Usability Analysis of the Novel Functions to Assist the Senior Customers in Online Shopping.
Lecture Notes in Computer Science(2018)
摘要
Online shopping provides a convenient and diverse shopping experience. However, elderly customers are unable to leverage such benefits due to their age-related impairments or lack of computer knowledges. To solve this problem, we extend our previous e-commerce website design with novel assistance functions including multimodal search and personalized speech feedback. In this paper, we evaluated the usability of these functions through a phenomenography based qualitative study. From the results, we found out several biases which affect senior users' interaction with the assistance functions. Firstly, there is a gap between the icon metaphor and the senior users' real world experience. Secondly, consistency is more important than flexibility in e-commerce website design for the elderly. Thirdly, senior users tend to show less interest to explore the website than younger ones. These findings and considerations will guide us in the following rounds of age-friendly assistance function designs to improve the senior user's online shopping experience.
