New Haptic Technology Allows Users to Feel Like They’re Jumping Extra High in VR

Imagine being able to jump higher than ever before, feeling the sensation of weightlessness and gravity as you soar through the air. Thanks to a new haptic technology called JumpMod, this experience is now possible in virtual reality (VR). Developed by a team from the Human-Computer Integration Lab at the University of Chicago, JumpMod is a compact, wearable backpack that modifies the user’s perceived jump through a variety of effects.

By adding weight and motor acceleration to the backpack, users can feel the sensation of jumping higher, landing harder or softer, and being pulled higher or lower. This groundbreaking technology has the potential to revolutionize not only the gaming experience but also areas such as physical therapy and CGI acting. The researchers hope to continue exploring the possibilities of this technology and create even more physical sensations in a compact, wearable form.


In this comprehensive article, we will explore the exciting new technology called JumpMod, which aims to provide full-body sensations in virtual reality (VR). We will discuss the challenges in creating these sensations and how JumpMod tackles them. Additionally, we will delve into the importance of vertical space in sensory experience and how gravity can be simulated using weight and motor in the JumpMod backpack. We will also explore various applications of JumpMod technology, including its potential use in CGI. Finally, we will discuss future exploration and potential user studies of JumpMod, as well as its presentation and demonstration at conferences.

Introduction to JumpMod Technology

JumpMod is a revolutionary haptic device developed by the Human-Computer Integration Lab at the University of Chicago. This technology aims to provide users with a full-body sensation in VR by mimicking the feeling of gravity. Unlike other solutions, JumpMod is housed in a compact, wearable backpack, making it portable and untethered. By modifying the user’s perceived jump through five different effects, JumpMod opens up possibilities for hyper-realistic and immersive experiences at home.

Challenges in Creating Full-Body Sensations in VR

Creating full-body sensations in VR has always been a challenge due to the limitations of motion sensors. While these sensors can capture movement, they fall short of providing a comprehensive sensory experience. Traditional methods, such as motion platforms or large infrastructures with cables, are not practical for everyday use at home. The physics of generating large forces in a scalable, wearable device that can trick the human senses has posed a significant challenge. However, JumpMod offers a potential solution to this problem.

The Importance of Vertical Space in Sensory Experience

In the exploration of sensory experiences in VR, much attention has been given to the horizontal field, while the vertical space remains largely unexplored. Creating sensations like walking slowly can be relatively easy by adding wind resistance, but simulating the feeling of gravity when moving up or down is more complex. The team at the Human-Computer Integration Lab discovered that adding weight to the body in a controlled manner can effectively mimic the force of gravity. This finding highlights the importance of considering the vertical space in creating immersive experiences.

The Role of Weight and Motor in JumpMod

JumpMod utilizes a small weight and a motor to create the sensation of jumping higher or landing harder or softer. The weight moves up and down the user’s back in combination with the motor to add acceleration. During specific moments in a VR experience, the weight and motor are activated to create a push or pull on the body. For example, when the user tries to jump over an obstacle, the weight and motor move toward the top of the backpack, mimicking the upward force of the jump. When the user lands, the weight moves down at an accelerated speed, creating the feeling of impact absorption.

Applications of JumpMod Technology

JumpMod has a wide range of potential applications beyond gaming and entertainment. For athletes, applied gravity could help train muscle memory for specific movements. Physical therapy could benefit from JumpMod by providing a more realistic environment for rehabilitation exercises. Individuals with gravity-related fears, such as falling or climbing, could use JumpMod to overcome their fears in a controlled and safe setting. Moreover, the potential for JumpMod in CGI is intriguing, as it could enhance the performance of actors by providing a stronger sense of physicality and immersion while working in front of a green screen.

Feedback and Potential Applications in CGI

During demonstrations of JumpMod, the researchers received valuable feedback that highlighted its potential applications in CGI. Actors often struggle to get into character or embody a larger avatar when performing in front of a green screen. JumpMod can enhance their experience by creating a stronger sense of physical presence. For example, an actor playing the Hulk could benefit from the backpack’s ability to create a more realistic and immersive sense of strength when striking down their arm. This feedback opens up new possibilities for JumpMod’s application in the entertainment industry.

Future Exploration of JumpMod Technology

The team at the Human-Computer Integration Lab is committed to further exploring the potential of JumpMod technology. They aim to create more physical sensations while keeping the resulting prototypes small and compatible with everyday life. By expanding on the current capabilities of JumpMod, the team hopes to unlock the full potential of VR by providing not only visually immersive experiences but also realistic physics that “feel right.” Future research will focus on refining the technology and exploring new avenues for its implementation.

Presentation and Demonstration of JumpMod at Conferences

The researchers have already presented their work on JumpMod at the ACM CHI Conference on Human Factors in Computing Systems. Additionally, they conducted live demonstrations of JumpMod at the ACM SIGGRAPH conference, where over 300 people had the opportunity to experience jumping with the device. These conferences provided invaluable exposure for JumpMod and allowed for user feedback and engagement. The researchers shared details on how JumpMod works, the hardware used, and the results from three different user studies, providing a comprehensive overview of its capabilities.

Conclusion and Results from User Studies

In conclusion, JumpMod is an innovative technology that aims to provide full-body sensations in VR. By mimicking the feeling of gravity through weight and motor manipulation, JumpMod offers users a more immersive and realistic experience. The potential applications of JumpMod extend beyond gaming, including training athletes, aiding physical therapy, and enhancing CGI performances. The positive feedback and results from user studies demonstrate the effectiveness and potential of JumpMod, paving the way for further research and development in creating realistic sensory experiences in VR.
