How to use haptics throughout lever interactions
Our team has created a demo (watch it here) to show you how large is the spectrum of VR / AR experiences. In order to fully design your virtual experience and ease your haptic designs, we developed a never seen before graphical standalone tool to design, test and iterate your haptic experiences: Haptics Composer. In this blog post, we’ll dive into the implementation of haptics in VR development in interactions with levers. By using Interhaptics, we built a demo showcasing specific applications of haptics. The demo is highlighting the role of haptics in object manipulation.
Here’s a panel composed of specific objects which have well-defined movements. This panel is here to demonstrate the power of haptics to upgrade your VR environment. In each object section, all interactions are identical, all the levers will move up and down. What you see seems to be unaltered but that’s not the case. Haptic feedbacks are all different in each case.
Levers
When you create your XR scenarios, interactions can trigger events in your scenes. Doors opening, pulling levers, lifting rocks… Interaction Builder enables a fast creation of multiple and unique scenarios. Our suite has been developed for a wide spectrum of controllers and hand-tracking system.
The nature of a lever is very characteristic. Once their interactions are defined, their movements are always the same. Nevertheless, in our demo, there’s 3 different haptic feedbacks. The first lever represents a gradual feedback on different limits. The movement is “quiet” until you push the boundaries. We can easily imagine its use in a car simulation as a hand brake.
The second lever is more like a gearshift. Its haptic parameters represent a smooth rotation.
The last one contains an amplitude at the limit to alert the player.
Combinated lever
Unlike previous levers, the combinated lever demonstrates three different interactions with three haptic compositions on the same structure. The up and down motion has few haptic sensations. It was designed to feel like a lever with small cranks. Besides, you can notice its interaction is made with two hands.
The left and right motion on the lever has strong haptic feedback when reaching preset limits.
Last but not least, the rotating lever turns around its axis. You can sense the haptic feedback when a complete rotation is done. These are some interactions which you can find into race games or adventures games made with Unity or other game engines.
