An accessible, nontechnical overview of active touch sensing, from sensory receptors in the skin to tactile surfaces on flat screen displays. Haptics, or haptic sensing, refers to the ability to identify and perceive objects through touch. This is active touch, involving exploration of an object with the hand rather than the passive sensing of a vibration or force on the skin. The development of new technologies, including prosthetic hands and tactile surfaces for flat screen displays, depends on our knowledge of haptics. In this volume in the MIT Press Essential Knowledge series, Lynette Jones offers an accessible overview of haptics, or active touch sensing, and its applications. Jones explains that haptics involves integrating information from touch and kinesthesia-that is, information both from sensors in the skin and from sensors in muscles, tendons, and joints. The challenge for technology is to reproduce in a virtual world some of the sensations associated with physical interactions with the environment. Jones maps the building blocks of the tactile system, the receptors in the skin and the skin itself, and how information is processed at this interface with the external world. She describes haptic perception, the processing of haptic information in the brain; haptic illusions, or distorted perceptions of objects and the body itself; tactile and haptic displays, from braille to robotic systems; tactile compensation for other sensory impairments; surface haptics, which creates virtual haptic effects on physical surfaces such as touch screens; and the development of robotic and prosthetic hands that mimic the properties of human hands.

When Angela Davis (b. 1944) was placed on the FBI's Ten Most Wanted list in 1970 and after she successfully gained acquittal in the 1972 trial that garnered national and international attention, she became one of the most recognizable and iconic figures in the twentieth century. An outspoken advocate for the oppressed and exploited, she has written extensively about the intersections between race, class, and gender; Black liberation; and the US prison system. Conversations with Angela Davis seeks to explore Davis's role as an educator, scholar, and activist who continues to engage in important and significant social justice work. Featuring seventeen interviews ranging from the 1970s to the present day, the volume chronicles Davis's life and her involvement with and influence on important and significant historical and cultural events. Davis comments on a range of topics relevant to social, economic, and political issues from national and international contexts, and taken together, the interviews explore how her views have evolved over the past several decades. The volume provides insight on Davis's relationships with such organizations as the Student Nonviolent Coordinating Committee, the Communist Party, the Green Party, and Critical Resistance, and how Davis has fought for racial, gender, and social and economic equality in the US and abroad. Conversations with Angela Davis also addresses her ongoing work in the prison abolition movement.
