 The Design Fidelity Score measures how completely and correctly each wizard implemented the written specification. Scores range from 0 to 100, with full points awarded only when a component is both present and correct.
 
-W-01 (Choregraphe) received a DFS of 42.5. Analysis of the exported project file found all four interaction steps present and correctly sequenced; the conditional branch was wired and functional. Speech fidelity was partial: W-01 deviated from the specification by substituting a different rock color in the narrative and comprehension question, departing from the ``red'' specified in the paper protocol. Items 1 and 4 (introduction and branch responses) received full points; items 2 and 3 received half points due to the content mismatch. The gesture category scored zero. Both the introduction wave and the narrative gesture were implemented via the tool's \emph{Animated Say} function, which generates motion non-deterministically from a library rather than placing a specific gesture node; under the rubric's clarifying rule, this does not satisfy the Correct criterion. Item 7 (nod or head shake) was not explicitly programmed. The control-flow category was split: item 9 (correct step sequence) received full points; item 8 (conditional branch) received half points because the branch was resolved by manually deleting and re-routing connections during the trial rather than through a dedicated conditional node wired at design time.

W-03 approached the design as a block programming exercise, constructing extra nodes and attempting a concurrent execution structure not called for by the specification. One C-type clarification was required: I noted that control-flow logic relying on onboard speech recognition was outside the scope of this study, since Wizard-of-Oz execution routes all speech decisions through the wizard rather than the robot. Speech fidelity was partial: two of the three scorable speech items were present, with not all delivered correctly. No conditional branch was implemented in the final design, resulting in zero points for that category. The design phase extended to 37 minutes, seven minutes over the 30-minute allocation.

The design phase ran 35 minutes without reaching completion, making W-04 the only wizard in the study who did not finish the design before the cutoff. Four T-type tool-operation interventions and one C-type clarification were logged. During training, W-04 asked about running two behavior blocks simultaneously and how to edit a block, reflecting early engagement with Choregraphe's concurrent flow model. During the design phase, W-04 asked about interpretation of punctuation in speech content, generating three simultaneous T-type marks across items 1--3. W-04 also independently attempted to use Choregraphe's choice block for conditional branching; the block did not execute correctly. The researcher re-explained the WoZ execution model and how to branch by manual step selection. Speech items 1, 2, and 4 received full points; item 3 (the comprehension question) was absent from the final design. Gesture items 5 and 6 received full points; item 7 (nod or head shake) was present but not marked correct (5/10). The conditional branch received zero points; no functional branch was wired at export. Step sequencing received partial credit (7.5/15).

 W-05 (HRIStudio, Chemical Engineering, no programming experience) received a DFS of 100. The design phase completed in 18 minutes, the shortest design phase in the study. Training concluded in 6 minutes with no questions asked; the wizard described the platform as ``pretty straightforward.'' Two T-type interventions and three C-type clarifications were logged during the design phase. The T-type interventions concerned editing properties in the right pane of the experiment designer and understanding that the branch block requires predefined steps; both were addressed without affecting the final design. The C-type clarifications concerned what ``steps'' represent as structural containers, the relationship between the written specification's speech and platform speech actions, and a related conceptual question. The wizard added a creative narrative gesture not specified in the protocol (a crouch animation); this was present and correct under the rubric. The DFS assessment noted that the wizard's design mapped well from the specification.

+W-06 (HRIStudio, Computer Science, extensive programming) received a DFS of 100. Two T-type interventions were logged during the design phase, both pertaining to item 6 (narrative gesture): at 15:21, W-06 attempted to use parallel execution for a gesture action and was unable to edit the action node; at 15:24, W-06 encountered difficulty resetting the robot's posture and was directed to recommended posture blocks. In both cases, W-06 resolved the issue independently after the initial prompt. W-06's programming background led to a more elaborate design than the specification required, including extra posture-reset actions that were ultimately redundant since the robot was already in the correct starting position; these additions did not affect scoring since all required actions were present and correct in the exported project file. The conditional branch was wired correctly, and all speech and gesture items matched the specification. W-06 completed the design in 21 minutes, within the 30-minute allocation.

 \subsection{Execution Reliability Score}
 
-The Execution Reliability Score measures how faithfully the designed interaction executed during the live trial. W-01 received an ERS of 65. The trial ran for approximately five minutes. In this session, I served as the test subject during the live trial. Through that experience I confirmed that a separately recruited participant is not required: the DFS and ERS both evaluate the wizard's implementation and execution fidelity rather than a subject's behavioral responses. Subsequent sessions therefore run the trial phase with the wizard executing the designed interaction directly, without a separate test subject. The introduction speech and gesture executed correctly. The narrative speech executed but deviated from the specification due to the modified rock color described above. The comprehension question was delivered, a branch response was triggered, and the interaction proceeded to its conclusion. Gesture synchronization was partial: a pause gesture executed, but coordination between speech and movement was inconsistent at several points. No system disconnections or crashes occurred.

 W-02 (HRIStudio) received an ERS of 95. The trial ran for approximately five minutes. Introduction speech and gesture, narrative speech, comprehension question, and branch response content all executed correctly and matched the specification. During the trial, the interaction briefly advanced to an incorrect step when a branch transition misfired; this was immediately corrected by manually selecting the correct step in the execution interface. This incident was logged as an H-type intervention (platform behavior, not wizard error). The branching item scored 5 out of 10 on its own merits: the branch was present in the design and execution reached the branch step, but the initial misfire meant the transition was not fully correct before manual correction. No other deviations or system failures occurred.

 W-05 (HRIStudio) received an ERS of 95. The trial ran for approximately four minutes and reached step 4. The researcher's answer was ``Red'' (the correct answer), and branch A fired via programmed conditional logic. All speech items executed correctly. Introduction gesture, nod or head shake, speech synchronization, and the pre-question pause all scored full points. One trial intervention pair was logged: the researcher briefly forgot they were in live execution (G-type), then was reminded and manually skipped a non-functional crouch action (T-type, capping item 6 at 5/10). The crouch animation exists in HRIStudio's action library but does not execute on the NAO6 robot-side; skipping it was the correct recovery. All other items scored full points and no system errors occurred. The overall ERS assessment recorded that the interaction executed as designed.

In the HRIStudio condition, branching was present in every design and executed correctly in every trial; no trial required tool-operation guidance from the researcher to complete. In the Choregraphe condition, branching was absent from two of three designs (W-03, W-04) and was resolved by manual redesign during the trial in the third (W-01).
 
 \subsection{System Usability Scale}
 
 W-01 rated Choregraphe with a SUS score of 60. The standard benchmark for SUS scores places 68 as the average; scores below 68 are generally considered below average usability~\cite{Brooke1996}. A score of 60 suggests that W-01, a Digital Humanities faculty member with no programming background, found Choregraphe marginal in usability; this outcome is consistent with the high volume of interface-level help requests observed during the design phase.
 
-W-02 rated HRIStudio with a SUS score of 90, well above the average benchmark of 68 and the highest score observed so far.

Importantly, none of the clarifications blocked design completion, and the final DFS was unaffected. The C-type pattern for W-05 reflects a different kind of engagement from Choregraphe's T-type pattern: questions about what the tool means rather than how to operate it.

 A notable qualitative finding from W-01's session was an unprompted deviation from the written specification: the wizard substituted a different rock color in the robot's speech and comprehension question, departing from the ``red'' specified in the paper protocol. This was not a tool failure; the wizard made a deliberate creative choice that the tool did not prevent or flag. The deviation was undetected until the live trial, when it surfaced during execution. This incident illustrates the reproducibility problem concretely: without automated protocol enforcement, wizard behavior can drift from the specification in ways that are invisible until execution, affecting the validity of the resulting interaction data.
 
-No specification deviations from the written protocol were observed in W-02, W-04, or W-05. W-03 introduced extra nodes beyond the specification's scope, which was addressed by a C-type clarification during design. W-05 added a creative gesture not required by the specification (crouch), which was not a deviation from the protocol's content but an elaboration of the gesture category; it scored within the rubric and was noted for completeness. The speech substitution incident in W-01 remains the only case of content drift from the written specification, and it occurred exclusively in the Choregraphe condition.

 W-01 expressed that the training was comprehensible and that the underlying logic of the task was clear. The primary source of frustration was Choregraphe's interface for handling conditional branches and managing the timing of parallel behaviors. Post-session comments suggested that the wizard would not use Choregraphe independently for future HRI work without technical support.

+W-06 approached the design with a programmer's instinct for thoroughness, initially exploring parallel execution structures for gesture actions and adding posture-reset steps beyond what the specification called for. The two T-type design-phase interventions reflected this exploratory behavior rather than confusion about the task. The extra posture-reset actions in the final design were redundant in practice since the robot was already in the correct starting position, but they did not interfere with the required items and the design achieved a perfect DFS. W-06's trial ran entirely without researcher intervention, producing the only perfect ERS in the study. The session illustrates a different accessibility profile from W-05: where W-05 encountered no interface friction at all, W-06's programming background produced brief exploratory detours that the platform absorbed without compromising the final design or execution.

The direction of the evidence across all measures consistently favors HRIStudio. Chapter~\ref{ch:discussion} interprets these findings in the context of the research questions.
