“…The goal of this approach is to design devices that more closely fit the needs of the intended user population (Nielsen & Landauer, 1993). While user testing can be a challenge in device development for smaller target audiences, such as individuals with visual impairments, many of the studies included in this review successfully incorporate extensive user testing into the device design process (Ashcroft, 1983;Tzovaras, Nikolakis, Fergais, Malasiotis, & Stavrakis, 2004;Ando, Tsukahara, Seki, & Fujie, 2012).…”

To lay the groundwork for devising, improving, and implementing new technologies to meet the needs of individuals with visual impairments, a systematic literature review was conducted to: a) describe hardware platforms used in assistive devices, b) identify their various applications, and c) summarize practices in user testing conducted with these devices. A search in relevant EBSCO databases for articles published between 1980 and 2014 with terminology related to visual impairment, technology, and tactile sensory adaptation yielded 62 articles that met the inclusion criteria for final review. It was found that while earlier hardware development focused on pin matrices, the emphasis then shifted toward force feedback haptics and accessible touch screens. The inclusion of interactive and multimodal features has become increasingly prevalent. The quantity and consistency of research on navigation, education, and computer accessibility suggest that these are pertinent areas of need for the visually impaired community. Methodologies for usability testing ranged from case studies to larger cross-sectional studies. Many studies used blindfolded sighted users to draw conclusions about design principles and usability. Altogether, the findings presented in this review provide insight on effective design strategies and user testing methodologies for future research on assistive technology for individuals with visual impairments.

This paper presents a minimalistic handheld haptic interface designed to provide pedestrian navigation assistance via the intuitive and unobtrusive stimulus of shapechanging. The new device, named the Haptic Taco, explores a novel region of robotic interfaces which we believe to have benefits over other communication methods. In previous work, we demonstrated the use of a 2DOF shape changing interface for navigation without the use of sight. In this paper we seek to explore the potential of minimal 1DOF interfaces, whose simplicity may increase intuitiveness and performance despite conveying less information. The Haptic Taco utilizes the same 'variable volume' concept as a previous device, the Haptic Lotus (2010), but with reduced body compliance and higher force exertion capability. Both devices modulate their perceived volume in relation to proximity to a navigational target (a destination or waypoint). As users walk within an environment, they also attempt to minimize the device volume, finding targets via an embodied 'steepest descent' method. Experimental comparison of the Lotus and Taco in a targetfinding study revealed that the Taco interface increased motion path efficiency by 24% over the Lotus, to 47% average efficiency. This result is highly comparable to the mean motion efficiency of 43.6-48% observed in prior experiments with the 2DOF shape-changing interface, the Animotus. The findings indicate the potential for minimalistic interfaces in this emerging field.

“…Skin stretch tactors have conveyed direction on the finger pad [17]. Spinning flywheels [18], miniature mass-spring-dampers [19] and moving weights [20] have all been used to generate ungrounded directional force effects. An unusual device, Pull-Navi, pulled the ears of a user in various directions to provide navigation guidance [21].…”
