| Outline of Annual Research Achievements |
In order to support operation and diagnosis in laparoscopic surgery, I aimed to develop a haptic feedback system based on multiple axial force detection. In the first term of research, I employed the acoustic reflection principle to develop a tactile sensor. The proposed tactile sensor used acoustic waves, which were inserted into two acoustic cavities of the sensor for measuring the applied normal force and shear force. The sensor prototype was fabricated and tested with an artificial gastric phantom. The experimental results showed that the sensor prototype has capable of normal and shear force measurements. Surgeons also are enabled to understand the contact tissue properties such as tumor by evaluating the obtained contact force's components of the developed tactile sensor.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
I have developed the tactile sensor having normal force and shear force measurement function using the acoustic reflection principle for laparoscopic surgery. The sensor performance were accepted in an international conference and I have prepared to submit it in an academic journal. Furthermore, I also start developing necessary devices for the next study. The works are going as well as I expected.

| Strategy for Future Research Activity |
The development of tactile display enables the users easy to intuitively understand the measuring output of the tactile sensor. In next study, I plan to use a pneumatic system to generate the contact force (normal force and shear force) that similar to the measured force received from the tactile sensor. Additionally, in order to evaluate the performance of the tactile feedback system when using the tactile display, some trials will be required to perform psychophysical experiments in a simulating laparoscopic surgery environment, and based on the experiment’s results, I can adjust design parameters of the system. The performance of the system will be analyzed and summarized to submit in an international conference or journal.
