Product Description Design SpecificationDetermine engagement with the The EEG headset will be used to determine the users engagement towards theeducational material by utilizing an material.EEG headset. The engagement levels will be output as a progress chart detailing the users attentiveness towards the material.Detecting Head and Eye movement to Hall effect sensors will detect the orientation of the wearers head relative to thedetermine engagement with the board.educational material. The eye tracking glasses will track the users eye movement relative to the front of the board.Ease of Use The device must track the wearers engagement without jeopardizing the wearers comfort. The headset must be adjustable to fit most head sizes. The eye tracking technologies must not obstruct the wearer during use. The setup and operation times for the device must be no more than 15 minutesReliability The device must be sensitive enough to detect all of the different signals in real time with negligible error. The data must also be collected and analyzed in a manner which validates the usefulness of the device.
