Brief - Ryan

The real-time student feedback device allows students to give immediate feedback to teachers on how well they are understanding the material and how they are feeling. The teacher will be able to access all of the feedback over the internet and adjust their lesson accordingly. The students will have a device on their desk with a slider, four buttons, and a heart rate monitor. Each of these input mechanisms will convey different data to the teacher. The slider will convey how well each student is understanding the material. The buttons will be utilized for quick multiple-choice questions or surveys where the teacher can get immediate results. The heart rate monitor will continuously run and display to the teacher if the students are nervous or tense.

The current problem is that there is no communication between students and teachers on Zoom. People overwhelmingly have blank facial expressions for the duration of the call. The teacher is unable to tell if students are understanding the material. This device will bridge that gap.

This device is for students’ input, and there is an interface where the teacher can access this information.

The technology that this device uses is a linear potentiometer, four buttons, and a heart rate monitor. All of these components will be connected to an ESP32 board. All of the data collected will be available on an app or webpage via the internet and an MQTT broker. This will allow the teacher and students to be anywhere in the world and still receive the data in real-time.

The Real Time Student Feedback Device is designed to give teachers analog indicators of a students level of tension, and understanding, stress, and allow them to ask multiple choice questions. The foot slider portion of the device sits on the floor beneath a students foot(Left or Right), and rolls back and forth on a set of wheels. The two wheels are positioned beneath the front region of the arch, on either side of the slider. the position of the wheel is displayed to the teacher on a website. The tabletop portion of the device is designed to have the user's left hand rested on it. It has a slider, four colored buttons, and a heart rate monitor.

The designers think it is important for teachers to be able to see the levels of tension, the level of understanding, and the level of stress of their students. This is because teachers often use the behavior of their students, which is often not conveyed on zoom, to know if they should slow down or speed up the lesson. The floor slider works by checking the position of a potentiometer, a type of position sensor, that is attached to one of the wheels axle. The device correlates a foot position closer to the body to a higher level of tension. The device uses the tabletop slider as a way for students to have conscious input on their level of understanding. The heart rate monitor serves to measure the student's level of stress/excitement. the buttons allow the teacher to ask multiple choice questions.
