In this study, we propose a pen-type interface that uses a vibration motor to reproduces the feeling of writing on paper when writing using a stylus pen on a tablet device. Conventional pen-type interfaces have two problems. First, a delay occurs between the start of writing and the start of vibration. Second, because the frequency and amplitude of the vibration are fixed, the writing feel is not reproducible. Hence, we quantify the degree of time delay that humans can tolerate by conducting sensitivity evaluation experiments. To maintain the time delay within an acceptable range, we utilize an acceleration sensor to acquire the start of a writing action and the writing speed at the interface. This approach can reduce the system delay and ensure a fast response. Based on a subjective evaluation experiment, we confirm that the proposed method does not cause any time delays. To solve the second problem, the vibration generated in the pen when writing on paper at various speeds is measured, and the linear prediction coefficient of the autoregressive model is derived. The vibrations reproduced based on the model are transmitted to a vibrator at the interface in real time to improve the reproducibility of the writing feel. Spectrogram analysis results of the generated vibration confirm that the difference in vibration characteristics based on the writing speed can be reproduced. |
