Holographic Touchscreens: Are They Worth It?
Touchscreen devices are used in countless applications, including both consumer and business applications. While most touchscreen devices rely on either capacitive or resistive technology to detect touch commands, manufacturers are continuing to explore new options, one of which involves holograms. Known as holographic touchscreens or touchable holograms, these devices are still relatively new but are quickly gaining momentum among manufacturers.

Overview of Holographic Touchscreens
A holographic touchscreen is a hologram-projecting device that supports touch commands. As with other hologram-projecting devices, it uses light diffraction to produce three-dimensional images in front of the device's screen. There are other devices that produce three-dimensional images, but they generally require the use of three-dimensional goggles or glasses. In comparison, holographic devices do not.
Holographic touchscreens go one step further by supporting the use of touch commands. They produce three-dimensional images by diffracting light in front of the screen. But they also allow users to control the device by touching the area in front of the screen.
According to Wikipedia, the world's first holographic touchscreens were invented in Japan. Shortly thereafter, the technology was refined by the computer chip manufacturing company Intel.
