“…For these four participants we analysed the variation in striking velocity across latency conditions to test if their reports of increased force of strike was influenced by ACTION-SOUND LATENCY, PERCEIVED INSTRUMENT QUALITY latency condition. We found that for these participants there was indeed an increased mean velocity of strike for 20ms and 10±3ms latency in comparison to the zero latency condition (Jack, Stockman, & McPherson, 2016).…”

Asynchrony between tactile and auditory feedback (action-sound latency) when playing a musical instrument is widely recognized as disruptive to musical performance. In this paper we present a study that assesses the effects of delayed auditory feedback on the timing accuracy and judgments of instrument quality for two groups of participants: professional percussionists and non-percussionist amateur musicians. The amounts of delay tested in this study are relatively small in comparison to similar studies of auditory delays in a musical context (0 ms, 10 ms, 10 ms ± 3 ms, 20 ms). We found that both groups rated the zero latency condition as higher quality for a series of quality measures in comparison to 10 ms ± 3 ms and 20 ms latency, but did not show a significant difference in rating between 10 ms latency and zero latency. Professional percussionists were more aware of the latency conditions and showed less variation of timing under the latency conditions, although this ability decreased as the temporal demands of the task increased. We compare our findings from each group and discuss them in relation to latency in interactive digital systems more generally and experimentally similar work on sensorimotor control and rhythmic performance.

“…We believe that there is a certain subjective dimension to interpolation which should not be ignored. We draw an analogy to the effects of latency on musical input -if latency is consistent, it is perceived as a property of the feel of the instrument, but if the latency varies, it is perceived as negatively impacting the quality of the instrument [12]. In our case it is not clear how relevant the average accuracy or even precision is, compared to the consistency and 'feel' of the errors.…”

This paper provides resources and design recommendations for optimizing position input for pressure sensor matrices, a sensor design often used in eTextiles. Currently applications using pressure matrices for precise continuous position control are rare. One reason designers opt against using these sensors for continuous position control is that when the finger transitions from one sensing electrode to the next, jerky motion, jumps or other non-linear artifacts appear. We demonstrate that interdigitation can improve transition behavior and discuss interpolation algorithms to best leverage such designs. We provide software for reproducing our sensors and experiment, as well as a dataset consisting of 1122 swipe gestures performed on 17 sensors.

“…Also, to grant versatility in the design of vibrotactile cues, actuators' frequency response and dynamic range should be as wide as possible, and their onset/stop time negligible. For example, while it is known that piano mechanics results in variable delay between action and audio-tactile feedback [1], to have full control over this aspect while designing keyboard-based DMIs, audio and tactile devices should offer the lowest possible latency [7,17].…”

Routing continuous analog signals is also a delicate issue, since the end user must not notice any disturbance or delay in the feedback.…”

While a standard approach is more or less established for rendering basic vibratory cues in consumer electronics, the implementation of advanced vibrotactile feedback still requires designers and engineers to solve a number of technical issues. Several off-the-shelf vibration actuators are currently available, having different characteristics and limitations that should be considered in the design process. We suggest an iterative approach to design in which vibrotactile interfaces are validated by testing their accuracy in rendering vibratory cues and in measuring input gestures. Several examples of prototype interfaces yielding audio-haptic feedback are described, ranging from open-ended devices to musical interfaces, addressing their design and the characterization of their vibratory output.
