Virtual reality technology has made some significant progress in the past few years, but there are still some thorny issues that need to be resolved. Now, the project being conducted by the Hasso Plattner Institute in Germany can help developers solve one of the biggest obstacles to complete immersion.
When the VR experience shows the surrounding environment through the heads-up screen, its effect may be very convincing. However, when you reach out and touch nothing, immersion will quickly break. For this reason, a team led by Prof. Patrick Baudisch is trying to solve this problem by implementing tactile feedback.
According to a blog post published on the Hasselblad Plattner Institute's website, this project uses electric muscle stimulation to stimulate the user's muscle response. Dr. Portic’s team gives two examples: one is a large box that can be carried, and the other is a wall that is located in the environment.
The system they developed could stimulate up to four different muscle groups. It mainly achieves the required movement by activating the corresponding muscles, simulating the reaction of the user's body to the weight or resistance of the object.
The entire hardware device can be packaged in a small backpack while the sensors are connected to various locations on the user's arm. Although wearing backpacks and heads-up may cause slight inconvenience, Xiaobian thinks the technology has great potential.
The Hasselblad Plattner Institute has conducted two user studies and conducted field tests on the technology. Although their research will not necessarily translate into consumer products, it would not be surprising if the major VR vendors want to further expand this concept.
Many people think that VR itself is already very expensive, and additional hardware will further increase the cost. But regardless of the cost, the market always has a demand for high-quality VR experience, and this technology seems to be able to provide services for such people.
The tuning fork level switch is also often referred to as the tuning fork level meter or the tuning fork level controller, mainly because the tuning fork level meter appears in different links in industrial production, and actually plays different key roles, so people are habitual called many different names. Tuning fork level switch is a kind of level switch. It mainly uses the resonance principle of tuning fork to measure the level state. Its unique fork body design and its inherent vibration characteristics can ensure the automatic cleaning function of the tuning fork and prevent material hanging to the greatest extent. .
