Algorithm 3 WEAR-IT API use in MoveUp.

Require: $s p$
Ensure: $s, w d, d a t a_{s}$
Comment: scan the wearable environment
${P u l s e O n^{T M}, \dots} = s c a n (s p), i \in [1 \dots k]$
Comment: connect to $P u l s e O n^{T M}$ suitable for the application
$c o n n e c t (P u l s e O n^{T M}, s p)$
Comment: identify the sensors in the $P u l s e O n^{T M}$ wearable device
${s_{P u l s e O n^{T M}}^{j}} = c l a s s i f y (s e n s o r s (P u l s e O n^{T M})), j \in [1 \dots m]$
Comment: select the needed sensor of type HEART_RATE
$s = s e l e c t ({s_{P u l s e O n^{T M}}^{j}}, H E A R T_R A T E)$
Comment: measurement takes place for 30 min at default frequency; stop is not mandatory
$p l a y (s, t_{0}, t_{0} + 30 \min)$
Comment: data gathered by HR sensor are stored in XLS format
return $s t o r e (s, P u l s e O n^{T M}, P a t h_{d a t a_{s}}, d a t a_{s}, X L S)$
