F: Examples of Products

 Introduction



Becker (1999) describes a few products that have been developed with accessibility in mind. They include Emacspeak (a screen reader), Java Accessibility API (which gives developers more power to include accessible features in the software rather than needing to supply add-ons), and OCR (this translates print to computer text which can be manipulated). Unfortunately, very few products have been designed from the ground up with accessibility in mind. It is much more likely that we will find examples of products with accessible features added.

Much more work has been done in the realm of assistive technologies, but companies are working toward more accessible design. There have been numerous efforts to increase accessibility to the web (Engelen, et al, 1999), and this is one of the best attempts to make a product truly accessible without calling out any particular disability. Macromedia, Microsoft, NCR, Pacific Bell, Qualcomm, Red Hat, and Sun Microsystems, among others, have developed accessibility policies and have included individuals with disabilities in product design and evaluation. Vanderheiden (n.d.) identifies a number of attempts to improve access for the various impairment groups.



 F-1. What are the existing attempts to develop products in the spirit of Accessible Design?



There are several attempts in industry to develop commercial products in the spirit of accessible design, especially in big companies (e.g., Internet World, 2000; Macromedia, 2000, NCR, 2001; Pacific Bell, 1996; Qualcomm, 1999; Sun Microsystems, 2000). Such products include cell phones that are more compatible with assistive listening devices (TIA Access, 1999a; 1999b, 1999c), PDF files that are more compatible with assistive reading devices (Adobe, 1999), and kiosk terminals with touchscreen input and private voice-assisted leadthrough (NCR, 2001). In a letter to President Clinton (September, 2000), technology executives from several companies vowed to lead industry efforts in incorporating accessible design principles into the design process. Award programs sponsored by disability advocacy groups, such as the American Foundation for the Blind (AFB) and Self Help for Hard of Hearing People (SHHH), further support industry efforts by providing publicity for accessible products (AFB, 2000; RNIB, 2000; TIA Access, 1999a, 1999b).

 F-2. What are the perceived strengths and weaknesses of accessible products?



The perceived strengths of accessible products are that they increase the productivity and independence of people with disabilities and are easier to use by people who do not have disabilities (Access Board, n.d.; Taylor, 2000; TIA Access, 1996). In addition, accessible products are perceived as being more flexible for use in situations where individuals without disabilities may experience temporary impairment (e.g., environments with a great deal of noise, Vanderheiden, 1997).

There are three perceived weaknesses of accessible products that are commonly cited as reasons for not incorporating accessible design principles in the design process. The first is that accessible products cannot be truly accessible to everyone. Developers in industry fear that misperceptions about the promise of accessible design could lead to increased customer dissatisfaction and thus increased litigation (Trace Center, n.d.). The second perceived weakness is that accessible products, in order to be more accessible to people with disabilities, must necessarily be less aesthetically appealing. Individuals with disabilities, however, appreciate cosmetic appeal just as much as individuals without disabilities (King, 1999). The third perceived weakness is that accessible products are more expensive and time consuming to produce (Trace Center, n.d.).
