The document discusses concepts for future devices, including touchscreens, voice recognition, augmented reality, flexible screens, and wireless charging. Inputs could include advanced touch, gestures, eye tracking, and sensors. Outputs may involve augmented reality displays, holograms, and transmitting smells. Form factors may be flexible, connected to other devices like cars, or able to shape shift. The "killer device" of the future would seamlessly integrate these inputs, outputs and forms through cloud software and connectivity.
