01. Action is beyond space
Until today, we are able to touch only objects that exist in the space right in front of us and perform/behave things against objects that exist at the same time. By using this technology, however, these spatial and temporal restrictions can be removed. Even a person who is away from a work object, he/she can adjust the level of pressure and execute tasks flexibly according to the situation. For example, a doctor in the hospital can remotely examine a patient at home and perform palpation. Thus, an operator in a central control room can carry out many tasks together, safely and efficiently by connecting to remote locations: hazardous environments, including high-altitude or deep-sea areas, and workplaces that require physical labor such as picking up baggage in a large warehouse.
02. Digitalization of human action
The acquisition of force information from human motion was difficult with conventional methods such as motion capture, although position information could be measured. The visual information can tell whether we are opening or closing our hand, but it cannot measure how hard we are gripping. On the other hand, the real haptics digitizes human motion in both position and force information. Therefore, this can decipher expert techniques of the master craftsmanship and convert tacit knowledge into explicit knowledge. So, this technology enables to pass the expert techniques onto non-experts with the aid of the explicit knowledge. As an application, a training simulator containing expert's information helps to train efficient/effective actions and approaches to anomalies/accidents.
03. Becoming superhuman
Once the human motion is digitized, the data can be edited as desired. For example, if the power of a worker can be magnified and transmitted to the real avatar, it is possible to perform heavy work for human workers more powerfully and immediately. This editing technique is indispensable for gigantic robot operations coming out in animated films and for large-scale work using construction machines. On the contrary, if the power can be diminished and transmitted, the real avatar would process subtle and delicate tasks more precisely. This technique can also amplify the small force, which a human operator cannot detect, and feedback to the operator. Moreover, it can fast-forward and reverse the recorded human motion similarly to audio and visual technologies. By speeding up and reproducing the recorded data, the real avatar can boost the productivity at an incredible speed that is superior to the human capacities and exceed human competences.
04. Digital content of action
With developing the human motion database by sharing information of acquired various motions on the cloud and, we can download the saved motion data and reproduce it as needed. In other words, without storing human motion every time, we are able to realize the desired action whenever and wherever we want. Our team calls this concept "Internet of Actions (IoA)" and advocates it as the next movement following IoT. In the world of IoT, we could know if an elderly person falls down by checking the load of the bed or the illumination condition of the toilet, as in the IoA world, we can even help the elderly get up or provide emergency medical measures such as an automated external defibrillator.
05. Digitalization of reaction from contact objects
Real haptics can digitize not only the human action but also the reaction from the contact object. For example, the digitization of agricultural crops enable us to calculate their hardness and quantitatively evaluate the crop maturity, and even hardness or moistness of the soil too by inserting a stick into soil . Moreover, this enables to measure the viscosity of liquids and the stiffness of organs quantitatively .
