Integrating a high-level 3D modeling interface into the freehand sketch reduces the human cognitive load in 3D creations. Modern CAD-based interfaces inhibit interactions with low-level controls and thus create a psychological niche. Here we intend to develop Isphere with 24 degrees of freedom to avoid the mental burden of low-level commands. Isphere is an intuitive device Integrated with 12 capacitive sensors that allows the design of objects using Top-down approach.The interface uses simple Push and Pull commands to interact with the user. We believe that Isphere can save a lot of time by ignoring traditional mice and keyboard-based modification.
Experimental results indicate that beginners in 3D modeling learn faster with help from Isphere. We affirm that Isphere is designed to minimize the barrier between the human cognitive model of what they want to accomplish and the computer's understanding of the user's task. Lacking reliability in its input mechanisms, this document suggests new improved algorithms for sensor control and new new methods for creating 3D models.
For designers, a quick method to demonstrate an idea or principle can be a freehand sketch. A sketch expresses an idea directly and interactively. The freehand sketch is a common way of modeling 2D objects, but for 3D modeling it will be complex and intuitive to visualize. Recent developments in computer aided design (CAD) help solve the problem effectively. It involves a series of low-level commands and mode switching operations to model a 3D object. This introduces a well-known problem for beginners to learn commands. It takes months to become an expert to create 3D models intuitively.
