Abstract
Denne undersøgelse undersøger, om en enhed, der giver real-time vibrotaktil feedback af tonehøjden for en sanger, er levedygtig blandt mange grupper af mennesker. Den bærbare enhed, kaldet SIRTAH (Singing Reinforcement Training Applying Haptics) er designet ved hjælp af en YIN-baseret algoritme til grundlæggende frekvens (f0) eller tonehøjdeestimering i samarbejde med haptisk feedback leveret af en møntvibrationsmotor. To evalueringer udføres på forskellige grupper af begyndersangere (henholdsvis n = 23 og n = 6) i enten et kortsigtet eller langsigtet forsøg med det mål at justere deres sang, indtil de har opnået næsten perfekt tonehøjde. Deres evalueringer indsendes gennem en System Usability Scale, og deres præstation af nøjagtigt sunget noder under forskellige forhold måles. Resultaterne indikerer et acceptabelt niveau af brugervenlighed, men antyder, at der kan foretages justeringer og forbedringer for at opnå levedygtighed.
This study looks into whether a device that provides real-time vibrotactile feedback of the pitch accuracy of a singer is viable amongst many groups of people. The wearable device, named SIRTAH (Singing Reinforcement Training Applying Haptics) is designed using a YIN-based algorithm for fundamental frequency (f0) or pitch estimation in cooperation with haptic feedback provided by a coin vibration motor. Two evaluations are conducted on different groups of novice singers (n = 23 and n = 6, respectively) in either a short-term or long-term trial with the goal of adjusting their singing until they’ve achieved near perfect pitch. Their evaluations are submitted through a System Usability Scale and their performance of accurately sung notes in different conditions are measured. The results indicate a passable level of usability, but suggests that adjustments and improvements could be made to achieve viability.
