Usability og Interak1onsdesign SUMMIT -‐ konferencen København 22 maj 2013 Lars Bo Larsen Lektor, ph.d. Ins1tut f. Elektroniske Systemer Aalborg Universitet
Overview!
1. Introduction!2. Displayless Interaction (D-I)!– Example of Infinit project!– AAU, B&O and Radiometer!
3. Interessegruppen U&ID!
Motivation:!Common wish to investigate the potential of interaction with high-end IT devices without displays:!• ”Putting displays on devices is so nineties”!• ”Smart devices don’t need displays”!• ”Women hate LEDs and flashing displays in the home”!• “Displayless is the new high end, displays are
mainstream”!• “Displays are anti-social, require visual attention” !!
B&O’s BeoPlay A9 Radiometer’s ABL90
Iden1fied both research and commercial goals • Mul1tasking: Visual aUen1on demands more cogni1on than for
example tac1le • Removes visual aUen1on from interac1on • Research can be used on future products • Displays add complexity (designer are tempted to add) • Displays are lazy UX design • Cultural differences are minimized without visual indica1ons -‐ no
language • Cheaper produc1on and products • Displays are fragile and requires cleaning – beUer hygiene without • Simple and clean look
Experiment with perceived sound location!Main Problem:!– Displays can use e.g. flashing LEDs to steer the users
attention!– Can sounds give the user a particular directional
attention (cues) about where to interact on the user interface, without actually playing the sounds from the locational area?!
– Use generic sound patterns, not metaphorical sounds (e.g. birds twitter) to indicate direction!
– A generic pattern could be high or low tones, rising or falling and similar!
Psycho-acoustics and Human Perception!
• Humans can most accurately determine the origin of sound sources in azimuth (left-right), and less in the median-plane (up-down) !
• High frequency sounds are perceived to have its source placed higher than a low frequency sound, given that both sounds are transmitted from the same loudspeaker/source!
• Ecological psychoacoustics; humans perceive sounds as a part of context/product/sources, not in terms of frequencies. !
Experiment!• It is the information in the sounds
themselves, that guide the users to the correct location on the device!
Experimental design!
Results (are not yet available) Experiment is s1ll underway: – 50-‐70 test users, about 300 sounds per user/ 15.000 samples
• University goal: Iden1fy generic paUerns to form design guidelines – Publish results, generate new knowledge
• Companies goal: Design their own sounds – Use in products
In addi1on….
B&O and Radiometer work on own products and support research and students • 5 thesis students working on the project – Develop framework for UX work in Danish companies – Inves1gates efficient methods for early conceptual design – Inves1gates the poten1al of designing “mechanical sounds” to support users’ mental models
Infinit Temadag 20 juni • Vil du vide hvad vi finder ud af? – Infinits interessegruppe for Usability og Interak1onsdesign holder temadag I Aalborg den 20 juni
– Præsenta1on af resultater fra experimentet – B&O og Radiometer fortæller om deres designfilosofi – Stephen Brewster fra Glasgow, Skotland
