Result of Survey 2

Questions 1-6

7. Which way do you prefer for modeling, creating or sculpting objects?

Reason for choosing creating:
- Don’t run out of stuff (but for sculpting, undo might help, or add to add as well as subtract)
Reason for choosing both:

- create base, sculpt rest

- also ability to start modeling with a blob or primitive shapes

8. If you have the chance, are you willing to use this tool for modeling?

 

 

-          It’s hard to do some detailed modeling

Feedback

-          It would be better if the user can tweak the speed in an option menu

-          Feel like using a mouse since using a wiimote to click

-          Set only one key for rotation

-          Moving the finger along the z axis for zoom in/out would be more intuitive

-          Implement finger actions like iphone (eg. scale)

-          Less buttons

-          Kind of tiresome

-          Stick the tape at the top of the finger would be better and natural

-          Translation seems not smooth enough

-          Rotation is awesome

-          Let users to choose which axis to rotate/scale/move

-          Put more reflective tapes on fingers

-          For the sculpting, the speed of removing cubes is too fast

-          Rotation of your head should be limited since when you move your head, your view moves away from the screen and you will be unable to see the screen

-          We should think about why we use these for modeling

-          Map the finger on the screen by using a dot to show

-          Dynamic changing effects should be changed

-          Short cut key to center view from different sides

-          Depth detection

-          It would be better to move the camera rather than to move the object

-          Implement adding cubes

-          Eraser (for sculpting)

-          Rotate by only using fingers

-          Bucket fill (for painting of sculpting part)

-          Use an arrow for visual feedback

-          Make a button to tell how hard you press it

-          The color of the cursor should be different from the color of the cube

-          A small screen as a navigator

-          Buttons and function mapping is not natural

i.e. A->scale,  B->move,  arrow key-> move & rotate

-          Having a background in the demo would help

-          Choose an audience and focus on making the platform useful to them, right now your audience seems vague. Figure out what is easy and fun to do with the interface and then work to support and encourage those users.

-          I think a push/pull Muddox type of modeling would be better for this application

-          Separate camera control/model control 

-          Use 2 sensor bar(IR) to do realistic 3D (rotating the sensor bar would rotate the world)

-          Different short cut key for different views(right, left, up, down)

-          Focus on/center image in perspective view

-          Something likes a UI for performing actions (eg. Painter, sculpt etc)

-          Would like to see the object really rotate 360 degree

-          Not only for modeling, I expect this is going to be something like a toy that I can play with

-          Translating is not as good as scaling and rotating

        -       Add deformable box control
