Abstract

In recent years, Augmented Reality (AR) has gained popularity in various industries due to its ability to enhance efficiency, provide real-time information and data, and maintain user awareness of their surroundings. One of the applications of AR is in navigation, but most existing systems primarily focus on outdoor environments, neglecting indoor spaces. Mobile applications designed for indoor navigation often rely on expensive and computationally demanding beacons or natural markers to track the user's location along a predetermined path. Furthermore, traditional navigation estimation methods based on GPS are ineffective for indoor navigation. This study proposes a mobile AR application for indoor navigation that uses an intelligent signage algorithm based on fuzzy logic to estimate arrival time. The algorithm takes phone acceleration in the x and z directions as inputs and employs triangular-shaped membership functions for input and output variables. The experimental results indicate the feasibility of using fuzzy logic to estimate arrival time for indoor navigation, with an average prediction error of 5.82%.

ABSTRAK: Beberapa tahun ini, Realiti Terimbuh (AR) telah menjadi popular dalam pelbagai industri kerana keupayaannya meningkatkan kecekapan, menyediakan maklumat dan data secara masa nyata, dan mengekalkan kesedaran pengguna terhadap persekitaran sekeliling. Salah satu aplikasi AR adalah dalam navigasi, tetapi kebanyakan sistem sedia ada lebih menumpukan kepada persekitaran luar, mengabaikan ruang dalaman. Aplikasi mudah alih yang direka untuk navigasi dalaman sering bergantung pada bekon mahal dan memerlukan komputasi tinggi atau penanda semula jadi bagi menjejaki lokasi pengguna sepanjang laluan yang ditetapkan. Selain itu, kaedah anggaran navigasi tradisional berdasarkan GPS tidak berkesan bagi navigasi dalaman. Kajian ini mencadangkan aplikasi AR mudah alih bagi navigasi dalaman yang menggunakan algoritma papan tanda pintar berdasarkan logik kabur bagi menganggarkan masa ketibaan. Algoritma ini mengambil pecutan telefon dalam arah x dan z sebagai input dan menggunakan fungsi keahlian berbentuk segi tiga bagi pemboleh ubah masuk dan keluar. Dapatan eksperimen menunjukkan kebolehan menggunakan logik kabur bagi menganggarkan masa ketibaan bagi navigasi dalaman, dengan kesilapan anggaran purata sebanyak 5.82%.
