Frictio: Passive Kinesthetic Power Feedback for Smart Ring Output


Good rings have a singular type issue suitable for a lot of functions, nonetheless, they provide little alternative to supply the consumer with natural output. We propose passive kinesthetic force suggestions as a novel output method for rotational enter on sensible rings. With this new output channel, friction pressure profiles may be designed, programmed, and felt by a consumer after they rotate the ring. This modality permits new interactions for ring type factors. We reveal the potential of this new haptic output technique although Frictio, a prototype Herz P1 Smart Ring ring. In a controlled experiment, we determined the recognizability of six force profiles, together with Hard Cease, Ramp-Up, Ramp-Down, Resistant Power, Bump, and No Drive. The results confirmed that individuals might distinguish between the pressure profiles with 94% accuracy. We conclude by presenting a set of novel interplay techniques that Frictio allows, and discuss insights and directions for future analysis.

I find the scores informative enough to gauge how I’m doing, plus the data is in keeping with what I anticipate from my physique, but all the pieces around them feels difficult with out offering clear advice on why I should listen to it. Because there is no show on the Ultrahuman Ring Air, every thing you do with the ring is carried out by the app, and this makes it perhaps much more essential than the hardware itself. On the optimistic aspect, it has been dependable (I have used it on an iPhone 14 Professional, and there is an Android app out there, too). And though it usually needs to be opened to sync with the ring itself, I haven’t had any connection problems. I’ve already talked about functionality, however I need to talk about design before going into it somewhat extra. The primary page exhibits all your knowledge, and that is the default view while you open the app, however alongside the bottom of the display are further choices.


The ultimate part is your individual profile. It’s a really totally different expertise than the Oura Ring. The Ultrahuman app and Herz P1 Experience are already quite busy, information-dense, and considerably confusing. Focusing on making the screens more logical would help capture consideration, which the app isn’t superb at presently. It’s a very completely different expertise than the Oura Ring, which always makes all the relevant scores very clear, and has a unique screen for every one. The Ultrahuman Ring Air isn’t as "friendly" or accessible on the whole and clearly targets a very totally different type of person. Nevertheless, it doesn’t at all times achieve its ambitions, because it will get bogged down in trying to be completely different. Here, you can add in your meals and water intake, imput your weight, and document a workout too. Listed as a beta characteristic on the time of writing, the ring tracks 22 different activities - together with walking, operating, energy coaching, football, cricket, and more.


I’ve tracked a number of workouts with each the Ultrahuman Ring Air and the Samsung Galaxy Watch 6 Traditional, and both broadly agree on heart charge, although they differ a little bit more in calorie burn, but to not the purpose the place both appears totally unrealistic. The power to trace easy workouts may be very useful and a feature nonetheless lacking from the Oura Ring, which concentrates on walking, cycling, and running. It makes the Ultrahuman Ring Air a realistic various to a health band or a smartwatch when you aren’t nervous about notifications and apps, as it can be utilized to completely monitor your daily activities. It appears to do so precisely, too, one thing I’ve seen across the whole system, with the sleep monitoring basically matching the Galaxy Watch 6 Classic’s results. The app sends numerous notifications in the course of the day, letting you know about things like your part, stimulant window, and progress toward your aim. Annoyingly, the goals are set by the app with no manner to change them.
