Augmented visualization of the mathematic and scientific data is an essential aid in training blind students’ pre-calculus skills. Compared to existing multidimensional wrench-reflection interfaces, one-dimensional stylus-based interaction concept could support blind users with reasonable feedback in different tasks. We designed a mock-up of the cable-suspended haptic interface and a match game-like piece of software to investigate the perception features of the length of the virtual horizontal bar chart columns augmented with wrench and sound feedback. The performance of the eight blindfolded subjects was evaluated in terms of the number of repeated inspections to detect twin chart columns with similar length, and the task completion time required to perform the chart inspection. The experience acquired within simulated gameplay conditions with the use of implemented cable-suspended interface can be applied in developing novel didactic tools for training blind students in estimating linear dimensions of the simulated objects.
