• Authors: Yang Trista Cao, Kyle Seelman, Kyungjun Lee, Hal Daum\'e III
• Abstract summary: In visual question answering (VQA), a machine must answer a question given an associated image. We evaluate discrepancies between machine "understanding" datasets (VQA-v2) and accessibility datasets (VizWiz) by evaluating a variety of VQA models. Based on our findings, we discuss opportunities and challenges in VQA for accessibility and suggest directions for future work.

• Abstract: In visual question answering (VQA), a machine must answer a question given an associated image. Recently, accessibility researchers have explored whether VQA can be deployed in a real-world setting where users with visual impairments learn about their environment by capturing their visual surroundings and asking questions. However, most of the existing benchmarking datasets for VQA focus on machine "understanding" and it remains unclear how progress on those datasets corresponds to improvements in this real-world use case. We aim to answer this question by evaluating discrepancies between machine "understanding" datasets (VQA-v2) and accessibility datasets (VizWiz) by evaluating a variety of VQA models. Based on our findings, we discuss opportunities and challenges in VQA for accessibility and suggest directions for future work.

  The problem of grounding VQA tasks has seen an increased attention in the research community recently. We propose a visual capsule module with a query-based selection mechanism of capsule features. We show that integrating the proposed capsule module in existing VQA systems significantly improves their performance on the weakly supervised grounding task.
