Abstract

This paper investigates new data exploration experiences that enable blind users to interact with statistical data visualizations—bar plots, heat maps, box plots, and scatter plots—leveraging multimodal data representations. In addition to sonification and textual descriptions that are commonly employed by existing accessible visualizations, our MAIDR (multimodal access and interactive data representation) system incorporates two additional modalities (braille and review) that offer complementary benefits. It also provides blind users with the autonomy and control to interactively access and understand data visualizations. In a user study involving 11 blind participants, we found the MAIDR system facilitated the accurate interpretation of statistical visualizations. Participants exhibited a range of strategies in combining multiple modalities, influenced by their past interactions and experiences with data visualizations. This work accentuates the overlooked potential of combining refreshable tactile representation with other modalities and elevates the discussion on the importance of user autonomy when designing accessible data visualizations.

• 視覚障害者が統計データ可視化(棒グラフ・ヒートマップ・箱ひげ図・散布図)にアクセスできるようにするため、従来の音声とテキストのモダリティに点字とレビューモードを統合して拡張したMAIDARを開発
  
  
  
  

• 11人の視覚障害者を対象にユーザスタディを実施

• 将来的には点字ディスプレイを分割し非言語と言語のモダリティを分割して提示したり、よりデータのフィルタリングや扱いやすいデータにするための操作を簡単にできるアクセスしやすいツールの需要がある
