Abstract This study proposed a classroom response system (CRS) different from existing commercial product. Modern and widespread used personal smart devices are utilized as the teacher-side controller and student-side response devices in the CRS instead of early infrared or radio frequency-based remote control. A prototype was developed for the proposed CRS, and it will be kept developing for further full functionality in CRS with the advantages and features of smart devices and modern network technologies.

Introduction A Classroom Response System (CRS) [1] is a technology-enabled learning system that allows instructors to project questions onto the screen, collects students’ responses immediately and reports the feedback results in a class. It is also called an Interactive Response System (IRS) [2], an Audience Response System (ARS) [3], or a Student Response System (SRS) [4]. A CRS consists of three major parts: hardware, software, and communications. As mobile technology advances, there are various smartphone or pad products appeared on the consumer electronics T.-W.

market and used in people’s daily life in recent years. These smart mobile devices are fully capable of serving as all-in-one computing devices and can offer a lot of potential applications, especially educational ones. In this paper, a prototype of smart device-based CRS is proposed. The objective is to develop a CRS with modern technologies and personal smart devices instead of earlier ones, and to make CRS more convenient by using smartphones or pads, now in widespread use, as user clients in the classroom.
CRS-Related Works Earlier CRS systems used specific controllers and infrared signals for user response transmission. For example, EduClick II [2] consists of infrared signal transmitters and a corresponding receiver. The transmission is one-way and works with direct line of sight. A radio frequency-based CRS [5] uses RF signals instead of infrared for response transmission. It has less limitations and disadvantages but still has limited signal transmission range. A web-based CRS [6] utilizes Internet infrastructures to transmit user response data, and uses web technologies instead of specialist software and hardware devices of IR and RF-based CRS. A mobile CRS is another type. In [7], a non-smartphone Java applicatio
