2. Gives true feeling of
responsiveness
3. Feedback now, not later

18. What people say
Immediate
w h e n t h i n g s a re n o t
immediate
1. “The inconsistencies in the interface between apps and the occasional lag doing simple things like
scrolling in windows just screamed at me.” – James Kendrick (2011)
2. “That having been said, it unfortunately remains the case that Android [Ice Cream Sandwich] isn’t
as swift and responsive as iOS or Windows Phone (or even MeeGo Harmattan on the N9).”
“The subtle, pervasive lag that has characterized the Android UI since its inception is still there,
which is not a heartening thing to hear when you’re talking about a super-powered dual-core
device like the Galaxy Nexus.” – Vlad Savov (2011)
3. “Android, on the other hand, has always felt laggy to me.” - Mike Rundle (2011)

19. Suggestive
1. “Please enter date as
MM-DD-YY” is better
than “Invalid date
entered”.

h a p p e n s w h e n s u g g e s t i ve f e e d ba c k i s n o t p rov i d e d

20. Concise
1. KISSS – Keep It Simple,
Short and Silly.
2. Over clarification is a trap.
More feedback -> More Mass -> More instruction -> More alienation

21. Reassuring
1. Don’t cause the user to
worry about problem.
2. Relax the user and
suggest the remedy.
It does not mean
s a y i n g s ome s we e t
things to user.
H o weve r …

22. Reassuring
Comfort the user
with assuring
f e e d ba c k . Do n ’ t

perilous.

23. Some tips for repor ting feedback…

24. Error reporting
1. Acknowledgement: An error has occurred.

25. Notification reporting
1. Decide on severity of the
notification.

and manually closing
notification.

26. Catastrophic events
1. Don’t just bring about any
surprised change.
2. Accompany it with proper
feedback message.
