  199. 199. Wait, what was all that? If you must measure context – use multiple sources Repair and negotiate – never assume you’re right Use least collaborative effort – time, error, shared knowledge Keep track of what this is – remember across interactions Allow users to negotiate context between themselves, too Use pre-sequences to set up interactions Extra information should enrich context – don’t distract What really matters is relevance – focus on that 200 Friday, 17 January 14

  208. 208. GOMS KLM Mentally preparing Keying (average typist) Homing Pointing Waiting for a response M = 1.35 sec K = 0.2 sec H = 0.4 sec P = 1.1 sec R=? Icons: The Noun Project and Camila Bertoco Friday, 17 January 14 209
  209. 209. Rules (simplified) Walk through the interface step by step. List the Mental Preparation (M), Keying (K), Pointing (P), Homing(H) and Response times (R). Place Ms in front of all Ks and Ps Delete Ms between Keying characters in a single unit (like a word or a sentence) But keep the first M (thinking what to type). Delete Ms that come between Pointing and Keying (so PMK becomes PK) 210 Friday, 17 January 14

  213. 213. Design challenge Feel my pain Every conference call I have starts with people turning up late, losing the connection or having software problems. Help me: fix Skype. Things to consider Think about what makes a meeting work offline. How would those things happen online? What are the key phases in a meeting - from planning to conclusion? How do you make meetings visual? Letting people share documents or see ideas? How do you keep all that simple? What causes the complexity? 214 Friday, 17 January 14
  214. 214. Design challenge Feel my pain I’ve got a Microwave oven that will also grill or bake. But I’ve no idea how to use it. Normally I just click the ‘on’ switch repeatedly to add 30 seconds to the total. And that switch has worn out! Things to consider Lots of food packets have microwave instructions - could you make this oven work with them? How do I know whether I’m microwaving, grilling or cooking? What’s the real objective here? What do I really want from this product? 215 Friday, 17 January 14
  215. 215. Design challenge Feel my pain I’m tired of going to the basement to manually turn the heating on and off. Make me a central heating controller I can understand. Things to consider This is a thermostat for a British house – so there’s no air conditioning. The hot water tank and central heating can be programmed independently. It can be cold during the summer and warm in the winter. What use can you make of the patterns that are already in my head? Buttons, displays, wireless connections, software… all cost money. This is a cheap device. 216 Friday, 17 January 14
