Integrating a high-level 3D modeling interface in free-hand sketching reduces the human cognitive load in 3D creations.Modern CAD based interfaces inhibit interactions with low level commands and thereby creating a psychological gap
Here we intend to develop Isphere with 24 degrees of freedom to bypass the mental load of low-level commands.Isphere is an intuitive device embedded with 12 capacitive sensors which enables object design using Top-down approach.The interface uses simple Push and Pull commands to interact with the user.We believe that Isphere can save lot of time by bypassing traditional Mice and keyboard based mod- eling.
Experimental results indicate that novices in 3D modeling learn faster with the help of Isphere.We claim that Isphere is designed to mini- mize the barrier between the humans cognitive model of what they want to accomplish and the computer's understanding of the user's task.As Isphere lacks reliability in its input mechanisms, this paper suggest new improved algorithms for sensor control and new novel methods to create 3D models.
For designers, a quick method to demonstrate an idea or principle might be Free- hand sketching.A sketch expresses an idea directly and interactively.Freehand sketching is a common way to model 2D objects but for 3D modeling it will be complex and unintuitive to visualize.Recent developments in computer aided de- sign(CAD) helps to address the problem effectively.It involves series of low-level commands and mode-switching operations to model a 3D object.This introduces a well-known problem for novice to learn commands as it takes months to became an expert to create 3D models intuitively.
Why iSphere?
The aim of this research was to develop a high-level modeling system which can reduce human cognitive load in 3D creation.It creates a new dimension to interact with 3D models intuitively.It projects designers idea into 3D model instantly as Isphere will manipulate 3D objects in a spatial way.Simply, an input device that should make us to focus what is in our mind and built 3D models.As shown in the Fig. 1, isphere models an object through spatial method.
The hypothesis tested by conducting a study to compare the performance between command-based interfaces and Isphere.We claim that our approach to develop new 3D input interface is better than other research works conducted as it is a novel way to have '3D input interface'.
