“…Penelitian [19] menempatkan sensor di bandana kepala yang dapat digerakkan ke kanan dan kiri oleh sebuah motor servo sehingga menjangkau daerah yang lebih luas. Implementasi alat deteksi objek yang diletakkan di topi dilakukan dalam [20]. Alat bantu jalan dengan menambahkan sensor deteksi objek di kacamata juga telah dikembangkan [21], [22].…”

“…Alat-alat bantu tersebut hanya bisa mendeteksi objek rendah sampai tengah, sedangkan objek tinggi, seperti portal rendah, ranting pohon, atau objek setinggi pengguna lainnya, tidak bisa terdeteksi. Di sisi lain, alat bantu yang dipasang di bandana [19], topi [20], kacamata [22] atau berupa helm [18] hanya bisa mendeteksi objek tinggi sampai tengah. Sensor bawah S5 dalam kajian ini dapat mendeteksi objek rendah, seperti pagar pendek, batu, atau benda rendah lainnya.Sensor kiri S1, tengah S2, dan kanan S3 ditujukan untuk mendeteksi objek dengan orientasi horizontal dan disusun sejajar (Gambar 6).…”

Various electronic travel aids for people having visual impairment have been developed based on ultrasonic object detection employing the HC-SR04 ultrasonic proximity sensor. However, most of them do not consider blind spots where harmful objects cannot be detected. This study discusses the development of a vest that can detect objects in front of the blinds more widely and provide sound alert if an object in front is detected. This detector was developed based on an Arduino Uno equipped with five HC-SR04 ultrasonic sensors, and a mini DFPlayer module. In addition, blind area analysis of sensor detection is carried out to overcome objects that are not detected by similar studies. Horizontally, this travel vest sweeps objects up to 150 cm in distance with a 25o right or left angle deviation from forward direction. Vertically, object detection reaches up to 150 cm in distance with both upward and downward deviation of 30o from the vest.
