Abstract

Fotokopi Topaz merupakan salah satu UMKM yang bergerak di bidang penyewaan jasa yang berlokasi di kota Palu, tepatnya di ibukota provinsi Sulawesi Tengah. Beroperasi dari tahun 1999 hingga saat ini, fotokopi Topaz masih menjalankan semua proses usahanya dengan cara manual. Dikarenakan hal tersebut banyak masalah dirasakan oleh pemilik usaha seperti, pemilik toko tidak mengetahui secara pasti stok barang yang terjual mau pun barang yang masuk dalam waktu tertentu, pendapatan dan pengeluaran yang tidak diketahui secara tepat dikarenakan data transaksi tidak seluruhnya tercatat di nota. Oleh karena itu,  untuk menyikapi permasalahan ini dibangun sistem yang dapat mengatasi masalah pencatatan stok barang, transaksi, dan pelaporan toko. Penelitian yang dilakukan berhasil membangun sistem informasi yang membantu dan mempermudah UMKM fotokopi Topaz dalam menjalankan usahanya. Sistem yang dibangun memiliki empat fungsi utama yaitu, mengelola data master, melakukan transaksi penjualan dan pengadaan, dan menampilkan laporan pendapatan dan pengeluaran.

Abstract

Eye tracking provides an alternative input modality to control the interactive contents in computers, particularly in assistive technology and public display. Instead of fixational eye movement, smooth pursuit eye movement has been used for object selection in gaze-based interactive applications. However, some previous works did not consider various similarity measures to match trajectory of eye movement and the presented dynamic stimulus. Furthermore, there was no correction towards the drift of eye movement during object selection. Hence, gaze-based object selection based on smooth pursuit eye movement is still inaccurate and unstable. To fill the research gaps, we proposed a novel approach for accurate gaze-based object selection using linear regression for eye movement’s drifting correction. We measured accuracy, success timing, and stability of object selection to validate performance of the proposed method. From the experimental results, object selection could be performed without the usage of chinrest using Euclidean distance, moving average and linear regression in gaze-based interfaces. The usage of chinrest did not give significant effect on accuracy, success timing and stability of object selection in gaze-based interfaces. The use of linear regression for predicting gaze points and correcting drift of eye movement has improved overall performance of object selection .In future, our results maybe used as a guideline for developing more accurate and more stable interactive applications based on smooth pursuit eye movement.
