Multimodal systems seek to support effective human-computer interaction leveraging people's natural capabilities. While screen-based touch, keyboard, and mouse input have been the mainstream, we see the growing popularity of speech input. Inspired by speech's fast, flexible, and expressive nature, I examine how speech input complements traditional touch input on smartphones in supporting self-tracking practices.
In this talk, I will describe several research projects that incorporate speech input into self-tracking systems. Specifically, I examine how people adopt speech and touch to capture different types of personal data in various contexts including exercise, food, and productivity. Taking a mix of research methods involving co-designing with healthcare professionals, in-situ data collection, and technology deployment, my research reveals the benefits and limitations of speech input in capturing structured and unstructured data, and expands our knowledge of how people practice self-tracking with natural language.
