Resumen
The article focuses on the future of user computer interfaces. There would be a shift from human-computer interaction to human-computing environment interaction and human-human interaction mediated by this federation of devices. Multimodal post-WIMP interfaces will combine multiple parallel sensory channels such as speech and gesture. Perceptual user interfaces will provide unobtrusive sensing and mimic aspects of human communication, reacting to one's identity, posture, gesture, gaze and even mood and intent. New capabilities will make it possible to come closer to meeting demands in user interfaces. The component technologies are still unsatisfactory. Particularly for virtual reality and augmented reality huge advances are needed in device technology to make them robust, unobtrusive, and with high spatiotemporal resolution. Computer scientists need to learn not just about human-computer interaction but also about underlying principles of perceptual and cognitive science, social science, and even the design arts to be able to make the most of human capabilities and limitations.
