  1. 1. Creating Digital Traces of Ideas : Evaluation of Computer Input Methods in Creative and Non-Creative Drawing

    Författare :Stanislaw Zabramski; Else Nygren; Antti Oulasvirta; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; evaluation; user performance; input methods; mouse; stylus; touch; tracing; ideation; Human-Computer Interaction; Människa-dator interaktion;

    Sammanfattning : Ideas are formed in a process of idea generation that includes creation, development, and communication of new ideas. Drawing has been used as a support for ideation for centuries. Today, computerized tools are commonly used for drawing. Such tools form a user interface between the human and the resulting drawing presented on the screen. LÄS MER

  3. 2. Large Vocabulary Shorthand Writing on Stylus Keyboard

    Författare :Per-Ola Kristensson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Sammanfattning : We present a novel text entry method for pen-based computers. We view the trace obtained by connecting the letter keys comprising a word on a stylus keyboard as a pattern. This pattern can be matched against a user-s pen trace, invariant of scale and translation. LÄS MER
