“…This concern has been revealed in the related scholarship. Annett, Anderson, Bischof, and Gupta (2014), and Helps and Helps (2016) categorized stylus pen as "active and passive" based on the use in capacitive touchscreens. The prices of active stylus pens are higher than the passive ones (Annett et al, 2014;Tanyag & Atienza, 2015).…”

“…Therefore, the widespread use of stylus pen seems to be limited and constrained in near future due to economic costs. In addition, not all active stylus pen are compatible with all brands/tablet models (Helps & Helps, 2016;Tanyag & Atienza, 2015).…”

, 171 pages Handwriting is one of the most important and essential skills for both literacy and beyond. However, some students may have difficulty in writing. Dysgraphia, expressed as the disorder of written expression, is the state of writing skills being below the expected level of intelligence, age, and education of the student. The main purpose of the study is to examine the effectiveness of the mobile writing application for students with dysgraphia and to determine whether there is an improvement in writing skills of the students after using this application. A mixed method design was employed in this study. 11 students with dysgraphia were participated to the study. To sum up, the results of this study revealed: 1) Experts' views before the quasiexperimental design were very positive. The aspects need to be improved were modified before the experiment. 2) The mobile writing application contributed to acquire writing skills (letter, spells, and words) for students with dysgraphia. 3) Students' percentages of on-task durations were in a range of 80% and 100%. When the writing speed of students session by session were examined, there was an increase in all of them. The correct attempts of the students were increased session by session vi and the number of incorrect attempts decreased. The line violation of the students tended to decrease session by session. The frequency of the third-degree clue tends to decrease the session by session while the other clue types seem to be at the same level or tend to increase 4) Special education teachers' views were positive about mobile writing application.

“…Wang et al [2016] proposed to use electrovibration to replicate the frictional properties of a stylus. The main limitation of active modulation is the significant latency introduced by the mechanical components [Annett et al 2014;Helps and Helps 2016]. Our passive tools avoid this problem and benefit from providing an immediate haptic response to the users.…”

Fabrication-in-the-loop co-optimization of surfaces and styli for drawing haptics

Digital drawing tools are now standard in art and design workflows. These tools offer comfort, portability, and precision as well as native integration with digital-art workflows, software, and tools. At the same time, artists continue to work with long-standing, traditional drawing tools. One feature of traditional tools, well-appreciated by many artists and lacking in digital tools, is the specific and diverse range of haptic responses provided by them. Haptic feedback in traditional drawing tools provides unique, per-tool responses that help determine the precision and character of individual strokes. In this work, we address the problem of fabricating digital drawing tools that closely match the haptic feedback of their traditional counterparts. This requires the formulation and solution of a complex, co-optimization of both digital styli and the drawing surfaces they move upon. Here, a potentially direct formulation of this optimization with numerical simulation-in-the-loop is not yet viable. As in many complex design tasks, state-of-the-art methods do not currently offer predictive modeling at rates and scales that can account for the numerous, coupled, physical behaviors governing the haptics of styli and surfaces, nor for the limitations and uncertainties inherent in their fabrication processes. To address these challenges, we propose fabrication-in-the-loop optimization. Critical to making this strategy practical we construct our objective via a Gaussian Process that does not require computing derivatives with respect to design parameters. Our Gaussian Process surrogate model then provides both function estimates and confidence intervals that guide the efficient sampling of our design space. In turn, this sampling critically reduces the numbers of fabricated examples during exploration and automatically handles exploration-exploitation trade-offs. We apply our method to fabricate drawing tools that provide a wide range of haptic feedback, and demonstrate that they are often hard for users to distinguish from their traditional drawing-tool analogs.
