TactGlove is a haptic glove, meaning it provides the sensation of texture to your fingers and palms through the use of vibration motors. To be clear, though, it isn't a resistive glove – it can't make you feel as if you're holding an object.
Compared to the previous iteration the new DK3 increases the number of motors in each hand from six to eight, adding two new contact points in the lower part of the palm of your hand. At release they will come with a set of inner gloves, but for the demos at AWE, the reps were using disposable gloves. I was thankful for this when I finished my demo and noticed how sweaty my hands were.
Hand tracking in XR has come a long way and some developers like Owlchemy Labs are bullish on it, but it is fair to say controllers will remain the predominant input system of choice in VR gaming for the near future. It feels like a tough ask, in the current VR gaming ecosystem, to expect game developers en masse to not only adopt hand tracking as a primary input, but take it a step further and devote time and resources to adding support for a fairly reasonable, but still costly accessory in a struggling market. It is telling that many developers who have already added hand tracking support to their games, like Owlchemy Labs and Resolution Games with the Demeo series, have not already taken this step.
That all said, the DK3 gloves are great, addressing the user feedback that the haptics were limited to fingertips and thankfully offering enough size options to fit most players. Like all of bHaptics' products, modded game support is available for those willing to put in the time to develop it as well.
