Abstract: We read to acquire knowledge. Reading is a common activ- ity performed in transit and while sitting, for example during commuting to work or at home on the couch. Although read- ing is associated with high vocabulary skills and even with in- creased critical thinking, we still know very little about effec- tive reading habits. In this paper, we argue that the first step to understanding reading habits in real life we need to quan- tify them with affordable and unobtrusive technology. To- wards this goal, we present a system to track how many words a user reads using electrooculography sensors. Compared to previous work, we use active electrodes with a novel on- body placement optimized for both integration into glasses (or head-worn eyewear etc) and for reading detection. Using this system, we present an algorithm capable of estimating the words read by a user, evaluate it in an user independent approach over experiments with 6 users over 4 different de- vices (8” and 9” tablet, paper, laptop screen). We achieve an error rate as low as 7% (based on eye motions alone) for the word count estimation (std = 0.5%).
