How well do you know collaborative sketching and templates?

Collaborative Sketching and Templates

• Collaborative sketching involves group interaction around a sketch, with the conversations around it being as valuable as the sketch itself.
• John Tang categorized every person's activity in collaborative sketching according to the action and function it accomplished, such as listing, drawing, and gesturing.
• Templates can be used in situations where only a portion of an existing visual interface needs to be modified, leaving drawing space for creative endeavors.
• Templates can be created by finding a source image of the desired interface, importing it into a bitmap editor, and white-out the areas to be used as a sketching surface.
• Tracing can be used to keep everything at the same sketch fidelity and mute unneeded details when creating a template, by creating a new layer and tracing over the parts of the image to be kept.
• Sketching with pen or pencil is often faster and more convenient than drawing in software, and multiple copies of the template can be generated by photocopying or scanning and printing the traced image.
• The collaborative sketch serves a somewhat different purpose than sketches done individually.
• The paper used for collaborative sketching should be large enough and the table small enough so that all can reach into the drawing area easily.
• Gesturing in collaborative sketching involves purposeful body movement that communicates specific information, such as pointing to an existing drawing.
• Functions of collaborative sketching include storing information, expressing ideas, and mediating interaction to facilitate group collaboration.
• Templates can be created from pre-determined and fixed portions of a visual interface, such as the shape of the hardware product or a layout/style sheet.
• Appropriating photos can be used to create templates, by finding a source image of the desired interface and importing it into a bitmap editor.
