The power of touch is profound. Research has shown that realistic haptic interactions with virtual objects decrease the amount of mistakes made, compared to traditional virtual reality training. In this blog we show you the types of haptic VR gloves there are, and how others use SenseGlove to their advantage.
“The next big step towards truly immersive VR training is to have haptic interactions. Therefore, Volkswagen collaborates with SenseGlove to make this vision of scalable haptic VR training a reality”

Haptic gloves for (manufacturing) research
Manufacturing can be a nightmare if not planned properly; VR could help with that. But controllers are often hesitant to start the process of implementing VR. Researchers looking to improve their designs use haptic gloves instead so users can get the feel of various tools, thanks to force feedback. Realistic simulations lead to higher production quality. Thanks to haptics, researchers can save time by optimising processes in the early stages of development.
Some jobs carry a significant health risk. Telerobotics comes to the rescue, allowing them to remotely handle dangerous tasks. However, lack of precision in operating robotic arms may lead to failure. That’s where VR haptic gloves come into play: haptic gloves allow the operator to feel the object as if they were holding it, and control grip strength precisely. Any hazard can be dealt with remotely, while maintaining precision and safety for both the robot and operator.
Haptic gloves for design evaluation
VR has surely transformed the design evaluation process, but it still fails to provide the user with a meaningful sensory experience. Haptic gloves can emulate the physical feel and texture of your design, helping you make the decision before investing in a physical prototype. They also allow you to efficiently adjust ergonomics on the fly. Force feedback makes the virtual interaction more realistic, so you can also evaluate the feel of interacting with your design.

With vibrotactile feedback, you can feel your design’s texture, how it moves and responds to the touch. This means that design teams can exchange feedback and implement changes in real-time, making iterations take minutes instead of months to complete.
“The SenseGlove’s interaction technology allows the user of the mixed mock-up to grab components and guide them to where they are to be assembled. The evaluation of the new confirmed that the improvements enable a more realistic simulation of the assembly processes and a more intuitive operation of the system.”
Florian Dyck, Researcher at Fraunhofer IEM
Machine learning for robotics
Using the SenseGlove and a VR-setup, the user gets immersed in a virtual environment, simulating vision and touch. During the simulation, the movement of the hand is used to control a virtual gripper arm. Haptic feedback is applied so the arm and gripper can be controlled in an intuitive manner. It is the task of the user to clear obstacles that are in the way of the virtual vehicle. The arm and gripper in the training environment are based on the existing model of the DOK-ING MV 4.
Many scenarios can be created in which obstacles have to be cleared. The obstacles will be randomly generated: the data output of the SenseGlove is used to feed the machine-learning algorithms. Using these algorithms, the vehicle will be taught to operate completely autonomous.
How to create haptic VR experiences
There are a couple of things you need to consider when creating a haptic experience:
1. Set the goal
Define whether you plan to research the influence of haptics, improve VR training results, or optimise the design process.
2. Choose a haptic glove with the features that fulfills your needs

What activities will your project require haptic feedback for: grabbing, holding, feeling vibration, impact, evaluating shapes or size of objects?
3. Define metrics to measure your success
How will you define success: the number of mistakes after the training/design process, time saved on design iterations, the number of instructors required for employee training, insights or citations to your research?
4. Create a pilot
SenseGlove supports Unity, Unreal Engine, ROS and other additional plugins. You can create a project yourself or ask the SenseGlove development team for help.
5. Test your interactions and see if the metrics are measurable
Test your metrics and see if there are new outcomes and insights that you can take into account.
6. Polish and launch your experience
Congrats! You made what’s digital feel real. Enjoy your results!
