In recent years, more and more people have realized that emotion can affect their daily life in a certain extent. However, it is not easy to measure the emotion in a precise way. In this paper, we aim to extend the Sensual Evaluation Instrument to improve the self-report quality of emotion.

The purpose of this instrument is to obtain as much information as possible about people’s emotion, which contributes to make self-report more precisely. It will be used to detect participants' emotion information while they interacting with computer games. This instrument measures skin conductivity, pressure and movement data with touch sensors, force sensors and accelerometer. The activation area has been implemented in three ways: one is using RFID technology; the other two are using high performance LEDs and light sensors. All of the data which are collected from sensors will be transmitted to an Android phone via Bluetooth so that the designer can gather the information in real time. To make it more intuitive and user friendly, the data will be displayed as a plot on the mobile phone.

To implement this project, the instrument was built with Arduino Pro Mini with sensors embedded, data were collected successfully. An application is developed on Android platform 2.1 to receive and display data. A testing process was used to evaluate the working performance, which followed by some suggestion for the future improvement.
