Watch-Learning: Using the Smartwatch for Secondary Language Vocabulary Learning

Many long-term goals, such as second language vocabulary learning, can be achieved by leveraging one's fragmented time in daily life. In this paper, we explore Watch-Learning: using a smartwatch with speech recognition for learning and reviewing second language vocabulary. To evaluate the feasibility and efficiency of Watch-Learning, two studies were performed. One is to find out the differences in time overhead for vocabulary search on smartwatches and smartphones, and the other is to evaluate the frequency and the time cost of the "review" function on smartwatches and smartphones. The results show that, compared to smartphones, a smartwatch with speech recognition can save about 30 % time for vocabulary searching and can save approximately 70 % time when reviewing. Our findings are meaningful for designs of language-learning applications on smartwatches and can be extended to more micro-learning projects.
