Improved user interface methods and devices are provided. Some such devices are configured to detect a user's touch according to a localized diminution and/or interruption of guided optical signals. The devices may be configured for guiding light in a piece-wise contiguous array of optical blocks disposed on a flexible substrate. Alternatively, or additionally, the devices may be configured for guiding light along non-continuous optical fibers on a flexible substrate. These basic structures, or comparable structures, may be used to implement a wide range of tactile user interfaces.
