Cold Warmer Hot

Observations on navigating and searching using cold, cooler, warm, warmer, and hot.

Scenario 01
“Warm, warmer” keeps participant on path.
“colder” drastically changes participant’s direction.
Spends 47 seconds to get into close proximity (5 feet)
Spends another 1:00 getting into 1 foot proximity.
Spends another 20 seconds reviewing the same area.
Spends another 30 seconds searching within a 2 foot proximity
Takes a total of 2:17 to find a set of keys within 15 feet of starting point

Scenario 02
“Warmer” prompts search in close vicinity.
“Cooler” prompts change in direction and search
1:20 to get into 5 foot proximity
another 1:00 to get into 1 foot proximity
total of 2:30 to find a set of keys 30 feet from starting point.

Scenario 03
“Warm warmer” prompts light search
“Luke warm” mentioned to give scale of warmth.
1:00 to get within 5 feet
12 seconds later, keys found
total of 1:12 to find keys within 30 feet of starting point.

Scenario 04
spends first 1:11 within 5 feet of starting point
then starts heading in longer strides
22 more seconds to get within 5 feet
another 45 seconds seaching within 2 feet
total of 2:18 to find keys within 25 feet of starting point.

Scenario 05
“Warm” prompts pause
40 secs to get within 3 feet
Spends another 55 seconds searching within 3 feet
another 1:08 concentrating within 1 foot proximity
2:43 finds keys within 15 feet of starting point.

Participants need a second level of specificity when they are within 1-3 feet of the object they are searching. It seems the guidance at closer proximity requires a higher resolution, both in response time of the guidance to the participants movement as well as the guidance’s response to the distance from the participant’s hand to the object.

Levels of warmth are hard to guage since the participant doesn’t have any indication of how warm the current warmth is, or how much warmer they could get, prompting searches in areas that are far from the object.
