“…The main drawbacks of laparoscopic surgery are reduced tactile and depth perception, which could be critical in many surgical procedures ( e.g. , segmental colectomy for small malignant polyps)[ 21 ]. Where feasible, we suggest endoscopic procedures for such lesions and, if surgery is required, preoperative endoscopic tattooing could help intraoperative identification of the pathology[ 22 , 23 ].…”

Laparoscopic surgery has many advantages over open surgery. At the same time, it is not without its risks. In this review, we discuss steps that could enhance the safety of laparoscopic surgery. Some of the important safety considerations are ruling out pregnancy in women of the childbearing age group; advanced discussion with the patient regarding unexpected intraoperative situations, and ensuring appropriate equipment is available. Important perioperative safety considerations include thromboprophylaxis; antibiotic prophylaxis; patient allergies; proper positioning of the patient, stack, and monitor(s); patient appropriate pneumoperitoneum; ergonomic port placement; use of lowest possible intra-abdominal pressure; use of additional five-millimetre (mm) ports as needed; safe use of energy devices and laparoscopic staplers; low threshold for a second opinion; backing out if unsafe to proceed; avoiding hand-over in the middle of the procedure; ensuring all planned procedures have been performed; inclusion of laparoscopic retrieval bags and specimens in the operating count; avoiding 10-15 mm ports for placement of drains; appropriate port closures; and use of long-acting local anaesthetic agents for analgesia. Important postoperative considerations include adequate analgesia; early ambulation; careful attention to early warning scores; and appropriate discharge advice.

“…While the proposed tracking system is free of those issues mentioned above, limitations still exist. In particular, the attribute of contact force and pressure are unavailable although they contribute to contact interactions ( Essick et al, 2010 ; Huang et al, 2020 ; Teyssier et al, 2020 ; Xu et al, 2020 ). Due to the constraint of recording frequency, fast movements might fail in tracking since the hand image could be blurred.…”

3D Visual Tracking to Quantify Physical Contact Interactions in Human-to-Human Touch

Across a plethora of social situations, we touch others in natural and intuitive ways to share thoughts and emotions, such as tapping to get one’s attention or caressing to soothe one’s anxiety. A deeper understanding of these human-to-human interactions will require, in part, the precise measurement of skin-to-skin physical contact. Among prior efforts, each measurement approach exhibits certain constraints, e.g., motion trackers do not capture the precise shape of skin surfaces, while pressure sensors impede skin-to-skin contact. In contrast, this work develops an interference-free 3D visual tracking system using a depth camera to measure the contact attributes between the bare hand of a toucher and the forearm of a receiver. The toucher’s hand is tracked as a posed and positioned mesh by fitting a hand model to detected 3D hand joints, whereas a receiver’s forearm is extracted as a 3D surface updated upon repeated skin contact. Based on a contact model involving point clouds, the spatiotemporal changes of hand-to-forearm contact are decomposed as six, high-resolution, time-series contact attributes, i.e., contact area, indentation depth, absolute velocity, and three orthogonal velocity components, together with contact duration. To examine the system’s capabilities and limitations, two types of experiments were performed. First, to evaluate its ability to discern human touches, one person delivered cued social messages, e.g., happiness, anger, sympathy, to another person using their preferred gestures. The results indicated that messages and gestures, as well as the identities of the touchers, were readily discerned from their contact attributes. Second, the system’s spatiotemporal accuracy was validated against measurements from independent devices, including an electromagnetic motion tracker, sensorized pressure mat, and laser displacement sensor. While validated here in the context of social communication, this system is extendable to human touch interactions such as maternal care of infants and massage therapy.

“…The humanoid robot hand has been developed with different types of sensors for various applications such as medical [ 5 , 45 , 46 ], industrial [ 8 , 30 ], and home use applications [ 5 ]. One of the significant developments in data processing is the tactile sensor for the object recognition capability of robots [ 36 , 39 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 ].…”

A tactile sensor array is a crucial component for applying physical sensors to a humanoid robot. This work focused on developing a palm-size tactile sensor array (56.0 mm × 56.0 mm) to apply object recognition for the humanoid robot hand. This sensor was based on a PCB technology operating with the piezoresistive principle. A conductive polymer composites sheet was used as a sensing element and the matrix array of this sensor was 16 × 16 pixels. The sensitivity of this sensor was evaluated and the sensor was installed on the robot hand. The tactile images, with resolution enhancement using bicubic interpolation obtained from 20 classes, were used to train and test 19 different DCNNs. InceptionResNetV2 provided superior performance with 91.82% accuracy. However, using the multimodal learning method that included InceptionResNetV2 and XceptionNet, the highest recognition rate of 92.73% was achieved. Moreover, this recognition rate improved when the object exploration was applied to demonstrate.
