Abstract

Obtaining physical model data for CAD model generation with a process that includes: receiving a first acceleration-based path data set including acceleration data for an accelerometer device as it was traced over a first path along the surface of a physical object, converting the first acceleration-based path data set to a first position-based data set including position data for the accelerometer as it was traced over the first path along the surface of the physical object, and generating a three dimensional object model data set based, at least in part on the position data of the first position-based data set.

First claim

What is claimed is:

1 . A computer program product comprising a computer readable storage medium having stored thereon:
first program instructions programmed to collect a reference position as a start point responsive to a start point indicator; second program instructions programmed to record a time stamp associated with a time when the start point indicator was generated; third program instructions programmed to collect acceleration data generated by an accelerometer by following a first path on a physical surface of an object with a device in contact with the physical surface, the device including the accelerometer; fourth program instructions programmed to record a second time stamp associated with a time when an end point indicator is generated; fifth program instructions programmed to create a path dataset including the acceleration data, the start point, and the first and second time stamps; sixth program instructions programmed to determine that no additional path will be followed by receiving a user input indicating that no additional paths will be traced; seventh program instructions programmed to convert the path dataset to a position dataset including a set of sequential positions corresponding to positions of the device while following the first path; and eighth program instructions programmed to generate a three-dimensional object model based on the position dataset, the three-dimensional object model data set including data to represent the object as a CAD model; wherein: the device is configured to determine the acceleration data and the reference position; the start point indicator is generated by a user touching a touch screen of the device; the end point indicator is generated when a user no longer touches the touch screen of the device; and the acceleration data includes acceleration-type motion data.
