Creating three dimensional models with acceleration data

A computer-implemented method comprising:

• collecting a reference position as a start point responsive to a start point indicator;
• recording a time stamp associated with a time when the start point indicator was generated;
• collecting 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;
• recording a second time stamp associated with a time when an end point indicator is generated;
• creating a path dataset including the acceleration data, the start point, and the first and second time stamps;
• determining that no additional path will be followed by receiving a user input indicating that no additional paths will be traced;
• converting 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
• generating 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.
