[nagdu] New technology for guy dog users.

[Buddy Brannan]

I'd be very surprised if average normal humans ever see this technology, given that it was developed as a university project. I'm not sure how much of this sort of thing we miss in real life...could be useful, could be superfluous, I don't really have an opinion.

>> Abstract: One of the challenges to working with canines is that whereas humans are primarily vocal communicators, canines are primarily postural and behavioral
>> communicators. It can take years to gain some level of proficiency at reading canine body language, even under the best of circumstances. In the case of
>> guide dogs and visually-impaired handlers, this task is even more difficult. Luckily, new technology designed to help monitor canines may prove useful
>> in helping handlers, especially those with visual impairments, to better understand and interpret what their working partners are feeling or saying. In
>> prior work a light-weight, wearable, wireless physiological monitoring system was shown to be accurate for measuring canines’ heart and respiratory rates.
>> In this paper, we consider the complementary problem of communicating physiological information to handlers. We introduce two nonvisual interfaces for
>> monitoring a canine’s heart and respiratory rates, an audio interface and a vibrotactile interface. We also present the results of two initial studies
>> to evaluate the efficacy of the interfaces. In the first study we found that many participants were more confident in detecting changes in heart and respiratory
>> rate using the audio interface, however most of the time they were just as accurate with the vibrotactile interface with only a slight increase in detection
>> latency.
