking channel;
setting a default state on the corresponding private channel for each of the controllable devices;
sending a corresponding SUBSCRIBE message on the corresponding private channel for each of the controllable devices to force each of the controllable devices to subscribe to the locking channel;
and
sending a LOCK message on the locking channel in order to operate each of the controllable devices in the locked configuration.

11 more elements

A method of operating a learning management system using Representational State Transfer (REST), the method comprising:

a) receiving, at a server system, a locking command signal from a controller device;
and
b) processing, at the server system, the locking command signal and sending a corresponding locking control signal to controllable devices in order to simultaneously operate each of the controllable devices in a locked configuration wherein a user interface of each controllable device is controlled by the controller device while permitting user control at each of the controllable devices, wherein the permitting user control at the controllable devices comprises scrolling within restricted learning content;
and
wherein the method further comprises prior to step (a):
authenticating the controllable devices and the controller device, the authenticating including connecting the controller device to the server system via a locking channel, and connecting each of the controllable devices to the server system via a corresponding private channel of a plurality of private channels, so as to subscribe each of the controllable devices to messages directed to corresponding subscribed controllable device;
setting a default state on the locking channel;
setting a default state on the plurality of private channels;
and
wherein step (b) comprises, at the server system:
sending a corresponding SUBSCRIBE message on the plurality of private channels to force each of the controllable devices to subscribe to the locking channel;
and
sending a LOCK message on the locking channel in order to operate each of the controllable devices in the locked configuration.
