4 pointing Keyboard Short-cuts communicating an alternative way to access the command. what might be the problem with this type of communication regarding the gulf of competence? menu revelation Widgor and Wixon, Chapter 20: selfrevealing gestures, in Brave NUI World 5

5 ExposeHK W M D H T 2 pointing idea: display hotkeys at the position of a button when holding down command key menu revelation Literature: Malacria et al. Promoting Hotkey Use through Rehearsal with ExposeHK CHI 13 6

6 ExposeHK W M D H T 2 pointing menu revelation Enable hotkey browsing: use mouse pointing to get short-cut feedback to commit it to memory creates a performance dip discourages hotkey use, traps user in pointer-based beginner mode browse without pointing action. Literature: Malacria et al. Promoting Hotkey Use through Rehearsal with ExposeHK CHI 13 7

7 ExposeHK W M D H T 2 pointing menu revelation Enable physical rehearsal: guidance should be a physical rehearsal of the way an expert would issue a command (Kurtenbach) use the same modality for browsing and rehearsing hotkeys. Literature: Malacria et al. Promoting Hotkey Use through Rehearsal with ExposeHK CHI 13 8

8 ExposeHK W M D H T 2 pointing menu revelation Rapid hotkey identification for intermediate user: exploit the expert behavior people already have (e.g. spatial memory and knowledge about virtual environment) Literature: Malacria et al. Promoting Hotkey Use through Rehearsal with ExposeHK CHI 13 9

10 take-away message Models inspire a whole set of novel opens a new perspective e.g. the separation of motor vs. display space apply knowledge to all other pointing devices similar to a mouse or understand the difference to other input devices to spark new to enhance input. Concepts enable you to have new perspectives on design. reapply concepts in different interfaces! 11

12 Overview Pointing devices light-gun light-pen (sketch pad) mouse pointing stick Alternative shapes curved displays Curve Alternative styles free-hand whole body Videoplace Bridging the gap between digital and physical world 13

13 Light Gun: Robert Everett early 1950s reads the position of a dot on the screen of the Whirlwind identified aircrafts on the CRT of SAGE air defense computer (1956) Photo from Computer Encyclopedia, 2000 The MITRE Corporation Archives. 14

14 Lightpen (1957) stylus shaped follow-up of a Light Gun first with a pen-shaped device on a screen 15

15 Lightpen (Sketchpad by Ivan Sutherland) 16

16 key concepts introduced by Sketchpad buttons, knob, switches for commands and constraints light pen pointing technique: cursor snaps to line bimanual Innovation of problem solving 17

17 Key Innovation of Sketchpad traditional computers: understand the problem well identify steps necessary to solve problem punch cards literal minded very elaborated calculating machine Solving a problem step-by-step begin investigating a problem and its solutions human-computer cooperation, human assistance computer seems to have intelligence 18

18 Do computers today support problem solving? 19

19 Mouse (1964) Douglas Engelbart patented in 1967 demoed in 1968 integrated in the computer system NLS (on- Line System) 20

35 Designing for mobile technological perspective: It s technology that we can carry around (portable) phones, smart watches, google glasses, interactive cloth, etc. body-centric perspective It s an interface where input/output is performed relative to the body. same technology needs to be designed depending on its position on the body same technology can be controlling objects fixed in the world The body s spatial relationship with an input device effects design (how you hold a phone effects touch ) 39

36 do you think of your phone as stand-alone device? input and output distributed in the environment. how to design for such environments? 40
