microsoft develops 3d touchscreen with tactile feedback

Details of the touch screen showing 3D images have been released by Microsoft\'s research department.
The project combines the LCD flat screen with the force sensor and the robot arm moving back and forth.
By controlling the resistance of the user\'s fingertips, the company says it can simulate the shape and weight of the object displayed on the screen.
Microsoft says the device can be used not only for games but also for medical care.
Work on the project is taking place at Redmond campus near Seattle.
When one touches the prototype, it pushes back with a light force to make sure one of their fingers is in contact with the screen.
If they press it, the robot arm immediately pulls the screen back in the smooth motion of the match.
If they start to retract their fingers, they move towards them.
At the same time, the computer will adjust the size and perspective of on-
Screen graphics for creating 3D effects.
The trick to simulating body touch is to adjust the number of forces --
Feedback resistance.
So, in an application where a graph representing different square blocks is displayed on the wall, a piece of \"stone\" needs a relatively large force to push it off the ledge, a \"sponge\" requires less force.
In addition, when a person drags his finger onto the surface of a virtual object, the kit can provide a sense of shape by adjusting the position of the screen to match the profile of the virtual object.
\"When your fingers push the touch screen, the senses merge with the stereo vision, if we blend correctly and constantly update the visual effects so that they correspond to the depth perception of your fingers, michael Pahud, a senior researcher, said: \"This is enough for your brain to accept that the virtual world is real. \".
His team uses the technology to allow users to feel the shape of the virtual cup and ball while using special glasses to view the shape of the virtual cup and ballvision effect.
One use of the device, Microsoft suggests, is to allow doctors to do physical scans.
It creates a demo using magnetic resonance imaging (MRI)
Scan the brain to show how doctors can browse different slices by pushing their fingers to the display.
It also allows them to draw notes and leave a \"tactile tent \"--or force-
Feedback marking-
In some layers, it is easier to find them later.
Researchers suggest that this can be extended in a timely manner to mark potential issues.
\"I can imagine that when you encounter abnormalities, such as tumors, you get tactile feedback because we can change the response based on what you touch,\" Mr Pahud said . \".
\"You have a different reaction when you touch soft tissue and hard tissue, which makes you have a very rich experience.
A medical tech expert said the project showed hope, but added that previous efforts to try to use touch
Feedback on robotic surgery and other Health aspects
The relevant equipment shows that its response capability is not reliable enough.
In particular, Dr. Peter Weiler, director of the City University of London Health Information Center, said he was concerned that Microsoft\'s screen could not display the texture accurately.
\"If you move your fingers to a rough surface, the screen will have to move up and down quickly to make that impression,\" he told the BBC . \".
\"The examples they gave went well --
Square and cylinder and everything.
But if you want to use it in the real world, it has to react to the rapidly changing shape.
\"Other people are working on different ways to provide touchfeedback. California-
For example, a screen with a tiny fluid channel has been developed based on Tactus, allowing the pop-up to simulate the feel of the button.
Dr. Weiler suggested that if this or other technology could be combined with Microsoft\'s current research, its screen could indeed find a way to use it.
He said: \"I think the example of their brain scan is a bit artificial, but I think it is useful for doctors who do remote counseling . \" \"This means that the patient may be in another country or hospital and the doctor can feel their glands or abdomen from a distance.
