An appearance-modifying device for modifying the visual appearance of a surface covered thereby, the device comprising a first substrate, a second substrate, a spacer structure spacing apart the first and second substrates in such a way that a space between the first and second-substrates is divided into a plurality of cells wherein in each cell, an optically transparent fluid having a plurality of particles is dispersed therein, wherein each of the cells is configured such that a distribution state of the particles is controllable in a first distribution state and an appearance of the surface covered by the appearance-modifying device is determined by optical properties of the particles and a second distribution state in which the particles are concentrated onto one of a first particle concentration site and a second particle concentration site.

Appearance-modifying device, and method for operating such a device

An image display including a touch-sensitive display, that creates tactile sensation and movement of an object (-) along its surface is provided. Actuators including conductive rods (--) attached together may be used, such that each rod of the actuator (-) may increase or decrease in size when current is applied to that rod to cause the actuator to bend toward a specified direction. Also, an image display that includes ball bearings (-) whose rotation is controlled by driving magnets (--) to cause an object to move is provided. Further, air holes (-) tilted in various directions to control object movement by air pressure may be provided. Moreover, rods (-) may be moved up or down as activated by driving magnets (-). The actuators, rods, ball bearing assemblies, or holes may provide touch sensitivity for the image display.
