Data mining pada bidang kesehatan dan manufacturing menjadi hal yang sangat penting dikarenakan suatu kesalahan klasifikasi (misclassification) akan memiliki dampak serius. Masalah utama pada data mining ketika data yang digunakan bersifat imbalanced multiclass karena classifier kesulitan untuk mengklasifikasikan data sehingga menyebabkan terjadinya misclassification. Solusi untuk meminimalkan missclasification dengan menggunakan metode cost sensitive pada classifier decision tree C5.0 dan naïve bayes. Penelitian ini menggunakan dataset glass, lympografi, vehicle, thyroid dan wine yang diperoleh dari UCI Respository. Kelima dataset dilakukan proses seleksi atribut menggunakan particle swarm optimazation. Kemudian dataset diuji menggunakan metode cost sensitive decision tree C5.0 dan cost sensitive naïve bayes.

Therefore, this research proposed an approach to help them using an electric wheelchair and control it using their eyeball movements. However, eyeball movement detection is still a problem due to the lack of standardized methods such as low accuracy for several gazes especially for downward and forward movements that caused by failure tracking mechanisms. Failure tracking mechanism mostly caused by failure pupil detection and tracking processes. According to the conducted research, there is a relation between eyeball movement and eyelid movement. Due to the relation, it can be concluded that the movement of the eyeball can be detected by utilize the eyelid movement without using the tracking mechanism. Hence, in this research, we propose an approach to detect the five movements of the eyeball using Eye-mark based on contour and edge detection. Our proposed method produces a brisk result with 91,2% of accuracy and better computational time compared with other marking methods. Accordingly, it is interesting on how to relate between eyeball movements and electric wheelchair navigation mechanism.

Smart wheelchair also developed with conventional mechanism that has more improvement in any aspect such as automatic system until control system. We develop a way for controlling smart wheelchair with movement of eyelid. In other ways, our system have capability to recognize state of the eye whether the eyes in opened or closed state. Opened and closed state in the eye can made a benchmark to control a wheelchair. In our research, we develop a system to recognize whether eye in the opened or closed state by using Multiple Method consisting of Haar cascade to detect eye location, Vertical Image Projection (VIP) to extract the feature and Learning Vector Quantization (LVQ) Neural Networks to recognize state of the eye. Our method produce an accuracy until 90.32% to recognize eye state. This approach can be used as an alternate way to control movement such go forward or stop by using their eyelid movement in smart wheelchair for disabled people.
