股票市场图表指导投资者做出金融决策。在线股票市场图表在很大程度上是交互式的，由实时金融数据驱动。然而，这些图表通过屏幕阅读器不容易获取。为了使屏幕阅读器用户能够查询并有效使用交互式在线股票市场图表，我们正在开发一种名为ChartMaster的工具。在本文中，我们描述了一项针对16名视障人士进行的早期研究，其中大多数是金融新手，目的是共同设计ChartMaster的交互界面。进行了一项包容性设计实践，以探索使用非视觉模式与股票市场图表进行交互的替代界面。采用人机交互方法进行了以用户为中心的共同设计过程，以迭代评估和完善三种输入解决方案：音频输入、文本输入和下拉菜单。虽然用户最终宣称下拉菜单是三种解决方案中最有用的，但他们希望根据任务情境和个人偏好有所有可能的选项可供选择。用户反馈证实，一刀切的设计对于在尽可能广泛的情境范围内满足不同用户的需求并不理想。还发现带有下拉菜单界面的ChartMaster工具对金融新手具有潜在的教育价值。
Stock market charts guide investors in making financial decisions. Online stock market charts are largely interactive, driven by real-time financial data. However, these are not easily accessible via a screen reader. To enable screen reader users to query and effectively use interactive online stock market charts, we are developing a tool called ChartMaster. In this paper, we describe an early study conducted with sixteen visually impaired persons, most of whom were financial novices, for co-designing the interaction interface for C hartMaster. An inclusive design exercise was undertaken to discover alternative interfaces using non-visual modalities to interact with stock market charts. A user-centered process of co-design using HCI methods was carried out to iteratively evaluate and refine three input solutions: audio input, text input and dropdown menu. While the users ultimately declared the dropdown menu to be the most useful of the three solutions, they wanted all possible options to choose from based on task contexts and personal preferences. User feedback confirmed that a one-size-fits-all design is not ideal for accommodating diverse user needs within the widest possible range of contexts. It was also found that the ChartMaster tool with dropdown menu interface holds potential educational value for financial novices.
