The dowel is only imaginary, of course-the hands are not physically linked, and the dowel does not exist. In the virtual environment, we show the participant a wooden dowel that they grip with each hand. Each controller provides the user with synchronous vibrotactile stimuli of different amplitudes. This VR equivalent of a carnival trick is known as funneling. We can even use this simple apparatus to produce a sensation of touch that “feels like” it originates in the completely empty space between your outstretched hands-an experiment we discuss in our paper in the current issue of Science Robotics. If we hand you a pair of controllers that can vibrate on command, we can play tricks. Sneaky (but, of course, highly ethical) experimentalists such as ourselves can render a completely computer-generated world. Virtual Reality (VR) is a great tool for revealing this strange and otherworldly foundation of our everyday sensory perceptions. But you’re seeing your fingers, hearing your fingers, and feeling your fingers-and all of these sensations fully correspond. Stretch out your hands and snap your fingers. The sense of touch (and indeed, all of our senses) is more or less illusory because no sensation stands alone.

2 pencil, the cool, smooth feel of a chalk-powdered blackboard, the gritty red bricks of the schoolhouse walls.

We can all remember the crisply beveled edges of our cheery-yellow No.
