“…These studies rely on a face and a set of sketch recognition algorithms to generate domain-specific instructions and textual or on-canvas feedback. Studies [1,25] present an image-guided pen-based suggestive interface for sketching 3D wireframe models. Studies [12,14] support 2D/3D drawing practice and promote correction and improvement by comparing the user's imitation of a picture with the original.…”

In this paper, we propose an interactive system for controlling the pressure while cutting paper with a knife. Our system supports skill improvement for novices by measuring and evaluating their cutting pressure in real time. In this study, we use a knife with a blade attached to a stylus with a pressure sensitive sensor, which can measure the pressure, coordinates, and cutting time. We compare the cutting pressure values of novices with those of artists and thereby observe the difference in their cutting skills. We have also developed a practice system that guides the novices on controlling the pressure by providing information on the cutting pressure values of experts. This system shows the difference in pressure between novices and experts using a synchronous display of color and sound. Using these functions, novices learn to adjust their cutting pressure according to that of experts. The purpose of this research is to improve the cutting skill of novices learning the art of paper-cutting. Instructors typically teach the novices how to control the cutting pressure during paper-cutting workshops, as novices tend to cut paper with an unstable and higher pressure than necessary. Determining the right cutting pressure is a critical skill in the art of paper-cutting, and we aim to improve the same with our system. We verify the effect of our system by practicing paper-cutting in various methods and comparing the cutting pressure values obtained. It is evident from the results that novices who practice with our system show progress on the average and variance of cutting pressures.

“…These studies are evaluated based on input pressure. Studies [26] and [2] use an intuitive "ghost" metaphor and a first-person viewpoint for effective motion training. The result is an image of the subject performing gestures with the accuracy of an expert [3,20].…”

“…Users can also offset the reference plane by applying a three-finger pinch/spread gesture ( Figure 2: column 4, row 2). In this case, the magnitude of offset defined according to the area of pinching or spreading 1 . The one finger gesture provides a quick but imprecise method for offsetting.…”

“…The gestures defined for manipulating the reference plane form the basis of MobiSweep's work-flow. For any given state in the work-flow, the input gestures ( Figure 2: row 1) remain the same but the reference plane takes a different meaning 1 See supplementary material for details.…”

“…Thus, even sketching is perceived as a challenging medium by novice designers while communicating 3D forms [9]. While systems such as Every-bodyLovesSketch [1] cater to users untrained in sketching, they are focused towards the creation of detailed 3D sketches rather than quick design conceptualization. In this paper, we explore spatial design ideation through the association of physical human movement to the design outcome.…”

In this paper, we explore quick 3D shape composition during early-phase spatial design ideation. Our approach is to re-purpose a smartphone as a hand-held reference plane for creating, modifying, and manipulating 3D sweep surfaces. We implemented MobiSweep, a prototype application to explore a new design space of constrained spatial interactions that combine direct orientation control with indirect position control via well-established multi-touch gestures. MobiSweep leverages kinesthetically aware interactions for the creation of a sweep surface without explicit position tracking. The design concepts generated by users, in conjunction with their feedback, demonstrate the potential of such interactions in enabling spatial ideation.

This paper proposes a method that resembles a natural pen and paper interface to create curve based 3D sketches. The system is particularly useful for representing initial 3D design ideas without much effort. Users interact with the system by the help of a pressure sensitive pen tablet. The input strokes of the users are projected onto a drawing plane, which serves as a paper that they can place anywhere in the 3D scene. The resulting 3D sketch is visualized emphasizing depth perception. Our evaluation involving several naive users suggest that the system is suitable for a broad range of users to easily express their ideas in 3D. We further analyze the system with the help of an architect to demonstrate the expressive capabilities.
