GI 2014 Publication! How Low Should We Go? Microsoft Research Internship paper #2

Today is a big day in the world of Michelle because I have lots of news to share! In addition to the CHI 2014 publication on the High Performance Stylus System, I am happy to report that I also have a follow-up paper that will be presented a Graphics Interface 2014 in Montreal entitled, “How Low Should We Go? Understanding the Perception of Latency While Inking”! (Yaaah again for no cell phone roaming fees to attend the conference!) As the paper is forthcoming, I can’t release all of the details but I can share the abstract and a short video that we shot. Once the full paper is available, I will provide a link to it.

Recent advances in hardware have enabled researchers to study the perception of latency. Thus far, latency research has utilized simple touch and stylus-based tasks that do not represent inking activities found in the real world. In this work, we report on two studies that utilized writing and sketching tasks to understand the limits of human perception. Our studies revealed that latency perception while inking is worse (~50 milliseconds) than perception while performing non-inking tasks reported previously (~2-7 milliseconds). We also determined that latency perception is not based on the distance from the stylus’ nib to the ink, but rather on the presence of a visual referent such as the hand or stylus. The prior and current work has informed the Latency Perception Model, a framework upon which latency knowledge and the underlying mechanisms of perception can be understood and further explored.

Although every accepted paper is cause for celebration, I am especially happy that this paper was accepted because the proposed Latency Perception Model is a nice summary of all the latency work that has been done by myself and others thus far. Here is the YouTube video summarizing our work:
