Abstract-User acceptance of myoelectric forearm prostheses is currently low. Awkward control, lack of feedback, and difficult training are cited as primary reasons. Recently, researchers have focused on exploiting the new possibilities offered by advancements in prosthetic technology. Alternatively, researchers could focus on prosthesis acceptance by developing functional requirements based on activities users are likely to perform. In this article, we describe the process of determining such requirements and then the application of these requirements to evaluating the state of the art in myoelectric forearm prosthesis research. As part of a needs assessment, a workshop was organized involving clinicians (representing end users), academics, and engineers. The resulting needs included an increased number of functions, lower reaction and execution times, and intuitiveness of both control and feedback systems. Reviewing the state of the art of research in the main prosthetic subsystems (electromyographic [EMG] sensing, control, and feedback) showed that modern research prototypes only partly fulfill the requirements. We found that focus should be on validating EMG-sensing results with patients, improving simultaneous control of wrist movements and grasps, deriving optimal parameters for force and position feedback, and taking into account the psychophysical aspects of feedback, such as intensity perception and spatial acuity.

“…These plunger-type actuators feature a very fast rise time (time reach 90 percent of peak force output) of ~ 5 ms (Ref. 13). The device is tuned to a resonance of approximately 250 Hz, coinciding approximately with the frequency at which the Pacinian corpuscle mechanoreceptors in human skin have maximum sensitivity.…”

“…In this experiment, two EAI C2 Tactors [16] from Engineering Acoustics were chosen to present the different sets of vibrotactile feedback ( Figure 1). The audio feedback was presented through headphones attached to a Nokia N810 Internet touchscreen tablet (europe.nokia.com/nseries/).…”

We report the results of a study focusing on the meanings that can be conveyed by audio and tactile icons. Our research considers the following question: how can audio and tactile icons be designed to optimise congruence between crossmodal feedback and the type of information this feedback is intended to convey? For example, if we have a set of system warnings, confirmations, progress updates and errors: what audio and tactile representations best match the information or type of message? Is one modality more appropriate at presenting certain types of information than the other modality? The results of this study indicate that certain parameters of the audio and tactile modalities such as rhythm, texture and tempo play an important role in the creation of congruent sets of feedback when given a specific type of information to transmit. We argue that a combination of audio or tactile parameters derived from our results allows the same type of information to be derived through touch and sound with an intuitive match to the content of the message.
