Computer Input Device/Technique to Increase Efficiency in Design Software

Patrick O’Connor

» Ergonomic keyboards manipulate hand and shoulder positions to adapt a more healthy posture

Splay Separation Tented

» Bent Wrists

» Major factor in RSI occurrence » Often angled the keyboard slightly to the right » Switched from straight to bent wrists

» Largely Favored the Index Finger

» Index finger was used for hard to reach keys » Results in extra movement » Results in awkward positions

» Right Hand Did Most of work, Left Hand Remained Largely Idle

» Disproportional workload between hands » Combined with mouse, further increased workload for right hand

» Enjoyed typing

» Had to have keyboard tilted forward

» Most common mistakes made are from not pressing keys hard enough due to speed

» Does not use shortcuts often, ALT TAB to switch windows

» Believes the inverted comma button is too close to return key, encourages mistakes

» Felt pain in hand and wrist area, believed this was from moving the keyboard too close to him

» Reason for not investing in ergonomic keyboard was cost

» Would learn new layout to increase speed

» Suggestions: Autocorrect, don’t aim just press roughly where keys are

» Speed » Kept keyboard straight » Tilted screen back » Large amount of mistakes » Never looked at keyboard » Rested hands in ready position

» Ergonomic keyboards have limited market » Dominant design in Keyboard layouts » Main problems with computer accessories are a) Pain in neck b) Finger clicking of mouse c) Outward rotation of shoulder

Ultimatum

» New technology of computing interaction » New Product to prevent RSI

» Product for the workplace or home use? » Productivity or user experience?

» The market is there

» Wider scope of needs

» Wider scope of solutions

» Obsolete technology worry

» Susceptible to RSIs

» Drawing Tablet user never looked at device » Flipped stylus quickly and without looking » Tapped pad with stylus for mouse click » Had to switch to mouse or keyboard for

some tasks » Minimized movement all over » Had to switch to mouse or keyboard for

most tasks » Used all fingers to grip » No buttons

» Wrists were often bent » Often had to lift up mouse when rotating a 3D

model » Right hand was often use for mouse and key board » Awkward finger positions on mouse when middle

button pressed » Shortcuts rarely used » Mouse was used whenever possible

» Users often don’t use the most efficient way to complete a task

» Often adapt awkward positions with existing devices » Users predominantly use their right hand » Index finger is used for most frequently for applying

pressure » Often switch between devices » A large amount of time spent in menus » Holding buttons for long periods results in aches » Design focus should either be for home use or
