Transcript of "USB Keyboard Analysis Using the Physical Interface Design Space (PIDS) Framework"

  1. 1. USB Keyboard Analysis Using the Physical Interface Design Space (PIDS) Framework Nata Gredina :: Qonita Shahab :: Brian Pagán
  2. 2. Introduction <ul><li>Modalities </li></ul><ul><li>Functional Description </li></ul><ul><li>Interface Parsing </li></ul><ul><li>Summary </li></ul>
  3. 3. Modalities <ul><li>Output gesture = TOUCH </li></ul><ul><li>Input modality = PRESSURE </li></ul>
  4. 4. Functional Description <ul><ul><li>Power: USB cable </li></ul></ul><ul><ul><li>Finger presses button </li></ul></ul>
  5. 5. Functional Description <ul><ul><li>Rubber grommet </li></ul></ul><ul><ul><li>Contacts pressure sensor </li></ul></ul>
  6. 6. Functional Description <ul><ul><li>5. Signal passed via membrane sheet </li></ul></ul><ul><ul><li>6. through control chip </li></ul></ul><ul><ul><li>7. to PC via USB </li></ul></ul>
  7. 7. Interface Parsing <ul><li>DoF: 2(# of keys) = 170 </li></ul><ul><ul><li>One input value </li></ul></ul><ul><ul><li>Two states </li></ul></ul><ul><li>Range: within body sphere; arms' reach </li></ul>
  8. 8. Interface Parsing <ul><li>Precision: 2 dimensions </li></ul><ul><ul><li>Selection </li></ul></ul><ul><ul><ul><li>Button series </li></ul></ul></ul><ul><ul><ul><li>2 bit resolution </li></ul></ul></ul><ul><ul><ul><li>Max 10 at once </li></ul></ul></ul><ul><ul><li>Time </li></ul></ul><ul><ul><ul><li>Fidelity: function of which key + duration </li></ul></ul></ul>
  9. 9. Interface Parsing <ul><li>Haptic Feedback: discrete 1/0 </li></ul><ul><ul><li>Tactile </li></ul></ul><ul><ul><ul><li>Grommet provides resistance </li></ul></ul></ul><ul><ul><ul><li>Feel key boundaries </li></ul></ul></ul><ul><ul><ul><li>Texture – F and J key </li></ul></ul></ul><ul><ul><li>Aural </li></ul></ul><ul><ul><ul><li>Hear keypresses </li></ul></ul></ul><ul><ul><ul><li>Indicates typing speed </li></ul></ul></ul>
  10. 10. Summary <ul><li>USB Keyboard </li></ul><ul><li>DoF = 170 </li></ul><ul><li>Range = Body sphere </li></ul><ul><li>Precision: </li></ul><ul><ul><li>Selection = 2 bits </li></ul></ul><ul><ul><li>Duration = repeated pulse </li></ul></ul><ul><li>Haptic Feedback = discrete </li></ul>
