In the past two decades, interaction for desktop computing systems has been dominated by graphical user interfaces (GUIs) that use a keyboard for text entry and a pointing device controlling an on-screen cursor for the majority of other tasks. These human-computer interfaces rely on the visual display system for two purposes: to provide data output, and to provide visual feedback. In this thesis we shall discuss why these interfaces are not the most appropriate on wearable computing systems, where the user's visual attention may be heavily loaded and input devices and display devices need to be compact and portable.;This dissertation presents a set of interaction techniques for touch-sensor-based input devices that address these issues. Our user interface systems are cursorless. Therefore, they do not rely on the manipulation and activation of on-screen visual widgets with the use of an on-screen pointer. Consequently, they minimize the amount of visual feedback that is needed during their operation.;We explore alternative input channels---in addition to position---that the human hand can manipulate and output channels that the finger can sense: multi-finger use, applied pressure, and passive haptics provided by tangible physical features. Here, the focus is on minimizing visual feedback requirements by transferring the versatility of GUIs that use on-screen widgets to the input device itself. A further goal is to offer expert users the possibility of eyes-free data entry and system control by exploiting the passive tactile physical features of the input device. We present the results of quantitative and qualitative user studies designed to evaluate our input techniques.;In addition to describing these input systems and their prototype implementations, we discuss sample applications developed to illustrate the use of these input techniques. We also discuss the applicability of these contributions to other fields of computer science: mobile augmented reality, immersive virtual reality, and interaction with public displays.
