Mobile banking applications, one of the digital marketing tools, enable users to perform banking transactions quickly and easily. The way to create usable mobile applications is through detailed user experience tests. In user experience tests, eye tracking technique, which can provide reliable and detailed results, stands out. The purpose of this study is to compare the metrics and data outputs of two eye tracking techniques used to measure user experience: glasses-based (TobiiPro) and remote (Realeye) with a webcam. Eleven participants with mobile banking application experience were asked to perform two different tasks. During the procedure, in addition to the eye tracking technique, the system usability scale (SUS) was used as a method, and user opinions were also utilized as part of the think aloud protocol. As the output of the task-based procedure, findings on the mobile application experience were obtained, while the results of the data collected from different eye tracking techniques were also obtained comparatively. While close values were obtained in the average fixation time, it was found that the fixation amounts differed. Due to the differences in the findings between the techniques, it is recommended that further research should be standardized refresh rates across both eye-tracking techniques and test a larger sample to validate these findings.

Mobil Bankacılık Kullanılabilirlik Değerlendirmesinde Gözlük Tabanlı ve Uzaktan Göz Takibinin Karşılaştırılması

Öz

Dijital pazarlama araçlarından biri olan mobil bankacılık uygulamaları, kullanıcıların bankacılık işlemlerini hızlı ve kolay bir şekilde yapmasına olanak sağlamaktadır. Kullanılabilir mobil uygulamalar yapmanın yolu detaylı kullanıcı deneyimi testlerinden geçmektedir. Kullanıcı deneyimi testlerinde güvenilir ve detaylı sonuç alınabilen göz takibi tekniği öne çıkmaktadır. Bu araştırmanın amacı, kullanıcı deneyiminin ölçülmesinde kullanılan, gözlük bazlı (TobiiPro) ve web kamerası ile uzaktan (Realeye) olmak üzere, iki göz takibi tekniğinin metriklerinin ve veri çıktılarının karşılaştırılmasıdır. Mobil bankacılık uygulaması deneyimi olan 11 katılımcıdan iki farklı görevi yerine getirmeleri istenmiştir. Prosedür esnasında yöntem olarak göz takibi tekniğinin yanı sıra, sistem kullanılabilirlik ölçeği (SUS) kullanılmış ve yüksek sesle düşünme protokolü kapsamında kullanıcı görüşlerinden de yararlanılmıştır. Görev temelli prosedür çıktısı olarak, mobil uygulama deneyimine yönelik bulgulara ulaşılırken aynı zamanda farklı göz takibi tekniklerinden toplanan verilerin sonuçları da karşılaştırmalı olarak elde edilmiştir. Ortalama odaklanma süresinde yakın değerler elde edilirken odaklanma miktarlarının farklılık gösterdiği bulgulanmıştır. Teknikler arasında meydana gelen bulgu farklılıklarından dolayı, her iki göz izleme tekniğinde de yenileme hızlarının standartlaştırılması ve daha büyük bir örneklem üzerinde test yapılması önerilmektedir.
