Microsoft developed 3D tactile feedback touch screen: doctors can touch the tumor

Microsoft is developing a 3D haptic feedback touch screen that uses haptic feedback technology to enable users to clearly feel the shape and weight of objects on the screen. The results of this research can help doctors explore human body scans, and doctors can navigate the different locations of brain slices by touching the screen.

Earlier, it was reported that Microsoft is also developing a 3D haptic feedback touch screen that uses tactile feedback technology to provide feedback to users through resistance and vibration, allowing users to clearly feel the shape and weight of objects on the screen.

This 3D haptic feedback touch screen includes an LCD flat screen, multiple force sensors, and a robotic arm that can be moved back and forth. Specifically, when the user touches the screen by hand, the system generates a slight resistance to ensure that one finger of the user is in close contact with the touch screen. If the user presses the screen again at this time, the robot arm of the system will smoothly move the screen backwards accordingly; if the user withdraws some power, the robot arm will smoothly move the screen forward accordingly. At the same time as these actions occur, the computer will adjust the size and angle of the objects in the screen according to the corresponding feedback resistance to generate a 3D rendering. If there are several different texture cubes on the screen, the stone cube needs more force to push, while the sponge cube needs less force.

Microsoft said the findings could help doctors explore human scans. To this end, Microsoft produced a demo that showed the use of magnetic resonance imaging (MRI) to scan the human brain, and doctors can navigate the different parts of the brain slice by touching the screen. In the demonstration, the doctor can also draw notes and mark a tactile brake, or force feedback marker, so that it can be quickly found. Microsoft researchers say that over time, this mark can be extended to mark potential lesion problems. "Imagine a tactile feedback when you touch an abnormal area, such as a tumor. The system can Different touch objects set different feedback responses."
